I have a server and the Ender dragon has been defeated. However, returning to The End does not respawn the Ender Dragon. How can I get the final boss back on a vanilla server without using mods?
Minecraft 1.9 and higher
To respawn the Ender Dragon, you must craft 4 End Crystals:
Place them around the End portal like so:
A respawning sequence will begin, refreshing the obsidian towers and original ender crystals, and then the dragon is spawned above the portal.
Minecraft 1.8 and lower
Most servers I've seen just reset the whole dimension by deleting the
DIM1 (vanilla) or
world_the_end (CraftBukkit) folder.
There is another way to respawn the Ender dragon, that will keep the player builds in The End, but it is a bit more complicated:
You need an NBT editor (like NBT Explorer). You need to open
DIM1\r.0.0.mca and edit in
Chunk [0, 0] the
TerrainPopulated property to
When the chunk is loaded again, the dragon will be re-created. Note that this will also re-create the obsidian tower(s) in that (0, 0) chunk. Also note that when you kill the new dragon, a new exit portal with a new dragon egg will be created – you may want to switch to creative to remove the unnecessary ones.
It can be done from in game with the WorldEdit plugin (which most servers do), without needing to delete the
-dim 1 folder, and therefore preserving any structure you built away from the main platform in the End.
It's rather easy:
- Go through the end portal.
- Left click on one corner of the end platform
- Go to opposite corner (at least 200m away) and make a pile of blocks roughly 20 high
- Right click top block on your pile
And poof, everything in that entire area is as it original was. Hurry and
/spawn before the dragon can generate and it wont even be there until a new player comes through the portal.
In vanilla Minecraft, spawning in an Ender Dragon Egg won't work:
You can get a plain white spawn egg that reads Spawn Ender Dragon by typing /give [player] 383 1 63, which is the item ID. However, when you try to spawn it, you cannot and it does not really work as anything.

Instead, you can use EnderSpawn - a server plugin that allows you to easily respawn the Ender Dragon, without having to regenerate the End and lose any player constructions.
