Quality

Quality is a stat that improves the signature stats of an equipment or adds additional bonuses to skill gems. Each item type has a currency item associated with it that increases its quality.

Mechanics

Quality can be applied to most equipment (quivers, jewels, and belts are the exceptions). Any item with at least 1% quality will have a Superior prefix when dropped on the ground but not when in the inventory.

Quality effects

Item type	Currency	Effect per % quality
Martial weapons	Blacksmith's Whetstone	1% more Physical Damage
Wands and Staves	Arcanist's Etcher	Currently no known effect [Likely due to a bug]
Sceptres	Arcanist's Etcher	1% more Spirit
Armour (equipment)	Armourer's Scrap	1% more Defence
Amulets and Rings	Catalyst	Varies by catalyst
Flasks	Glassblower's Bauble	1% more Life/Mana Recovery
Charms		1% increased Duration
Skill gems	Gemcutter's Prism	Varies by skill

For Unique items which grant a skill as an implicit, additional quality will also add quality to the attached skill.

Most items which can have quality can have a maximum of 20% quality. Breach Rings can have up to 50% quality. Effects which grant a global increase to gem quality can also exceed this cap.

Quality is multiplicative to affected stats, and is applied after runes and local modifiers.

Amount

The amount of quality given by a quality-increasing currency item depends on the equipment's item level. The higher the item level, the less quality each currency item will give. Gemcutter's Prisms always add 5% to the skill gem.

Corrupting a flask, charm, caster weapon (staff, wand, sceptre), or skill gem may cause it to gain or lose quality, which can cause it to exceed the 20% cap, up to 23%. Support gems cannot have quality added to them.
