Any weapon or armor piece can receive a quality modifier, regardless of that item's rarity. It can have a value of between 0% and +20%, although if the value is 0% the quality is not listed since it has no effect. Quality is separate from magical affixes, and is grouped with the item's normal stats.
- On weapons, quality increases the base damage of the item.
- On armour, quality increases the item's armour, evasion, and energy shield.
Changing an item's quality
There are two consumable items that can change an item's quality. Whetstones increase the quality of a weapon by a few percent, while Armour Shards increase the quality of a piece of armour. These consumables cannot raise an item's quality higher than 20%.
