Ender Key

The Ender Key is the item that allows the player to enter the end. Upon receiving the Ender Key, it will be consumed and grant you access to the use of Ender Eyes in the End Portal Frames. Attempting to light the End Portal without the Ender Key will result in the consumption and permanent deletion of however many Ender Eyes you use. The Ender Key is crafted with the Adamant Ingot, Neptunium Crystal, and Ichor Emblem at a Haven Altar.
