Omnisaur + Dungeon Design

 

Was reading about a mistaken dinosaur fossil from a poorly considered assemblage with a triceratops a tyrannosaur and ankylosaurs. Yes, I see the appeal for a seven-year-old and that's cool enough to stat up this mistake.

The image above is my current The Orc Prince Module. I unusually wrote up rooms first and now mapping rooms. I might try some alternate configurations when done and have them as bits a GM could cut out and reassemble or ad to some other map. A strange new kink in my process. A few years ago I barely wrote up any adventures and Patreon got me writing almost a hundred in a few years to some stage. I still consider it all experimental and I'm glad I can still try building these things in new ways. This current process might be good for underestimating the labour of some of my plays with megadungeons that that took double or quadruple the estimated labour. The threefold flyer format and one sheet dungeon pdfs were written to fit. Anyway, I have a recyclable coffin and circle-stairwell-into-a-pit graphics. Broken foot and lungs being manageable but today a reminder of health swings affecting my moods and neediness for interaction. Thanks to ppl leaving comments recently!

Omnisaurus 
Neutral Altered Prehistoric Animal
AC +10 HD 20 Attacks 5 Move 
Bite 3d8 Hornsx2 2d10 Claw x2 d6 Thagomizer 3d10 Plastron Bash 3d6
The dinosaur can vary its attacks each round especially if any attempt to blindside or trap them or to favour unwounded body parts. One option used when closing in the first round is to charge so horns do double damage then taking a nip a claw scratch and a tail thagomiser wack. They are about as smart as a monitor lizard but mostly fearless.

The terrible combination and basic body shape of a t-rex, the spiked plastron and tail thagomizer of an ankylosaur and the horns and shield of a triceratops. Made by some deranged serpent folk wizard in some war, a few eggs can be found in serpent folk cryonic bunkers. Part of a long-forgotten arms race in a war against amphibians long ago. Many Omnisaurs have a clan tattoo of some forgotten faction. Occasionally some have additional modifications or may be ridden by a serpent folk wizard
