Damage Absorption
Explanation of how damage absorption/mitigation functions
How The Fortify Cap Works
Each of your individual resistances are capped at 50%. Seen here in your inventory:
However, if you’re able to achieve over 50% in this interface, via gems and protection perk, then your cap is set to the % displayed.
This means that if you have, for example, 52% Ice Resistance and you apply 30% Fortify:
Your Ice Resistance is set to 52%
You cannot increase your Ice Resistance above 52%, except via more gems, so the 30% Fortify is wasted.
30% Fortify is applied to all other resistances, and is capped at 50% in each resistance.
Damage Absorption Formula
Credit to
– This the best guess at the logic behind damage absorption in-game and is what the below calculator is based on.
AF = Affixes (Gems)
SE = Status Effects (Fortify via healer, abilities, oakflesh or gemstone dust)
ABSVitals = Ward armour perks and potions
MIN(MAX(AF+SE,MIN(AF,-0.3)),MAX(AF,0.5))+ABSVitals
Put simply, your absorption is: (AF + SE) + ABSVitals
- AF + SE is capped at 50%, unless AF is over 50% as mentioned above.
