Humans

I feel that the +1 at creation is a bit underwhelming. I think being able to do +2 would make Humans more interesting to play while not being overpowered.

That makes human warriors stronger than dwarves (though also as strong as a transformed weretiger) if put into strength... I think 22 wisdom gives four practice sessions per level (very few races have above 21 wisdom, I imagine this is for balance purposes). 22 dex is okay but not exceptional for rogues so I don't think that's an issue. I don't see anything wrong with 22 int or 22 con from a pure balance perspective.

Just my analytical thoughts off the bat...

Humans at 50 get to kill level 42 players. Thats a pretty big thing.

I think we can do without that change, honestly. Its just a min-maxing suggestion. If you want to go higher stats than 21 you should pick a race that has that plus the balancing drawback. e.g. slith. Literally just look into slith. It seems like it has everything you want. Thank you for posting it though.

Yeah, when is the last time you saw a human unhinge their jaw and swallow a corpse whole?

Ok that made me snort audibly.
