There are fearsome devils that are known to kill a person if met. Burning them is good to kill them, but oddly enough,they wear armor. You can use arrows and you can then loot a helmet, a armor, and a belt(For sale?). The ghost wear a santa hat, but can phase through people to evade attacks. The best way to get a dead ghost is when they de-phase and talk to devils about mischeif and when it doesn't notice, use a catapult rock at him!
