mapping your 6 room dungeon

i will be doing a second set of tables for each type

Giger, the artbook for game Scorn and some of my past work on alien biozones in generation ships and my Xor setting. My Stone Age sorcery book had some stuff for this too.

Eldritch Monolith

In certain desolate places in the world, you can find prehuman ruins of the age of darkness. Each of the four directions you can find them, and there are some cities with eldritch catacombs beneath them. The largest are in remote or dangerous places thought of as lifeless. A great coastal city on the coast of the frozen north, a desert city sometimes revealed in the sand or deep in the caverns of the underland. The oldest ruins are for prehumans and possibly non-humanoid and the most alien. In the Middle period the various beast abhumans in service to the monster kings. The later ones even had humans and orc slaves and the demon gods and planar overlord idols will actually be familiar to modern peoples. Most people shun these places and priests will warn people of meddling with them. Humanity is better off forgetting these places. The interior climate may be very different to outside. They are often cool and absorb heat energy. May have mist inside or even interior weather in large chambers. Very little is flammable inside.

Doorways often have rounded arches, and some have membrane curtain seals.
Some have fleshy sphincter gates or toothy mouthlike portculis.
See through crystal pane or forcewall walls are possible.
Do add local environment decor. Is it in the sea or desert or snow?
Who came here and died in the last few thousand years?

12 Elder crinoid alien wizard, barrel-shaped with tentacles, starfish head and shrunken folding wing membranes

d12 Eldritch Monolith Entry

1 Black obsidian tower with a strange ward on stone door slab. Inside is long abandoned but their is a stone lid covering stairs into the deep. A creature might use as a lair or shelter. Humanoids might use as a base. Haunting or guardian being likely also 

2 Icy cold black dripping cave in process of thawing. Frozen melting creatures here may attract carnivores or bears or even tribal hunters. Pools of pure water may have some trilobites or other marine invertebrates. Slippery, wet holes and pits go deeper

3 Dripping sinkhole into an ancient complex in the deep. What seemed to be a cave with cave art and bones of fallen prehistoric beasts has under calcium formations, has stone doors. Other pillars and features are strangely uniform and made by intelligence. A calcium-encrusted panel of crystals can be cleaned and used to open doors and adjust the environment and light. Tribal folk think this place is taboo. There may be a fallen madman, ghouls or undead megafauna in here or an evil guardian spirit. Passages go down to deeper chambers

4 Mysterious crack in the earth with a strange-smelling mist. Inside is a green crystal chamber with sealed crystal doors. They can be shattered or opened with spells. Crystaline guardians or statues may guard here

5 Mysterious crystal doorway in the cliff visible under certain stars. Can be detected with nagic or is you can see invisible. Magic might be required to open it. Inside is a humming, glowing chamber  

6 Beneath a stone slab with a warning script under a ruined old temple. Inside is a black stone chamber with sealed basalt doors. Some kind of magic trap is likely here, and a guardian protects and repairs the complex

7 Through a doorway high up on a cliff, mostly hidden by shadows. Difficult to spot and requires a climb to reach it. In the opening chamber with fossils in walls are remains of a ancient burial and older passages beyond. Undead or a spirit might dwell here

8 Passages in the bottom of stone sarcophagi in a ruined tomb. The passage is older and seems to be biological material like roots or bones or flesh. Creatures live in the walls and will swarm or ambush with hit-and-run tactics. Possibly worms, bugs or giant vermin dwell here, and passages go into the deep. Opening fleshy doors requires the manipulation of nerve ganglia nodes    

9 Circular, perfect hole cut into rock, possibly blocked with stones later. Chamber within with sloping passages and pit exits. The room is round or square and perfectly formed, possibly with magic or superior stonework. Weird loners, witches and cults like this haunted place for its strange aura. Animals shun it

10 Trapped temple ruin with warning symbols of the ancients. Wall art depicting the history of dealings with alien horrors of the outer void frames far older passages below. A guardian might be left to keep mortals out

