Iron Helmet
What each level gives you
- Lv 3Critical Damage Resistance +X%.
- Lv 5Critical Damage Resistance +X%. Reduces the Impact of Critical Hits received.
Each row is everything Iron Helmet grants once the affix reaches that level, not what that level adds on its own. A roll below level 3 does nothing at all, and the second effect only appears at level 5. The magnitudes read X because they are not fixed: each one scales with the affix level on the individual roll, so two copies of the same piece can carry very different numbers.

How affixes work
Full guide →Affixes are the rolled modifiers that sit on weapons and armor. Each piece draws its affixes from an affix library, and an affix's effect scales with its level — so the same affix can be weak on a low roll and build-defining on a high one. Reroll and upgrade affixes with affix gems to push the breakpoints higher. In your inventory Iron Helmet sits in the blue group — survivability rolls that raise what you can walk into.
