Minecraft wiki entry for Combat, associated text: Ender dragons spawn naturally (when the player enters the End the first time) or can be respawned with 4 end crystals on the exit portal and have extremely high health (100 hearts). They can only be found legitimately in the End. Always craft at least some diamond armor and bring at least a diamond sword, as well as a Power V and Infinity bow. Instead of bringing a helmet, bring a pumpkin instead, as there are lots of endermen and the pumpkin will stop them from becoming hostile when looked at. Also, bring at least 5 golden apples, at least three extended invisibility potions, and a water bucket or a hay bale. A tactic to fight one is to stock up on ladders, as there are obsidian pillars with end crystals on top. However, when the end crystals are destroyed they blow up, and the diameter of the explosion is larger than the pillar, causing the player to fall off. It would be a better idea to mine lots and lots of obsidian or end stone so that the player can make their own pillars and shoot the end crystals from a distance. That way, the player won't fall off and die. Coming unprepared will most likely result in their death (if the player dies in the End, they would spawn like normal in their default spawn point).
