If you need something, please let me know.
Weapons and armor can be enhanced beyond Grade A for top-grade items and specialized for PvP. Weapons must have bestowed special abilities... Once it is enhanced, an item can only be used by its owner.
And once a multi-user item is specialized, you can use enhanced Spellbooks, but you cannot augment, soul crystalize or convert it. Be careful so that you don't have to cancel the effect.

Enhance weapons and armor for PvP.
Cancel enhancement.
Obtain consumable item.
