Ender dragon

The Ender Dragon is a tough mob, and a hard one to defeat and conquer.

If you do not have armor, and you pass by one, you will most likely die.

It will drop fireballs along the way. It has purple lines if your killing it near a place with End Crystals. You can obtain its head if you have Looting XII or XVIII. The item is very rare, and is normally obtained by having Looting III.
