I remember when I first saw Graham. I was so excited that I immediately homebrewed him into my D&D campaign as a playable human subrace. I felt so hopeful that one day we could genetically engineer ourselves into something as cool as Graham.
I don’t think this was the intended reaction.
Basically imagine if a tabaxi and a dwarf had a baby. +3 con as its only modifier, the tabaxi’s lunge but only as a reaction, +1 to AC unless wearing heavy armor.
