Know what I mean by 'black'? If you guessed the ender, you are correct. Now, the first you want to do to wipe out the ender and you'll never have to go back for no atomic reason. Is destroy the glowing blocks on top of every tower, but. Do not look into the enderman eyes, they do half of your health every hit. But the thing is, they're so strong. Because they're allies, they don't like being looked at. So if you look them in the eyes, they'll attack. Even if you HIT them, they will still be allies. So the best thing to do is find the nearest tower face it look down and walk over to it. Now, if you destroy the glowing blocks on top of the towers, you'll meet the ender dragon. Now I hope you have all diamond enchanted highly armor , and a diamond enchanted highly sword , because this thang is not easy to kill like a sheep or a pig . For pete sake. Harder than an enderman, it FLIES for crying out loud. Well to my little weak body it is, you. You, I think not. You guys are stronger than me, for I am just a noob. Now, once you kill this thing. You'll HAVE to pat yourself on the back. And advice of what NOT to do, run, scream, and run towards it. Stay where you are, enchanted highly bow with infinity arrows , and bring a lot of steak . Sorry if I took a chunk of your day making you read this,
Hope it helps!