11 Excavation site with mounds of dirt, dools and the exposed passage into the dungeon. Someone has come to this place with a work crew camp and worked this site. They found a stone-sealed door with warnings. Opening it killed the leaders and drove off the workers. The final pit has opened at least one stone door with various tents around it, with finds and rubble being sorted. Mounds of sorted broken stone urns, bones and fragments with symbols lay around the pit. A guardian will be hiding somewhere, watching 

12 Opened a portal, possibly activated from a scroll or by a relic leads to a portal entry room. Other possibly broken portals or teleporter pads are around the chamber. Broken masonry and dead intruders remains are scattered about. A guardian being protects the portals and some try to maintain the complex 

d12 Eldritch Monolith Sub Rooms

1 Slimy chaos frog demon bound here, released if opened

2 Shelves of alien tablets of occult lore of evil

3 Reliquary with an alien tool, weapon or magic item on a shelf

4 Stone sarcophagi with magic symbols, might be inhabited by sleeping being

5 Mumified corpse, possibly will reanimate or crumble to dust if opened

6 Slime or ooze creature currently dormant

7 Cacoon of some giant bug or worm

8 Pulsating, glowing organic globes with rapidly growing guardian creatures

9 Shadows or a wraith with funeral urns inside

10 Gas or foul odour and some creature corpse that melts into slime when open, may have toxic or diseased miasma

11 Creature in a stasis field with a gem-studded altar

12 Portal with a gem-studded altar, might be open to another plane, possibly elemental or a distant ruin or elsewhere in a complex

d12 Eldritch Monolith Main Room

1 Reliquary of artefacts. Polygon-shaped niches with crystal panes cover strange alien artefacts. Most are magical or biological specimens in a state of stasis. A control panel can open the screens and play sound recordings of strange speech or illusions of alien beings interacting or studying the relics. Guardians and traps are likely. The items do not operate like familiar magic items; most cost the user some resource or temporary attributes or levels. Some cause psychic trauma.

2 Stasis chambers with a polygon symbol on the floor, some are plain, others have a shaft of light from above trapping them in stasis like a crystal column. Each has a crystal control console which can release stasis-trapped beings or turn them to dust or trap intruders. Beings trapped here can be castly old or even recent bumbling thieves or cultists  

3 Portal chamber with a large portal with huge doors and stairs. Likely closed and locked with magic. Linked to an elemental world, some era in the past or a slimy demonic plane. Opening the door is likely to welcome invaders, and a guardian and a trap is possible to prevent that

4 Alien laboratory with a great central slab with benches around it with bottles and unfamiliar tools. Alien machines on armatures can be lowered from above to assist. Several crystal screens show images of past experiments if controls are touched. Cylindrical columns with bubbling fluids have strange creatures growing in them or possibly just brains and nervous systems or other horrors. Some former experiment or automaton might still remain

5 Alien library with vast collections of tablets, conical metal disks, metallic books and strange scrolls. Cultists and wizards may visit here, but a guardian stops you from leaving with books, even ones you brought. So more recent recognisable books will be here also, not just alien gibberish

6 Prison chamber with sealed pits on the floors, doors all around walls and possibly hatches in the ceiling. A central dais with a console controls all doors. Immortal gibbering mutants are in their cells cry for release. A warden of some kind might maintain the room and the prisoners 

7 Pit chamber with a great dark hole into the deep. Will be a walkway around or over it. A plarform where victims are hurled from. A gong or a horn or bell awakens the pit dweller or its minion. A vast slumbering alien god dwells here with its parasites  

8 Eldritch machine with strange apparatus. May be biological even a creature plumbed into the structure. Room surfaces hum and glow. Several gem control consoles control whatever operates here. Automatons or some devolved former operator might dwell here. Alarms or traps also 

9 Barrier chamber a polygon chamber but all doors are on otherside of a barrier of force, fire or some other threat. Maybe a wall of swarms or thorns. Small hostile creatures may defend the wall

10 Control chamber with hundreds of rows of gem controls. An operator automaton or a devolved resident lives here. A screen may show the complex and inhabitants or looped scenes of prehistory 

11 Forbidden Temple with alien idols and ornate art. Undead robed priests of a cult are here to question if intruders or new cult members.

