Atziri's Orb

Allows you to modify corrupted items. Must be used before corruption. Preferably recipe only:
1 Mirror of Kalandra + 1 Vaal Orb = 1-2x Atziri's Orb

Would allow continuous eternal-vaal of stuff like 6l legacy shavs, idk if it would be unbalanced or not, that's why i set the idea of an extreme price.
