Affixes are the modifiers on equipment that exist in addition to implicits. They can be present on the item when it is dropped or they can be added and modified later through crafting using shards. The number of affixes on an item often determines its rarity.

Affixes have 7 tiers, with tier 1 being the lowest and tier 7 being the highest. However only tier 1 though 5 can be created through crafting. Tier 6 and 7 affixes must be on the item when it drops.

The values of an affix at each tier fall within a range but the lowest roll of a tier is always higher than the tier below it.

The value an affix has on an item can be re-rolled within its tier using a Rune of Refinement.

Affixes are broken into two main categories: prefixes and suffixes. An item can have up to 2 prefixes and 2 suffixes.

All stats granted by affixes are global. This means the "Increased Physical Damage" affix on a ring will have the same effect as "Increased Physical Damage" on a weapon's implicit or a passive note.
