The End (1.21.1)

Eyes of ender

• Eye of ender = 1 ender pearl + 1 blaze powder. Pearls come from endermen (0-1 each; densest in warped forests) and piglin bartering; blaze powder from blaze rods (1 rod → 2 powder).
• Thrown, an eye flies a short way toward the nearest stronghold and then drops back as an item or shatters (20% chance).
• Filling a portal takes 12 eyes at most; each frame generates with an eye already in it 10% of the time (1.2 on average).

Strongholds

• 128 per world, in 8 rings around the world origin (0, 0). The innermost ring has 3 strongholds between 1280 and 2816 blocks from the origin; the next has 6 at 4352-5888.
• Underground, usually around Y 0 to 50, built of stone bricks with mossy and cracked variants; corridors, iron doors with buttons, prison cells, libraries (chests with enchanted books and paper), and store rooms.
• The portal room is never next to the entrance staircase. It holds the 12 end portal frames around a 3x3 hole, a pool of lava under the frame, and a silverfish spawner on the stairs.
• Portal frames cannot be broken in survival, and an eye placed in a frame cannot be taken back. The 12th eye activates the portal.

Arriving in the End

• Entering the End portal is one way: the way back is the exit portal after the dragon dies, or dying.
• You arrive on a small obsidian platform at about (100, 48, 0), often in the void off the edge of the central island. The central island is end stone, its surface around Y 60.
• The void is under everything; falling off any edge is certain death and the items are lost.
• Beds explode here as in the Nether. Endermen are everywhere: looking one in the face angers it.

The central island

• 10 obsidian pillars stand in a ring around (0, 0), 76 to 103 blocks tall. Each carries an end crystal; 2 of them are inside iron-bar cages — those on the second and third shortest pillars (79 and 82 blocks). Pillar heights go up in steps of 3, thicker pillars being taller.
• The exit portal is the bedrock fountain at (0, 0); it is inactive until the dragon dies.

End crystals

• An end crystal heals the dragon by 1 HP every 0.5 s while it is close (a white beam joins them). Destroying a crystal while it is healing the dragon deals 10 damage to the dragon.
• Any hit, arrow or explosion destroys a crystal and makes it explode — stronger than a creeper and deadly up close. Caged crystals have to be uncaged (or hit through the bars from the right angle) first.

The ender dragon

• It circles the island, dives at players, and perches on the exit portal fountain from time to time — more often the fewer crystals are left (chance 1 in 3 + crystals alive). While perched it breathes and can be hit in the head from the ground.
• While it flies, arrows hit it (the head takes full damage). While it is perched, arrows and wind charges bounce off it (arrows catch fire); melee hits land.
• It destroys most blocks it flies through, except obsidian, end stone, bedrock, iron bars and end portal blocks.
• Explosions hurt it normally, which is why beds (which explode in the End) are used against the perched dragon.

After the kill

• Its death opens the exit portal (back to the overworld spawn or bed) and leaves the dragon egg on top of the fountain. The egg teleports when hit; it is collected by letting it fall onto a torch or by piston.
• The first kill gives 12000 experience.
• An end gateway appears 96 blocks from the centre at Y 75: a 1-block bedrock opening that teleports to the outer islands about 1000 blocks away (usually entered by throwing an ender pearl into it). Each later kill adds another gateway.
• The dragon can be summoned again by placing 4 end crystals on the edges of the exit portal.

Outer islands

• End stone islands with chorus plants (chorus fruit teleports the eater; popped chorus fruit makes purpur blocks).
• End cities: purpur towers guarded by shulkers (30 HP, Levitation bullets). Their chests hold diamond and iron gear (often enchanted), and an end ship beside some cities carries the elytra and a dragon head.
• The space between islands is void; crossing it needs bridging or ender pearls.
