End Portal Frame

An End portal frame is an indestructible block, 12 of which form an End portal. Eyes of ender must be inserted into all 12 empty frames (if not already present upon generation) for the portal to activate and allow passage into the End dimension.

End portal frames, like bedrock, are unobtainable and unbreakable in Survival or Adventure mode. It can be obtained only by accessing the creative inventory or commands.

12 End portal frames generate naturally to form the End portal in each stronghold End portal room, over a pool of lava with a staircase containing a silverfish monster spawner. The frames generate in a 5×5 square formation, with 3 frames on each side, without the corners. Each End portal frame generates facing inward, with a 10% chance of containing an eye of ender.
