I think a Jiangshi hero would be really cool. Chinese folklore isn't represented in the game yet at all, so it'd cover some new ground, too. Here's some simple ideas I came up with off the top of my head:
- They'd wield dual pistols. Their arms are too stiff to be anywhere but forward, so it makes sense for both hands to be holding a weapon.
- Some passive ability that incentivizes bunnyhopping, for the monster that's known to hop about on its stiff legs.
- This runs the risk of being very much not fun to play against, but some sort of stamina sapping ability would be thematically fitting. Jiangshi don't typically suck blood like western vampires, but do absorb lifeforce...
- They could be from Chinatown or something rather than actual China, maybe?
