With this mod you can replicate the dragon egg for further usage such as decoration, other mods or whatever you can think of.
Requires Minecraft 1.7.10 with Forge 10.13.4.1517+
Also visit the Minecraft Forum for more information.
You start off by crafting the Dragon Egg Replicator:
The second recipe is the Measuring Device:
The Measuring Device can be used for measuring the replication progress.
It tells you how far the progress is done.
Place the Dragon Egg Replicator block on top of Endstone and the vanilla dragon egg on top of the Replicator and power the it.
Take a look at the screenshots for the setup and what how much damage a replication process can cause.
If you want to expose your Dragon Eggs or want them not to teleport but to play the Ender Dragons roar sound when right clicked you should craft the fancy Pedestal:
When you put the Dragon Egg on top of it, the Pedestal will turn it into the Trophy Egg (which can be dyed by right clicking it with a dye).
The material used for crafting is purely for decorative reasons and does not influence the function at all.
How to reignite the magical spark that makes the Dragon Egg teleport again (transform it back to the vanilla Dragon Egg)?
Put into a furnace ;)
