Hi everyone. The new Elytra tutorial world has made the prep work for this quite a bit easier, so here's the walkthrough for that world.
I'm making this super-user friendly for those of you who have never tried this and have no clue what you're in for. It's lots of fun.
----------------------------------------------
EDIT: The following workaround may have been patched. Which would suck. A lot.
EDIT REDUX: As of 6-22-2017, this appears to have not been patched. See comments. :-)
----------------------------------------------
First of all, make sure you are not playing on Peaceful. Then,
GET AS MANY MATERIALS AS YOU CAN AS SOON AS YOU START THE TUTORIAL. At the beginning of the tutorial, you can take materials from chests, go to other tutorials areas and back... and many of the mats are magically refilled! You're going to need many of these for other achievements anyway, and Blaze Powder is now necessary for all potions. So stock up... NOW.
As has been stated, you need an Ender Portal... and a lot of prep. You're going to need the full 12 Eyes of Ender for this portal.
Don't store your items in any chests lying around. What I did was make a new large chest near the bed area, which I made as my home base.
Some advice:
=> In the Enchanting Area, there's a chest with a Diamond sword in it. You can enchant it with Fire Aspect II to burn lots of enemies, and Endermen.
=> There are a LOT of Diamonds around. Get an iron pickaxe and go to town. Go to the underground beacon and tear it apart. Make yourself a full set of Diamond armor. And swords. And pickaxes. A bunch. Makes life easier.
=> Get lots of Emeralds. You'll need them to trade with the villagers.
=> Get gold, too. You get make Notch Apples with them. Those are helpful, and there's a LOT of gold in them there blocks. Climb the towers and hack away. If they fall, just grab them from the bottom of the towers.
---------------------------------------------------
Now for the fun part.
Eyes of Ender are made from an Ender Pearl and Blaze Powder.
Blaze Powder - Again, you'll need 12 of these, so abuse the material respawn in the brewing tutorial area. A lot. You'll also need Ghast Tears, Nether Warts, and Magma Cream for other stuff, so grab those now. Better to get these now than having to travel to the Nether at all.
Ender Pearls can be obtained one of two ways:
The Hard Way - Kill lots of Endermen. I've seen them spawn pretty regularly near the tutorial village or just outside. You'll need AT LEAST 17 Ender Pearls in total. That's a lot of Endermen. 12 for your Eyes, 4 more for your End Crystals, and (if you want) 1 more for this achievement
The Easy Way - Follow the tutorial cart track west of the base to a village. Find the villager in purple. Trade a bunch of gold for an emerald. Back out. Trade emeralds for other stuff. You have to level the villager up to the point that he has Ender Pearls. Then you can get a bunch. If he runs out, quit out and talk to him again. You're going to need AT LEAST 17 of them. See why the Emeralds came in handy?
Combine an Ender Pearl with a Blaze Powder for one Eye of Ender, and repeat for a total of 16 of them.
-----------------------------------------------
You also need 4 End Crystals for
Might as well get it now.
End Crystals are made from 7 glass blocks, 1 Eye of Ender, and 1 Ghast Tear, and you need 4 of them. Go to where you initially spawned and dig up all the dirt, then bake all of it in a furnace until you have 28 glass blocks. Then use the Eyes of Ender and Ghast Tears for a total of 4 End Crystals.
-----------------------------------------------
Now the REALLY fun part. Enchant your weapons, your swords (fire doesn't do much to the dragon, but it helps against others, so, yes, make a few different diamond swords). Also have a bow and lots of arrows handy. That means lots of skeletons (which aren't hard to find, or feathers and flint to make your own. You're going to want a bunch. Oh, and health potions. And food. And maybe a crafting table and furnace.
Leave your last Ender Pearl at home, (or use it for the Beam Me Up achievement first).
Take an empty bottle. That way you can get this later:
Now you have to go to the End Portal. Luckily you basically can avoid the Nether altogether (unless you need it for other achievements).
Go to the following spot on your map, and
SAVE YOUR GAME. This is super important. Don't make a save later because there's a possibility that after everything you're about to do, you can't destroy the End Crystals. In that case, you're going to need to exit without saving, quit out of the game and go into options. Then you'll have to "Reset the End" before you can actually beat the Ender Dragon. Which is very annoying. In any case, go here:
X: 209, Y: 65, Z: 89This is the entrance to a VERY deep cavern... with a pool of water at the bottom. If you're ready, take a deep breath... and jump into the water. You won't take any damage. Now climb up to the lit building. You'll run into a bunch of skeletons and creepers to make your life more fun.
Then when you break into the building, there are silverfish! Where the hell did THEY come from?? To avoid them, I used dirt blocks to make a high path to the portal, and then blocks in front of their spawn next to the portal. Even so, you're going to want to hurry...while avoiding that lava. Fun!
Place an Eye of Ender in each of the 12 spots on the portal. Make sure not to accidentally throw one. You'll need to reload. Once you've done that, voila! An End Portal! And you'll get this if you don't have it:
You're now in a room. The trick is that you are about 10 blocks BELOW the surface. Start digging up, and try to make a staircase for a quick escape if you need it. Oh yeah, and there's an Obsidian floor. Dig it up.
I've been told you can do this on Peaceful, which eliminates the Endermen on the surface. Otherwise, the place crawls with them. Your fire sword will come in handy.
To kill the Dragon, you need to destroy the crystals on the tower, or else it'll keep regenerating. You can shoot them, or you can use dirt to climb the towers and hack that way. Be warned, they explode when destroyed.
Once you've destroyed them, go to town on the Dragon. One suggestion is to make a small Obsidian wall to hide behind with the Obsidian you dug up downstairs.
Once the Dragon is dead, there will be an Exit Portal.
DON'T GO THROUGH IT. Instead, take those 4 End Crystals and place them around the portal. You want them in the middle blocks of the 3-part segments of the portal, not the single segments. Once you do that... HOLY CRAP, it's another Ender Dragon!!
Kill it if you want, or sacrifice all the stuff you have and just die. Go back to the Outerworld, and you'll have killed a lot of very difficult birds in one fell swoop.
Best of luck!!