12 Alien Sarcophagi chamber with some giant alien humanoid. It might be undead like a vampire and hungry if woken up. It will have weird treasures

d12 Eldritch Monolith Feature

1 Observatory with a domed ceiling, and diagrams of hstars on floor. Several control altars can project on the ceiling scenes of the heavens. See the celestial palaces of the star spirits, the heavenly citadel, the world tree, the cosmic mountain, the sun and moon gods in their chariots, selenites being enslaved by gnome troops on the moon, the planetary realms of the great gods and through the great dome into the realm of the outer gods where hungry beings swarm. A guardian of some kind, likely, but living or undead cultists likely too. 

2 Cosmic Egg, a glowing, enigmatic orb or egg is kept secure inside a forcewall or magical field. Might have a vacuum or different gravity inside. Is it s d4 1=doomsday device 2=egg of a kaiju 3=planar communion device 4=vision orb. May have a guardiam or alien wizards or undead cultists working the consoles

3 Genesis device, a great gold cube with a planar language script. Text may grow or the box can float so one person can move it at Mov3 (otherwise it weighs over a ton). If the control grid is tampered with it starts a countdown in alien voices. If opened d4 1=skeltal angels come out to kill all witnesses, then fly into sky forever  2=shoots a 6d6 lightning bolt each round at lawful beings until closed 3=liquid slime and mutagenic spores from abhoth the slime god who will form an avatar in some dark forbidden place to grow, the box held it in stasis. 4=seversal tons of flesh and biological structures grow out per round, smothering any who get close. It is part of Xor a dimension of infinite flesh and hunger who eats worlds. The box is guarded by some monster but the right hand gestures that it will back down. Well you can try and use human limbs anyway

4 Alchemical refinery with huge crystal vats where creatures are grown of kept asleep  for aeons. Some vats and an alien lab can be used for alchemy if you have enough materials. Constructs, golems or slime monsters might lurk here

5 Crystal chamber with crystal structures and surfaces of brilliant glowing consoles. An altar with crystal rods operated the chamber. Crystal sarcophagi for subjects are possible or a marked area of floor might have a marked area or geometric shape in a different colourA guardian or cultists might be here. The controls can use the power of crystals d4 1=open a time bubble for observation, travel, opening stasis boxes or disintegration 2=has banks of sarcophagi to drain humans and make into power gems to operate eldritch technology 3=crystal resurrection chamber 4 = convert organic to crystalline immortal life. Some kind of fuel might also be required

6 Stargate chamber with a coded locked console gate with an iris valve that transports targets to some mysterious location. Often has a guardian caretaker or cultists trying to open it. Controls can define where the gate opens d4 1=ruined alien city under the deep in the dark depths, opening this flooded chamber and starting a countdown to seal the complex 2 = alien monastery above the world with alien beings, possibly with automaton knight bodies in robes. They watch the earth, awaiting a new age of darkness 3=distant jungle temple or pyramid 4=lunar temple ruin

7 Vortex test chamber with alien machines, crystals and brains in vats, with a large inner crystal chamber with two doors to get in. Consoles surround the chamber where a subjects inside can be d4 1=environmental tests (pressure, temperature, atmosphere, temporal fields, mutagenic rays or elemental plane simulations) 2=vortex opens and can be used to observe banished hungry evil beings of the outer darkness and the can see back 3=conjure an elemental node where elemental beings can enter our world and provide energy or raw materials 4=can conjure beings imprisoned in a pocket dimension in stasis through a dimensional vortex

8 Arcane engine with some vast machine with crystals, jars of light, gringing pistons and unearthly noise and vibrations. Control consoles around the room control the machine, which may have automaton or undead workers. An exiled alien or wizard might use this as part of a sheme d4 1=machine that sucks souls and creates underad from victims in hopper 2=produces a shoggoth, slimes or flesh golems from protoplasm vats or throw bodies in hopper to make protoplasm 3=controls environment in the region, with quakes can raise or lower land level, or use weather or make a micro climate over a few miles 4=awakens kaiju across the continant and they start a terraforming process which might include their violent battles or love making

