Resistance

Resistances affect the amount of damage taken of specific damage types when all avoidance forms have failed. Enemies can also have resistances, which are indicated beneath their life bar.

Each damage type except physical has its own resistance value which is viewable on the Defence tab in the Character panel (default hotkey C). Physical damage is mitigated by armour.

Chaos damage is not elemental, thus "+% to all Elemental Resistances" does not affect chaos, but "+% to all maximum Resistances" does. Chaos resistance can be modified by items and passive skills. The Keystone passive skill Chaos Inoculation grants total immunity to Chaos damage.

Mechanics

Damage mitigation

Resistances mitigates the incoming damage according to

<math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} \begin{align} \text{dmg}_{\text{red} } & = (1 - \text{Resistance}) * \text{dmg} \end{align}

   </math>

where dmg_red is the damage after reduction, Res is the character's resistance and dmg is the initial damage.

The damage ratio between a character with -60% resistance and a character with 75% resistance that are hit with same amount of damage is

<math display="" style="background-color:transparent; padding:0;"> \color[RGB]{163,141,109} \begin{align} {{1 - (-0.6)}\over{1 - 0.75}} & = 6.4 \end{align}

   </math>

Resistance penetration

Main article: Penetration

Penetration is applied as damage is dealt, after other resistance calculations. This means that Penetration will affect damage dealt even if the target's raw resistance value is far above its resistance cap.

Both reduction (as from curses), and penetration (as from Penetration gems), can reduce a target's resistance below 0%. There is no minimum resistance floor.

Resistance penalties

A penalty to all resistances is applied to player characters depending on their progression in the story.

• Completion of Act 5: -30% to all resistances
• Completion of Act 10: -30% to all resistances (-60% total)

Uncapped resistances

Uncapped resistances are shown in parentheses

Total resistances a character has are uncapped resistances. This total is affected by the difficulty penalties. Only resistances up to a player's maximum will provide damage mitigation, but a player may have their uncapped resistances lowered by curses, potentially reducing them below their maximum.

Unique items affected by uncapped resistances

Maximum resistances

Each resistance has the following cap: {{#ask:

-Has subobject::Character
Has stat id::~*resistance*
Has stat id::~*max*
|?Has stat text=
|format=ul
|sort=Has stat text
|mainlabel=- 

}}

There are various ways to alter the maximum resistances:

• Auras: Purity of Fire, Purity of Ice, Purity of Lightning
• Flasks: , ,
• Passive skills: Barbarism, Chaos Inoculation, Survivalist, Unnatural Calm
• The "of Exposure" affix on maps
• Corrupted armour and amulet with mod +1% to all maximum Elemental Resistances
• Uniques:
