d100 Subterranean Mutations

So veins touches on this topic a bit but I had envisaged stuff like this before to turn creatures and humanoids into subterranean versions.

Some great stuff here for Veins on where do underworld folk get food, including gating to poor Xor and eating it....crossover!

As some mutations here explain many creatures in underland have adaptions to reduce needs for air and food and water. No luck for visitors though. Squeezing is mentioned too as a adaption to moving in confined spaces. A well evolved underdweller will become worm like and can burrow through earth able to breathe.

Mutations so Far
Xor Bio Mutations
Necro Mutations
Reptilian Mutations
Diabolic Mutations
Plant Mutations
Faerie Mutations
Mental Mutations
Third Stage Mutations
Law Mutations (to be revised under current mutation style)

errata at bottom of this post also as first two never got taint source tables

d12 Sources of mental mutation
1 Subterranean ancestor tainted bloodline
2 Exposed to strange radiations from illuminated caverns
3 Contaminated by fungi spores
4 Contaminated by strange food of the deep
5 Strange parasites entered body triggering change
6 Exposed to disease from the deep
6 Supernatural radiance of strange crystals

7 Poisoned by trans uranic elements and strange metals
8 Curse of the deep gods on you for transpression
9 Malnutrition and light deprivation triggers strange change
10 Venom of some creature triggered changes
11 Ancestors spent a era as cave dwellers
12 Dark elves want to help you survive in the deep and use dark pixie dust on you

d10 basic types
1 Facial/sensory
2 Skin
3 Torso/body
4 Abdomen
5 Arms/manipulation
6 Legs/locomotion
7 Mouth
8 Cranium/skull
9 Organs
10 Brain

This was handy for this and for my upcoming d100 parasite post

Previous Mutation Errata

7 Biological weapon deployed
8 Biological weapon contaminated location long ago
9 Wicked person contaminated you deliberately via food
10 Had a contaminated lover