9 Pilot Throne chair on dais reached by stairs. Has control gem grids on arm rests and possibly a crystal helmet. Lesser control stations in niches or a pit surround the throne dais, and a great crystal disk is positioned in front of these. If touched, alien holographic displays flicker on, and the big screen may start. The complex is a star-travelling vessel, and a launch sequence to the moon, or some other world, may be triggered. Doors will close and the vessel will begin to shake as it rises, then accelerates into the void. Concealed niches with guardians might be ready to repel intruders

10 Colossal crypt with a huge ornate black stone sarcophagus weighing tons. A console might help open, revealing a crystal coffin with an alien vampire within who will awaken. It has unusual forms, powers, vermin it can summon and weaknesses to kill. Other ancient alien or planar beings might also be imprisoned

11 Alien sphynx on a dais in the middle of a chamber. It is streamlined and alien. If awakened, its eyes will light up and it will offer knowledge for knowledge. Often has a series of lesser sphynx more like faceless deco gargoyles who will protect the great one. This is a synthetic intelligence that dealt with humanoid minions for the masters and is used to communicate in any language via magic. Some include divination orbs to expand the sphynx range. It might offer quests to find cosmic secrets. Often better informed than most local beings here. It cannot be removed, but it can be destroyed. Some might be blinded. They cannot move but they can cast spells

12 God Prison, a great sealed pit with control consoles. Controls may open the pit for inspections or communication but sets off alarms, flashing lights, and release mist. Using two sets of controls at the same time, you can release the god who will try to eat as many as it can and gate away, leaving a portal behind them. Might be corrupted elemental or slime or living darkness or some more forgotten prehuman demon. Sometimes the bound god is being tormented for resources or magic power

Crystal control altars and you
Control altars have a grid of 2x2 or 4x4 8x8 or 16x16 holes for crystals
Moving crystals tend to alter their current function
Removing them shuts some systems down
Adding can produce obvious results, usually increasing lighting and ambient sound
The more gem slots the more powerful the system
Gems are red green blue yellow red green magenta, and orange
Blear gems are depowered and spent
Black gems are cracked and burned out

d12 Common Crystal FX 2x2 or 4x4

d12 Where do I find crystal control altars or gems
1 Next to doors to open or unlock them, rarer ones are more complex. Used by ancients or wizards who want to impress with old relics they have obtained 
2 Room master controls for environmental settings, including strange light spectra, fog for humidity, heating, cooling and lighting. Larger ones have alien music and voices, and might project images

3 Long empty simple sockets might be on ancient stone monoliths to open concealed doors. Inside will be a chamber larger than is possible, with a more complex control altar inside. 
4 Four sockets in a stone wall, not obvious at all. Reveals secret, invisible, locked doors in a stone wall. Might be a single chamber or a base

5 Old temples may have a control altar hidden with warnings and traps to control local environment

6 On covers that lock metallic books of alien wizards

7 Local tribal leaders might have gems in their ritual dress and items and priests might have a control socket grid on a chest plate or helmet, possibly granting powers. They may know a secret site they use as a treasury or tomb and open seasonally

8 Prehistoric prehuman jewellery sometimes finds its way to collectors or wizards with gems or a control grid that can attach to systems with panels broken or missing but only simple ones

9 Later magic workers may have incorporated them into other devices, you will have to break them to use the gems

10 Might find a grid of gold with gems mixed with ancient treasure or it has been hijacked as a lock for a chest

11 Ancient crashed ornithopters or airships or aether flyers might have gems and panels. Long buried or undersea
12 Certain monstrous species use the gems and grids they hijack the function of. Mostly simple ones

d12 Potion mixing & maxing + can i pee in armour?

Players had a copy of my secret setting notes from here by accident, kinda exposing some stuff, but it's manageable. When I make a setting book, I will have lore split for players and dms to aid this. The party has two more steps to circumnavigate the island. Mostly, they managed to get along with the last few cult towns. This time, they arrived at town, picked fights with mutant-hating bigots, set freak show critters free and burned the building with the corpse of the owner inside in hours. The mayor caught them and said he would not tell as he hated the freakshow. The next evening in next village, they visited a possible wolf witch and on way home by saw a cult ritual in the nice district and attacked, killing the village's hierarchy in one go. I guess they will get its a folk horror Ravenloft domain full of imprisoned jerks soon.

