When I watch people on videos say 'I don't think going to the End City is worth it', I thought I should make the End City better by adding some Ender tools. Here's how you get them:
Go to the End City and find the End Ship. Then go to the place you would find the Elytra. Then in the same chest you would find the Elytra will be a set of Ender tools and Ender armor (not an Ender bow and arrow).
The Ender tools and armor will never break and you can wear the Elytra with a Ender chest plate on.
The Ender sword does 15 damage points and knocks back enemies the same amount as the enchantment knock back 5 would.
The Ender pick axe is the only thing in Minecraft that can mine bedrock.
The Ender axe chops wood blocks as fast as a diamond pick axe would mine stone.
The Ender shovel digs up dirt blocks as fast as a diamond shovel with efficiency 5 mines dirt.
And finally, the Ender armor. If an enemy hits you while you are wearing any piece of the Ender armor, they will take as much as damage as the armor protects you (the helmet protects you the same as a full suit of iron armor would. The chest plate protects you as much as a full suit of diamond armor enchanted with protection 1 would. The leggings protect you as much as a full suit of diamond armor would. The boots protect you as much as a full suit of chainmail armor would).
