Well ...
The new enchant can be applied to pickaxes (only Vanilla) and automaticaly smelts every ore you mine!
Yes, every ore, this mod is compatible with every mod I know, because it checks for smelting recipes, so it will work with every ore with a normal smelting recipe, like I said earlier
You can find the enchant in Desert temples, other Duegons chests and you can normaly get it in an enchanting Table, even if it is very Rare.
