After the update of the mage's class advancement, there was an inflation of the material prices in the auction house within the game.
At the same time, there was a new NPC created to assist mage class advancements. It was called the Master of Disintegration.
The conditions for the Five Elements Warlock to undergo class advancement were more special. Players were required to find materials of the five elements and bring them to the Master of Disintegration for disintegration, in exchange for the Points of Five Elements needed for class advancement.
As long as the items corresponded with the elements, the players could obtain the respective Points of Five Elements from the disintegration.
