How do I get the Ender Dragon egg and what does it do?
The dragon egg does absolutely nothing (well, apart from eluding most attempts to pick it up). Put it on your mantelpiece to show them online.
From Minecraft Wiki
To obtain the dragon egg, the player may push it with a piston, detonate it with TNT, or place a torch or slab under the block the egg rests on and then destroy that block so the egg falls onto it. It is possible for the player to hit one while it is still moving to the point it breaks, however this is difficult. Another solution, is that you can start breaking a coinciding block and then scroll over to the egg while holding the break button, in this case you will start breaking the egg instead of it teleporting on contact.
The most helpful way and easiest way should be :
- Break two blocks down next to it.
- Then place a torch two blocks down but this time under the block the egg is on.
- Destroy the blocks separating the torch from the egg so the egg falls down on the torch.
- And Voila! You've got yourself a Dragon Egg!
Place a piston facing the egg, place a lever near the piston, then activate the lever. The egg should drops as an item. I don't know what it does; I think it does nothing.
