The Item Upgrader in World of Warcraft The War Within introduced Valorstones, and Harbinger Crests as two currencies for upgrading equipment. These can be exchanged at the r NPCs, Cuzolth and Vaskarn. Each item can be upgraded to the highest level for a specific slot once. Upgrades to the slot are less expensive afterward. The pity system, introduced with The War Within, also reduces the extreme variance in upgrades.
