End Guide: How to Reach the End and Defeat the Ender Dragon
To get to the end of Minecraft, you'll need to gather a few things first. Once you are prepared, you will enter The End and defeat the Enderdragon.
The Fastest Way to Reach the End
Diamond pickaxe
A diamond pickaxe is number one priority because you'll need it to get obsidian (to get to the Netherworld), but more importantly to get more diamond.
A Nether portal
Once you gather enough obsidian to make a Nether portal, you'll need to go to the Nether. Once there, you'll need to find a fortress made out of nether brick. Inside the fortress, you'll find a Blaze spawn.
Blaze sticks
Here you'll find a Blaze spawn. Do not destroy the spawn, but instead just wait for the Blazes to spawn and kill them until you acquire 6 blaze sticks. Once you get those, you can leave the nether. Quickest and least resource consuming way to kill a blaze is with a snowball.
enderman
You need to kill a couple of Enderman to get Enderpearls, the other half of the recipe for the Eye of Ender. You'll need to get 12 Enderpearls, which are only occasionally dropped by an Enderman.
Find the end portal
Once you make the Eye of Ender or all twelve, you'll need to throw them into the air. They will travel towards the portal. Once you can throw one in the air and it doesn't go anywhere, dig down and you should find a brick fortress containing the End Portal.
The end
Once you find and place 12 Eyes of Ender into The End Portal, you'll be able to enter and fight the Enderdragon. It will also be filled with Enderman and a few tall towers that you'll need to climb to destroy the pinkish block that regenerates the dragons health. Once you destroy all of those, make your way to the middle where you can fight the dragon when he lands. The quickest way to take him out is with enchanted bow and arrows.
Good luck!
