Flux Crystal

The Flux Crystal is an alternative, but expensive mean of repairing your tools and armor. Throwing it onto an damaged item will repair it over a time of 5 seconds.

 

You can create a Flux Crystal by throwing 64 redstone, a diamond and an emerald together. After use, the Flux Crystal will be destroyed as it has put all of its power into repairing the item. 

 

You can not repair multiple Items with one Flux Crystal!
