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 or adds additional bonuses to skill gems.

Mechanics

Quality can be applied to most equipment (quivers and jewels are the exceptions), as well as maps and strongboxes. 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 weapons and armours also makes crafting sockets and links with Jeweller's OrbsJeweller's OrbStack Size: 20Reforges the number of sockets on an itemRight click this item then left click a socketed item to apply it.

Quality is normally capped at 20%. However, there are certain crafting methods that can increase quality beyond that, including:

  Shift click to unstack. randomly sets a corrupted equipment's quality to 0-29%
• Monsters of magic or rare rarity and some chests (e.g. Delve, Heist) can drop items with quality higher than 20.

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 ${\textstyle \color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}(100+50)*(100+90+20)/100=315}$.

Skill gems

Both skill gems and support gems may have quality. Every skill is affected by quality differently, but it frequently improves the damage dealt with the skill or provides small improvements like increased Area of Effect. Even those that do have their damage improved will see different improvement rates for a given amount of quality.

The quality of skill gems may be improved with a Gemcutter's PrismGemcutter's PrismStack Size: 20Improves the quality of a gemRight click this item then left click a gem to apply it. The maximum quality is 20%.
Shift click to unstack.. These upgrades always improve a skill's quality by 1%. Alternatively, a level 20 skill gem and a Gemcutter's PrismGemcutter's PrismStack Size: 20Improves the quality of a gemRight click this item then left click a gem to apply it. The maximum quality is 20%.
Shift click to unstack. can be vendored (sold to a NPC) for a level 1 gem with 20% quality.

The effect of quality scales with the base quality effect, however, only whole numbers will be granted (and thus the effect will always be rounded down); for example 3% quality on a gem with 0.5% effect will only grant 1% effect and not 1.5% effect. Effects with some degree of fractions are rounded to their natural bases (i.e. seconds will be rounded to milliseconds, etc.).

It is possible to get a gem's quality above 20%. Corrupting a gem can increase its quality by up to 23%. Enhance SupportEnhance SupportExceptional, Support

Place into an item socket connected to a socket containing the Active Skill Gem you wish to augment. Right click to remove from a socket. and certain gear modifiers can also improve gem quality.

Alternate Quality

It is possible to change the quality of a gem to provide a different effect.

There are currently four types of quality:

• Superior (normal quality)
• Anomalous
• Divergent
• Phantasmal

Most gems do not have all four types of quality.

Skill gems with alternate quality effects can be found in Grand Heists. A Prime Regrading LensPrime Regrading LensStack Size: 20Change the type of quality of a skill gem with quality to another random qualityRight click this item then left click a skill gem to apply it.

Version	Changes
2.2.0	When you use an Orb of Fusing or a Jeweller's Orb on an item, the item's quality is no longer consumed. The way that quality affects the result has also been changed. Each 1% quality improves the result by 1%. This makes the Fusing process 20% easier on 20% quality items, for example.
