Because of the massive amount of possible seeds, over 8 million seeds in Java Edition that generate portals with 12 eyes of ender are known. The frame has the highest probability of generating with only one eye of ender (37.7%), with probabilities dropping to 28.2% for zero, 23.0% for two, 8.52% for three, 2.13% for four, and a total of 0.433% for five or more. This means there is a one in 1 trillion chance for all 12 end portal frames to contain an eye of ender, activating the portal upon initial generation. Each individual end portal frame block has a 10% chance of containing an eye of ender, as determined by the world seed. A silverfish spawner sits in the staircase. Generation Įnd portals are found within the portal room of a stronghold, hanging horizontally over a pool of lava, with a staircase leading up to the portal. The end portal blocks do not depend on the end portal frame to exist thus, one may create standalone portals with commands or by breaking the frames. This can be achieved by the player standing in the center of the portal area and rotating to place the frames in a ring around them. In order to activate, the end portal frames must be oriented correctly the front face of each portal block must be pointed inward toward the 3×3 portal area. In Creative mode, the player can construct an end portal by placing 12 end portal blocks in a ring enclosing an open 3×3 square and placing an eye of ender in each one.


Eyes of ender cannot be removed from end portal frames. The portal is activated when an eye of ender has been placed in each of the end portal frame blocks, generating 9 end portal blocks within the structure. In Survival mode, the player must venture to a stronghold to activate a pre-existing end portal, as end portal frame blocks cannot be obtained naturally.
