Item Levels & Requirements

Item level controls innate base scaling, affix-tier access, class gates, implicit scaling, and equipment requirements. It is separate from rarity.

Map bands

Each map tier normally drops a ten-level item band:

$$\begin{array}{ccl} \text{Tier }1 &\longrightarrow& \text{iLvl }1\text{--}10 \\ \text{Tier }2 &\longrightarrow& \text{iLvl }11\text{--}20 \\ \vdots && \vdots \\ \text{Tier }15 &\longrightarrow& \text{iLvl }141\text{--}150 \end{array}$$

Gear has a 15% chance to roll from one band higher than the current map, capped at the maximum item level.

Base-stat scaling

Weapon damage, armour, evasion, and energy shield use:

$$M_{\text{tier}} = 1.4^{\max(1, L_{\text{item}} / 10) - 1}$$

The multiplier is applied to the base’s own physical, elemental, or defensive multipliers. Rarity never enters this calculation.

Affix-tier unlocks

Gear-affix tiers unlock at these item levels:

$$\begin{array}{c|rrrrrrrrrr} \text{Affix tier} & T1 & T2 & T3 & T4 & T5 & T6 & T7 & T8 & T9 & T10 \\ \hline \text{Minimum iLvl} & 1 & 15 & 30 & 45 & 60 & 75 & 90 & 110 & 130 & 150 \end{array}$$

Signature families require iLvl 71. Mythic families require iLvl 141.

See the complete Gear Affix Compendium for family-specific ranges and eligible bases.

Level requirement

$$L_{\text{required}} = \begin{cases} \max\left(1, \left\lfloor L_{\text{item}} / 2 \right\rfloor\right), & 1 \le L_{\text{item}} \le 100 \\ 51, & 101 \le L_{\text{item}} \le 139 \\ 52, & 140 \le L_{\text{item}} \le 149 \\ 53, & L_{\text{item}} = 150 \end{cases}$$

Attribute requirements use each base’s Strength, Dexterity, and Intelligence profile. Attribute-requirement reduction can lower those three values by up to 50%, but the level requirement remains fixed.

Base catalog

Every base page shows example damage, defenses, implicits, and requirements at item levels 1, 50, 100, and 150. Start with the Item Base Index.
