Quality

Quality is a property of cosmetic items. It is represented in-game by the item's prefix and color.

Quality is a purely cosmetic property, and has no effect on gameplay. Items can have both a Quality and a Rarity value.

Inscribed
Inscribed items have a counter that tracks a specific in-game statistic. A regular item can be changed to Inscribed quality by placing an Inscribed Gem into a socket. Inscribed items can also be unboxed from Treasure Chests. These items come with an Inscribed gem.

Tracked counters are viewable by other players. Other than this, Inscribed items are no different from regular items.
