Eldritch Chest

An Eldritch Chest will spawn after defeating Eldritch Ettin in the final level of the Bloodstone Caves dungeon. Each player in the party may open the chest and will receive one item from the drop list in normal mode (2 in hard mode). After the chest has been opened by every player, a countdown timer will begin and the party will be transported outside the dungeon after three minutes.
