I´ve been struggling finding the materials needed for the Crusher, but i got a few Oureclase ores (with diamond pickaxe) so i tried to make a pickaxe and see how it will go. I used it and it was wonderful, every ore i could find was mined, and i mean everyone. This was weird for me so i put some of the best ores in the mod and the Oureclase harvested all of them. The Wiki says it has a Harvest Level 4 but i could mine even Level 6 ores.

(About the Crusher i will made a suggestion next)
