{{#ev:youtube|QNw2Jg644yU|300|right|Path Of Exile - Guide - Quality Basics}}
'''Quality''' improves the signature [[stat]] of an [[item]] such as [[physical damage]] on [[weapon]]s and [[evasion]] for evasion [[helmet]]s or adds additional bonuses to [[skill gem]]s.


Quality applies to armor, weapons, flasks, and gems; in short, all equipment aside from belts and jewelry. It always varies from 0% (at which point it is not displayed on the item) to +20%, and each item type has a [[Currency|currency item]] associated with it to increase its quality. Quality can be an extremely important method of improving items, as it does not affect the requirements for using an item or the mana cost of skills.
==Mechanics==
Quality can be applied to most [[equipment]] ([[quiver]]s and [[jewel]]s are the exceptions), as well as [[map]]s and [[strongbox]]es. Any item with at least 1% quality will have a {{c|mod|Superior}} prefix when dropped on the ground but not when in the inventory.


All items are capped at +20% quality and each quality improving item will improve Normal <span style="background:black;color:#C8C8C8;">'''(White)'''</span> items by 5% each, Magic <span style="background:black;color:#8888FF;">'''(Blue)'''</span> items by 2%, and Rare <span style="background:black;color:#FFFF77;">'''(Yellow)'''</span> and Unique <span style="background:black;color:#AF6025;">'''(Orange)'''</span> items by 1%.
Each item type has a [[Currency|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.


The {{il|Orb of Fusing}} and {{il|Jeweller's Orb}} consume all the quality on an item to increase the chances of rolling more sockets/links.<ref>{{cite web|author=Chris|date=June 3, 2013 12:20 PM|title=0.11.0 Patch Notes|url=http://www.pathofexile.com/forum/view-thread/403446#p3578131|publisher=Path of Exile Forum|accessdate=2 July 2013}}</ref>
All items are normally capped at 20% quality and each currency that affect quality will improve:
* {{c|normal|normal}} items by 5%.
* {{c|magic|magic}} items by 2%.
* {{c|rare|rare}} and {{c|unique|unique}} items by 1%.


== Armour ==
Increasing the quality on [[weapon]]s and [[Armour (equipment)|armours]] also makes crafting [[socket]]s and [[link]]s with {{il|Jeweller's Orb|Jeweller's Orbs}} and {{il|Orb of Fusing|Orbs of Fusing}} easier. Each 1% quality improves the result by 1%. This makes obtaining many sockets and links 20% more likely on 20% quality items and even likelier on 30% quality items.


On [[armour]] (helm, chest piece, gloves, boots, and shield), quality increases the [[Armour|Armour rating]], [[Evasion]], or [[Energy Shield]] rating by the listed percentage. As of 1.2, it is additive to the  "% increased" modifier and not multiplicative (change is not in patch notes). Thus, a piece of armour that naturally gives 100 Armour that has a "100% increased armour" [[Prefix]], and a " +50 to maximum armour" [[Prefix]], would now, with +20% quality, give 330 Armour.
Quality is normally capped at 20%. However, there are certain crafting methods that can increase quality beyond that, including:
* Corrupting a [[gem]] or [[flask]] can increase its quality, to up to 23% and 30%, respectively.
* [[Beastcrafting]] recipe for "Corrupt an item with 30% Quality"
* A [[resonator]] with {{il|Perfect Fossil}} socketed, randomizing its quality to 15-30%
* {{il|Tainted Blacksmith's Whetstone}} and {{il|Tainted Armourer's Scrap}} 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%.
* {{il|Ixchel's Temptation}} can have up to 200% quality.
* [[The Necropolis|Necropolis]] crafting can create weapons and armour with up to 30% quality using corpses that add quality to the crafted item.
* {{il|Infused Engineer's Orb}} can increase a [[strongbox]]'s quality to up to 30%. Infused Engineer's Orb no longer drop in game.


(100 {{c|mod|Base Armour}} + 50{{c|mod| Adds Maximum Armour Prefix}})*(1 + 100% {{c|mod|Percentage Increased Armour Prefix}} + 20% {{c|mod|Quality}})=330
===Effect on items===
{{#vardefine:base|100}}
{{#vardefine:added|50}}
{{#vardefine:incr|90}}
{{#vardefine:quality|20}}
The quality is [[stats|summed]] together with other [[local]] {{c|mod|#% increased}} [[stat]]s. For example a piece of armour that naturally gives {{#var:base}} armour that has {{c|mod|+{{#var:added}} to Armour}} and {{c|mod|{{#var:incr}}% increased Armour}} would now, with {{#var:quality}}% quality, give {{Math|display=inline|formula=
        ({{#var:base}} + {{#var:added}}) * (100 + {{#var:incr}} + {{#var:quality}} )/100 =  
{{#expr: ({{#var:base}} + {{#var:added}}) * (100 + {{#var:incr}} + {{#var:quality}} )/100 }}
}}.


 
The table below displays what each category of items and which currency that can increase the quality.
The quality of pieces of armour may be improved with an {{il|Armourer's Scrap}}.
{| class="wikitable"
 
== Weapons ==
Quality [[weapons]] have the average damage '''increased''' with the quality percentage of the base average. Thus, a weapon that normally does 50-100 damage would that has a "100% increased physical damage" [[Prefix]] and a "adds 10-20 physical damage" [[Prefix]], with +20% quality, deals 130-260 damage.
 
