Minecraft wiki entry for End_survival, associated text: Once you make it back to the central island, you have to kill the ender dragon. Pillar up to the towers and block yourself with end stone before punching the crystal in order to reduce damage. Repeat for the other towers. For the caged towers, break the iron bars from under and punch the crystal to reduce damage. Since you don't have a bow and arrows, stand in the exit portal and hit the ender dragon when it perches. Watch out for dragon fireballs and keep attacking until the dragon it dead. Gather all the experience. To get the dragon egg, get a torch from the exit portal and punch the dragon egg so it teleports onto end stone. Mine 2 blocks down from the block next to the dragon egg and break the block 2 blocks under the egg. Place a torch and break the block the egg is on. The egg will drop and you can collect it. Now you can return to the overworld and continue as normal.
