Prismatic Chest

The Prismatic Chest is the end chest of the Ooze Pit dungeon and will spawn when the 3 Prismatic Oozes and the 2 Hulking Volatile Oozes that each spawns are slain. Each player in the party may open the chest and will receive one Prismatic Gelatinous Material, as well as 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.