(({{c|mod|Base minimum damage}}50 + {{c|mod|Adds physical damage prefix}}10)*(1 + {{c|mod|Percentage increased physical damage prefix}}100%))+({{c|mod|Base minimum damage}}50*{{c|mod|Quality}}20%)=130
 
(({{c|mod|Base maximum damage}}100 + {{c|mod|Adds physical damage prefix}}20)*(1 + {{c|mod|Percentage increased physical damage prefix}}100%))+({{c|mod|Base maximum damage}}100*{{c|mod|Quality}}20%)=260
 
The quality of weapons may be improved with a {{il|Blacksmith's Whetstone}}.
 
== Flasks ==
The amount of health and/or mana restored by a health, mana or hybrid [[flask]] is improved by the quality percentage. Therefore, a flask which normally restores 100 Life and 50 Mana instead restores 120 Life and 60 Mana if it has +20% quality.
 
Utility flasks instead have their duration increased by the quality percentage.
 
The quality of flasks may be improved with a {{il|Glassblower's Bauble}}.
 
== Maps ==
On maps, quality is treated as extra [[Item Quantity|quantity]]. It is added to the quantity from the affixes and suffixes of the map. Maps may be improved with a {{il|Cartographer's Chisel}}.
 
== Skill Gems ==
 
Both [[Skills#Active Skills|active]] and [[Skills#Support Gems|support]] [[Skills#Gems|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.
 
The quality of skill gems may be improved with a {{il|Gemcutter's Prism}}. These upgrades always improve a skill's quality by 1%. Alternatively, a level 20 skill gem and a {{il|Gemcutter's Prism}} can be sold for a level 1 gem with 20% quality.
 
It is possible to get a gems quality above 20% through the use of {{sl|Enhance}} and certain gear allowing up to 44% quality on skill gems (54% if you get both +1 to gems and support gems mods).

==== Dexterity ====
Certain [[Harvest crafting]] crafts can apply [[enchantment]]s on weapons and body armours that could change the effect of quality on that item instead of the default quality (weapon physical damage or body armour defences). This does not affect other aspects of quality such as the chance to have a certain number of sockets or links.


{| class="wikitable sortable" align="center" |
==Skill gems==
!Dexterity Skills
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.

==== Intelligence ====
The quality of skill gems may be improved with a {{il|Gemcutter's Prism}}. These upgrades always improve a skill's quality by 1%. Alternatively, a level 20 non-[[Awakened support gem|awakened]] support gem and a {{il|Gemcutter's Prism}} can be vendored (sold to a NPC) for a level 1 gem with 20% quality.


{| class="wikitable sortable" align="center" |
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 {{c|mod|3% quality}} on a gem with {{c|mod|0.5% effect}} will only grant {{c|mod|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.).

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 Module Error: No results found for item using search term "item_name = Jeweller's Orb" and Module Error: No results found for item using search term "item_name = Orb of Fusing" easier. Each 1% quality improves the result by 1%. This makes obtaining many sockets and links 20% more likely on 20% quality items and even likelier on 30% quality items.

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

  • Corrupting a gem or flask can increase its quality, to up to 23% and 30%, respectively.
  • Beastcrafting recipe for "Corrupt an item with 30% Quality"
  • A resonator with Module Error: No results found for item using search term "item_name = Perfect Fossil" socketed, randomizing its quality to 15-30%
  • Module Error: No results found for item using search term "item_name = Tainted Blacksmith's Whetstone" and Module Error: No results found for item using search term "item_name = Tainted Armourer's Scrap" 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%.
  • Module Error: No results found for item using search term "item_name = Ixchel's Temptation" can have up to 200% quality.
  • Necropolis crafting can create weapons and armour with up to 30% quality using corpses that add quality to the crafted item.
  • Module Error: No results found for item using search term "item_name = Infused Engineer's Orb" can increase a strongbox's quality to up to 30%. Infused Engineer's Orb no longer drop in game.

Effect on items

The quality is summed together with other local #% 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 .

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

Class Currency Increases
Weapons Module Error: No results found for item using search term "item_name = Blacksmith's Whetstone" Physical Damage
Armours Armourer's ScrapArmourer's ScrapStack Size: 40Improves the quality of an armourRight click this item then left click an armour to apply it. Has greater effect on lower-rarity armours. The maximum quality is 20%. Armour / Evasion / Energy Shield
Flasks Module Error: No results found for item using search term "item_name = Glassblower's Bauble", Module Error: No results found for item using search term "item_name = Vaal Orb" Life/Mana recovered or increased the flask duration for utility flasks.
Skill gems Module Error: No results found for item using search term "item_name = Gemcutter's Prism" Depends on gem's specific quality stats
Maps Module Error: No results found for item using search term "item_name = Cartographer's Chisel" Item Quantity
Strongbox Module Error: No results found for item using search term "item_name = Engineer's Orb", Module Error: No results found for item using search term "item_name = Infused Engineer's Orb" Item Quantity; Infused Engineer's Orb also adds certain extra items.
Jewellery Catalysts Depends on catalyst; affects implicit and explicit affixes

Certain Harvest crafting crafts can apply enchantments on weapons and body armours that could change the effect of quality on that item instead of the default quality (weapon physical damage or body armour defences). This does not affect other aspects of quality such as the chance to have a certain number of sockets or links.

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 Module Error: No results found for item using search term "item_name = Gemcutter's Prism". These upgrades always improve a skill's quality by 1%. Alternatively, a level 20 non-awakened support gem and a Module Error: No results found for item using search term "item_name = Gemcutter's Prism" 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%. Module Error: No results found for item using search term "item_name = Enhance Support" and certain gear modifiers can also improve gem quality.
