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

Modifier Generation Mechanics
Not all modifiers can generate on all items. Several properties possessed by these modifiers restrict what items can generate with them: These restrictions do not apply to the guaranteed modifiers of Legendary Items, which are generated after all other modifiers. As a result, Legendary items often have combinations of modifiers which 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: Modifier can only appear on Weapons
 * 1: Modifier can only appear on Skills
 * 2: Modifier can only appear on Weapons and Skills
 * 3: Modifier can only appear on Amulets
 * Required Tags: A given modifier can only appear on items with all of the required tags.
 * Forbidden Tags: A given modifier can only appear on items with none of the forbidden tags.
 * Forbidden Modifiers: A given modifier can only appear on items which have not already generated with any of the forbidden modifiers.
 * Forbidden Items: A given modifier cannot appear on forbidden items.

Stat-Boosting Modifiers
Stat-boosting modifiers are the only modifiers which can be applied multiple times to the same item. Only present on Amulets as well as on "++" and "S" Weapons and Skills, they grant Stats to the player while these items are equipped. The effects bestowed by these stats are listed just underneath the white text in the item's tooltip. Note: A given item can only generate with stat-boosting modifiers corresponding to that item's base scaling stats (e.g. most Shields cannot generate with Brutality Up because their damage only scales with Survival).

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

Major Modifiers
Major modifiers grant powerful effects. A single item may only have one major modifier generate normally, except in some special cases like Legendary items. These rare modifiers have a star in front of them.
