would be a cool idea if you could cut down the hanging skeletons/wights and they could have a chance to come back from the dead and attack the player.
Maybe make it reanimate a couple of seconds after being cut down to jumpscare new players.
Another idea of mines is there could be a potion you can throw at the corpses of wights/skeletons and they would reanimate, expec they wont attack the player and instead attack enemies/roam (example dragging a dead wright into a boss room and throwing the potion, causing it to reanimate and attack the boss)
