I wish to see more crude looking killer charms such as the horse head near the end of current rift.
Charms made of remains like bones, skulls, horns would fit many killers pretty nicely and won't look quite so off, like a souvenir keychain from Walmart.
Also what about having charms somewhere else than on hook? Hanging from some ropes at some spots of the map or maybe on tables, on top of sticks just all throughout the map instead of stuffed on a hook? Makes it feel more like you're on killer's territory.