Potions Potions Potions

Old dmg and 2014 have the FX table for mixing potions
Besides d100 so uncommon in dnd5 even more true for players
Maybe dnd and rq evolving away from each other more

One problem is that tables have lots of nothing happens, a waste of time...

d12 Potion Mixing
1 Undrinkable causes vomiting and d4 round helpless
2 Flatulence for d4 hours makes sneaking hard
3 Diarrhoea for d4 hours, stinky and slippery -4 all rolls

4 Hyper acidic melts through the vessel into the earth

5 Lose sense of smell and taste for d4 hours, everything tastes like vomit

6 Causes deafness, if save its temporary for d4 days (bats and other beasts may be blinded)

7 Causes blindness, if save its temporary for d4 days

8 Poison causes painful death or if save loss of half hp and d4 round helpless

9 Explodes 6d6 fireball or 12d6 to the drinker, save for half. If the drinker dies, then the body erupts into chunks and burns others in the area as a 6d6 fireball

10 Mutations d4 minor and one major

11 Polymorphing if you save its temporary for d4 hours and you have your own mind. d6 1=humanoid type or other living species 2=change biological sex 3=slime monster 4=undead 5=shrink to 30cm, not your gear 6=dinosaur

12 Permanant magical property and cosmetic effect, making the drinker a unique being. Might be linked to potion types or something else.

d6 Cosmetic 1=unatural skin and eye colour 2=glows especially during excercise 3=unatural blood and waste colour 4=body has unatural flavour and scent 5= Lose hair or super rapid growth coloured hair 6=semi transperant flesh

d6 Property 1=use one potion power once per day 2=use each potion power once per day 3=no longer age naturally, slows by half 4=no longer require food, water, or to breathe (pick one) 5=regeneration 1hp per round, save each month or cancerous repair error turns you into a shoggoth over a month 6=gain a level 

But what if I buttchug one potion and drink the other?
Buttchugging potions and alchemical supositories take extra d4 rounds to work, so timing hard and bad effects of mixing slower also. It's a bit of a skill; some say it's more potent or lasts longer, but others say it causes liver failure and death if you get it wrong. Best ask old murder hobo experts in a quiet voice. Some say it's just preferred by weirdos.

Obviously, drinking-based healing potions can accidentally drown unconscious patients, so suppositories are safer if you dont have a skilled healer to force-feed healing items. Even a good berry is a choking hazard. Always ask permission before performing first aid. Armour might be a problem for some first aid or applications.

d12 Potion Types
1 Liquid, drinkable, 1 pint or 500ml bottle, dose per bottle, like chugging a beer bottle, round to drink

2 Liquid, drinkable cordial, teaspoon amount in bottle, often with d6 doses, instant if held, easier to give slowly to an unconscious person without drowning them

3 Liquid, splashed on the recipient, some use a holy water sprinkler and can be good vs enemies with some potions. half pint or 250ml bottle

4 Plaster, stick a square of sticky fragrant material on the chest, takes d3 rounds to apply and work. Their are rarer small ones in a small dressing come in a box of 2d4 that can be applied anywhere in one round

5 Pill, swallow, may be in a jar, box or hollow tooth etc. From pea size to unpleasantly large and choking, they taste nasty, instant if held

6 Sweet, soft, tasty candied morsels with some gold or silver foil, instant if held. Sweetmeats, 

7 Lozenge, fruit or aniseed popular flavours, though some weird ones exist, hard lolly takes d4 rounds to suck to activate. Some goblins place in gums before a fight and sometimes recover from unconsciousness a bit better. In jars or paper bags with 2d4. Some with powdered sugar 

8 Cake or cookie, delicious and takes a round to use. Often in a paper bag or luxurious box with several pieces or a whole cake with 6 servings. Tend to go stale, and they take d4 rounds of chewing to work

