Affixes

Affixes are special attributes that can randomly generate on Gear items, making them more powerful or giving them utility.

Affix Generation Mechanics
Not all affixes can generate on all items. Several properties possessed by these affixes restrict what items can generate with them: These restrictions do not apply to the guaranteed affixes of Legendary Items, which are generated after all other affixes. As a result, Legendary items often have combinations of affixes that are unobtainable on other kinds of items.
 * Item Class Restriction (Item Class): If assigned, has a value of either 0, 1, 2, or 3.
 * 0: Affix can only appear on Weapons
 * 1: Affix can only appear on Skills
 * 2: Affix can only appear on Weapons and Skills
 * 3: Affix can only appear on Amulets
 * Required Tags: A given affix can only appear on items with all of the required tags.
 * Forbidden Tags: A given affix can only appear on items with none of the forbidden tags.
 * Forbidden Affixes: A given affix can only appear on items that have not already generated any of the forbidden affixes.
 * Forbidden Items: A given affix cannot appear on forbidden items.
 * Cost Impact: A given affix will increase the price of the item, by a percentage of its base price.
 * Chance: A given affix has a certain relative chance to appear. The percentage depends on the chance of the specific affix (x) and the chance of all other possible affixes (y), the calculation is x &divide; y &times; 100.

Stat-Boosting Affixes
Stat-boosting affixes are the only affixes that can be applied multiple times to the same item. Only present on Amulets, they grant Stats to the player while these are equipped. The effects bestowed by these stats are listed just underneath the white text in the item's tooltip.

Minor Affixes
Minor affixes are written in green text. The number of minor affixes on an item is limited only by the affix cap imposed by its gear level.

Major Affixes
Major affixes grant powerful effects. A single item may only have one major affix generated normally, except in some special cases like Legendary items. These rare affixes have either a star, a skull with a multiplier (Double/Quad Damage), or a blood drop (Leech) in front of them.

Legendary Affixes
These Legendary Affixes are affixes that can only appear on Legendary Items. Each is assigned to specific items for their legendary variant and can't be removed or changed.

These are the affixes that appear on both legendary items and even as minor & major affixes on normal items:

Removed Affixes
These affixes have been removed from the game.

Trivia

 * The "Can break shields" affix has several inconsistencies:
 * It cannot break physical shields on some enemies, such as the Ground Shaker, Shieldbearer and Oven Knight, nor could it bypass the contact damage from striking a Thorny in the back. However, as it cannot legitimately spawn on other weapons, this can only be seen through modding.
 * The only shield it is capable of breaking is the force field surrounding the King in the Throne Room.
 * It is, however, capable of damaging enemies through force fields, reinforced by the fact that its internal name is "Ignore Global Shield", while "Global Shield" is the alias of the force field status effect.
