The Enigmatic hoardstalker gives the player a riddle and the player must present an item to him to complete the riddle. If you give it the wrong item, you will receive some damage. Give it the right item and the doors will unlock. Every item used to answer the riddles can be found in the same room: either on the floor, on the table, in the chest, or in the barrel. The items in the room all have (o) in the name and have a destroy option. You must have a certain Summoning level to understand him, although you can still complete the challenge by random guessing.
Without me, a deathslinger is merely a gorajo with a stick.
