The Crimson triangle key is a key found in Daemonheim while training the Dungeoneering skill. It is used to unlock a Crimson triangle door. When picked up, it goes into the Dungeoneering keys interface, and isn't interacted with as an item. Only one crimson triangle key can be found in a single dungeon.
