Path Of Exile - Guide - Quality Basics

Quality improves the signature stat of an item such as physical damage on weapons and evasion for evasion helmets.

Mechanics

Quality can be applied to most equipments and strongboxes aside from amulets, rings, belts, quivers and jewels. Any item with at least 1% quality will have a Superior prefix when dropped on the ground but not when in the inventory.

Each item type has a currency item associated with it that increases its quality. Quality does not affect the requirements for using an item or the mana cost of skills.

All items are normally capped at 20% quality and each currency that affect quality will improve:

• normal items by 5%.
• magic items by 2%.
• rare and unique items by 1%.

Increasing the quality on equipment also makes crafting sockets and links with Jeweller's OrbJeweller's OrbStack Size: 20Reforges the number of sockets on an itemRight click this item then left click a socketed item to apply it.

Effect on items

The quality is summed together with other increased stats. For example a piece of armour that naturally gives 100 armour that has +50 to Armour and 90% increased Armour would now, with 20% quality, give ${\textstyle \color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}(100+50)*(100+90+20)/100=315}$.

The table below displays what each category of items and which currency that can increase the quality.

Skill gems

Both active and support skill gems may have quality. Every skill is affected by quality differently, but frequently it somehow improves the damage dealt with the skill. Buffs and curses, obviously, do not have their damage improved. Even those that do have their damage improved will see different rates of improvement for a given amount of quality.
