Indeed, Bloody stumps.

My character has recently had a hand removed at the wrist (Via leto). As it is his left hand, I'm aware that I'm unable to equip two handed weapons, shields, etc. My question now though, is what is the stance on Crossbows?

Feasibly, I could see a person using their fore-arm to level the crossbow, while aiming and shooting, though I thought it best to get DM answers before going along with it.

I don't have a problem with it.

The guy at the dept. of motor vehicles that processed me when I got my license renewed had part of one finger on one hand and a hook for the other hand. He was effiecent at doing my paper work -- he was checking boxes, scribbling notes, and even paper clipping forms together.

I don't have a problem with a shield either. Strap it to your forearm!

Maybe you could even wangle an offhand sickle as a hook!
