I was inspired by midwinter to see if anyone would be up for a forum challenge? The requirements to encounter the Hand From Floor ghost are quite a slog, but I've made an award and will give rep to anyone who goes to the trouble! I thought experiencing something for the first time in a game we're all familiar with could be fun, even if we've already seen it.
There won't be any rules or deadlines, feel free to join in if you've faced it before (maybe we could decide a name for him?), other than providing a picture to show us your findings. Instructions to find the ghost below:
