I would like to see a method to unbind items, even if it cost full creation energy and reset the item to level 1. For me it would lessen the cost and pain of trying out new weapons.
★☆☆☆☆: 10 energy
★★☆☆☆: 450 energy
★★★☆☆: 100 energy
★★★★☆: 200 energy
★★★★★: 300 energy
Negative. That ruins the point of binding in the first place.
