Changes

I'm not sure how sacrificing keys work but I feel this page needs editing. Before, it said you could only sacrifice a key if you sacrifice a lock(presumably the lock for the key), however as I was sacrificing 4 lead lumps with 9 keys in the alter, I ended up with 1 key left. Also sacrificed 16 keys with 1 oar and 1 pig fat, ended up with 3 keys.