9 Syringe, may come with a 1-dose loaded syringe or a refillable syringe with a vial with 2d4 doses. Requires a healer or medical skill to rush in a round, not in combat

10 Supository, greasy rectally inserted pellet. Come in jar of box with d3+1, hard to use in combat, takes a d4 rounds to use, best in private on conscious, consensual patients

11 Ointment, applied to skin, takes d3 rounds, dose per jar, 1in6 chance of more concentrated and use less with a d6+1 doses. Takes d3 rounds to apply to work. Some versions are instant, but burn often used in contact poisons or traps. Blade venom might be included too - tales a round to apply and is instant on a hit. A dozen arrows can be applied instead

12 Vapour in a jar to inhale, common ones are 1 pint or 500ml glass bottle, better ones are crystals in a tiny jar you huff with d4+1 doses. Some are used in traps

d12 Discount half price potions with only a few side fx

1 Addictive, most common with healing potions 

2 Take 10 minutes to kick in and half the duration or effect

3 Save each use or throw up, tastes like rotten corpse juice

4 Save each use or take d4 poison or chemical burn damage
5 Makes hair fall out if you fail a save (some make you grow a d4 years of hair)

6 Makes you infertile if you fail a save

7 Diseased if fail a save

8 Reduce a random attribute by -d4 for an hour

9 Half move rate for an hour if fail save

10 Berserk if violence starts, will attack anyone still standing or moving for 2d6 rounds in next hour. After first episode, get a save to resist further incidents

11 See magical faeries and spirits sparkling around you and very distracting when they speak -2 all rolls for d6 hours. Feel numb and tingly

12 The next day their is flora of some kind growing on you. Requires removing the disease or surgery or burning (4d4 damage) to treat. Fungal, vegetal or slime, possibly infectious or spread to bedclothes and garments. When die will grow into a living mass, fertilising the area. Goblins might give to prisoners

.....Oh we only have defective potions left at the moment
Xtra common in goblin markets and dungeon shops or used by cheap monsters

Can I pee in armour? Google said this:
Active Battles: If desperate, knights would pee in their armour. The urine would drain through gaps in the leg armour, leaving the squire to clean the suit later. Adrenaline often suppressed the need to go.

Armour Design: Many suits of plate armour were not fully enclosed at the crotch, often protected only by a "mail skirt" or "faulds" that could be lifted. Later, 15th-16th century armour featured removable "codpieces" or "maille brayettes" (underpants).

Daily Life: Knights typically used toilets (garderobes) before putting on armour, as they rarely wore full plate for long periods.

Hygiene: While urinating was manageable, defecating was more difficult. However, the rear, or "arse" area, was frequently designed to be accessible (using faulds or a "rear culet") for easier movement and to facilitate bathroom needs

Sounds like expensive hitech armour is helpful.
Lots of plate armour was crotchless for ease of horse riding for longer than a joust.

d100 Worst Weird Inn & Guest Rooms

My current map with player exploration of my D&D5.5 game
Yellow is where players been and exploration has been fun
While we had 3 clerics nobody really imvestigated local customs or cults

Chumwater is the home base and helping locals recover from the fish cult
-revived brewing industry and kept inn open

-made deal with goblins for food and defence
-after loss of fishing now locals are farming barley and pigs
-made deal with smugglers guild and getting sea travel
-considering secret land routes of smugglers through tunnels

-------------------------

I dont think i will get anyone commenting, they have had these happen like other posts
not in real life anyhow I hope

These rooms should be only weird rooms in an inn but the effect could affect multiple rooms. A haunted or fairie inn might have several bad rooms. These rooms will be leased out last. Furnishings might be quite fancy and old-fashioned in the manner of old people. Rooms might be run-down and unused or have blood stains. An evil cult run inn might have a few such rooms and will delight in what happens here.

Names of rooms can be simple and relevant but more poetic or litrtary.

I recomend dont just do egytian desert stuff with this (but do that too) try ancient Mederteranean or Iraq or Hitites even India has desert regions.

Desert Ruin
In the south are remnants of ancient kingdoms now deserts. Pockets of the age of Exilon still survive in places, but mostly it is ruins. Locals often shun these places of their ancestors, and zealots will protect them. Others come to rob these places, and tomb-robbing families trace their lineage back to times when the ruins were built. Undead, elemental beings and strange desert spirits may control a complex as a home. Desert factions like bandits, cults or kingdoms might use as a base or to extract treasure.

An expert class for my retroclone?

Desert tomb next - i just had this a while

As our December holiday game has kept going and we are 1/3 way through a karma pool to build a base/nightclub/crime empire run ethically not for profit but keeps us looking wealthy to impress the world of spies, pimps, drug dealers and science villains we deal with. It's not for personal profit we promise. We have super ape accountant on the team to watch the books and make our crime untrackable just like real gov agents and black ops. We just had a moon adventure. Our GM Richard mixing Dr Who and Avengers TV shows of 60s - we met cybernautmen.

All this has given me more time to write rules. I had some ambitious class ideas which need lots of work so Im instead going for more combat and skill based classes as I think modern D&D has too many magic options compared to just skilled humans. So I wanted more classes without magic.

Im open to an alt name suggestions. This is still in the works.

Its based around a theif but not a theif. It is a bit less combat-oriented.
In part it is for NPCs and retired adventurers.

Multiple Classes in my BX based game
In my game, you can change your class several times, then flip between them for level-ups as you please or whichever you used the most. If you start non-human with a species-based class, you can adopt any of the main classes. You can have an extra class per point of INT bonus. I don't recommend it for the magical classes much - even one level in something else makes you possibly a spell level behind a one-class character. I think non-magic classes its less of a problem. A "human" could change their species by taking a species class, but you can only have one species class. My giant class makes lots of changes when they hit 8 feet tall. One level in dwarf and then 4 as a specialist fighter might be pretty good. This expert class will be a common one to split classes with, and many retired adventurers might adopt this. Crossing race as class with class switching and no special species LV cap gets rid of lots of objections i get to BX class as species.

Expert
A class of skilled professionals. Often are storekeepers or traders or inventors or alchemists. In a technological setting, they would include technicians, pilots, medics and scientists. Most start as apprentices or students, then become journeymen or tutors before becoming masters or grandmasters in a trade guild, workshop or school for their profession. The specialists of this class have different skill benefits

3x arms skills - (eg blades, crossbow) +1/3 lv
6x arts skills - (eg Merchant: evaluate, bluff, bargain, streetwise, search) +1/lv

Lv 17-20 x6 or x1/6 or +6

Your multipliers can be used generally on your specialist skill roll to
-reduce material cost 
-reduce task time or make duplicate effects in the same time
-various benefits based on specialisations
-When the multiplier rises to x4 can split it up into two lots of x2 instead
-When the multiplier rises to x6 can split it up into two lots of x3 or three lots of x2 instead

This needs work

But lots of npcs would take it and i can see players taking one level 
this might be more appealing at high level when you do more domain than dungeons
or a level to buff your main class abilities
-wizard to increase research speeds
-thief might do it to boost lock skills 
-dwarf might use to improve crafting or mining skills
-the gun and xbow possibility might be slightly abused for the + to hit - its not so bad
-possibly if i finish my alchemy rules might mesh with this system
-ive considered some other abilities for each subtype or make some new specialist skills they could employ  or have lists like my alchemy skills - abilities like: sharpening +1 damage until first blow on edged weapons (maybe stack to +2 or +3 higher level) 

The gun and xbow thing makes them kinda dangerous as guards, but also weaker than fighters in most cases in the long run.

----------------------

The followers worked ok in playtest - here is what i did with one over 4 levels
This gang with light crossbows would launch impressive volleys

1st Lv - d6hd thug with porter and club skill
2nd lv - d6 crossbow guy 
3rd Lv - 1st lv crossbow guy, other guys go up to 1st lv
4th Lv - 1st lv crossbow buys, others up to 2nd lv

even a 4th lv merchant might like a bunch of goons like this as guards
so a passive main character running armed goons might work well
they could go in the dungeon while main character runs the camp
