Currency Idea: Exquisite Orb

Exquisite Orb: Upgrade a random suffix or prefix to a tier higher. The item becomes sealed with Exquisite name (just like corruption). After the item is Exquisite, no other Exquisite orb can be used on it.

Exquisite orbs cannot be used on Corrupted items. Players must use the Exquisite orb before using a Vaal orb.

Example: +1 to all projectile skills > Exquisite Orb > +2 to all projectile skills.
