Item generation and crafting

Item Level

Item level, usually written as iLvl, determines which modifier families and tiers can appear on modifiable equipment. It is separate from the level required to equip an item.

A higher item level unlocks stronger modifier tiers, but it does not guarantee those tiers and does not remove the lower eligible tiers from an ordinary crafting pool.

How item level affects crafting

Eligible modifier pool
  1. Choose the base.The item class and exact base determine which modifier table applies.
  2. Check item level.Every modifier tier has a minimum item level. Tiers above the item level cannot roll.
  3. Keep lower tiers.Unlocking a stronger tier does not remove the weaker tiers already eligible in an ordinary roll.
  4. Apply restrictions.Rarity, open prefix and suffix slots, existing modifier groups, currency rules and special crafting systems further change the pool.

Item level, required level and drop level

Different values

Item level

Controls affix and tier eligibility on modifiable items. It usually comes from the area and monster level that produced the item.

Required level

Controls whether a character can equip the item. For equipment it is based on the base and the affixes currently present.

Drop level

Sets the minimum area or monster level at which a base item becomes eligible to drop.

Important exceptions and breakpoints

Current rules

Map monster levels can stack

Irradiated grants +1 monster level. A relevant Coalesced Corruption or Cleansed map modifier can add another +1.

Exceptional items

With the required Atlas specialization, high-tier rare equipment at item level 78 or higher can drop as an Exceptional base with over 20% quality or an additional augment socket.

Classes without item level

Some item classes do not use item level, including currency, Runes and Soul Cores.
