wow. this is an amazing resource. I'm still going through all the traits, but so far they seem really well-balanced. I like how you've created traits that are less binary than typical monster abilities (i.e. having a tail instead of legs making it easier to stand up from prone rather than simply being immune to tripping. I too love tinkering with homebrew races, and I can't wait to try some of these traits out. Definitely yoinking backwards strike with a tail for my dragonfolk race. :)

I'll probably come back with more notes, but the only thing that's stuck out to me thus far is that the bioelectrogenesis offensive trait talks about using electricity to stun creatures, but the ability doesn't actually allow any stunning, merely dealing eletricity damage. maybe a separate trait to stun along with the damage could be included?
