Modifiers

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:

• 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.

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.

Stat-Boosting Modifiers

Stat-boosting modifiers are the only modifiers which can be applied multiple times to the same item. Only present on Amulets and the Hunter's Grenade, 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.
