They live in huge caves deep beneath the earth, venturing to the surface only when driven by desperation. If you are delving into caverns and come upon piles of bones near an underground lake, keep a sharp eye out for deep lizardfolk.
A little larger than an average human, the deep lizardfolk are strong, strange, and primitive, even by lizardfolk standards. Each tribe keeps to itself, exhibiting strong xenophobia even towards other deep lizardfolk tribes.
To survive underground, they have tamed several strange creatures that live in the same environment. Each tribe keeps a pit of vipers from which they harvest venom (and sacrifice in gruesome, savage rituals), and their warriors train giant, many-teethed worms that they wrap around their bodies and use to attack their enemies.
To build these, I'm going to take the base lizardfolk and increase its hit points and damage output. I'll also change its attacks so it throws its giant worm instead of its javelin, a potent attack that can continue dealing both piercing and poison damage every round.
Let's do this!
