Resistance

Resistance is a form of damage reduction that reduces damage of a particular type by a percentage. Players and enemies all have a resistance stat to each of Fire, Cold, Lightning and Chaos damage, and these are raised or lowered independently. Increases to "Elemental Resistance" are applied to fire, cold and lightning but not chaos.

Resistance has a default value of 0, where it does not affect the damage taken. Maximum resistances are soft capped at 75% by default but can be increased to a hard cap of 90%. Resistance can go into the negatives, which increases damage taken.

Characters receive a -10% penalty to elemental resistance at certain area level thresholds, approximately around the end of each act. By endgame, the cumulative penalty is -60% to all elemental resistances.

Honour Resistance is a stat used exclusively in Trial of the Sekhemas, and is calculated the same way.

Mechanics

Calculation

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}FinalDamage=D*(100-R)/100$

Example: being hit by 1000 fire damage, with a fire resistance of 30%, means you would take:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}1000*(100-30)/100=1000*0.7=700$ damage.

The higher your resistance gets, the more effective an increase in resistance is in reducing damage taken. This makes increases to maximum resistance a particularly valuable stat. For example, increasing resistance by 10 from 0% to 10% will reduce damage taken from 100% to 90%, or 10% less. But increasing by 10 from 60% to 70% would be reducing damage taken from 40% to 30%, reducing damage taken by a quarter.

Elemental Exposure

Exposure is a debuff applied to the player or an enemy that reduces their resistance to one of the three elements (fire, cold, or lightning) (by default -20% for 4 seconds), which can result in negative resistance values.

Curses

There are a variety of Curses that can reduce the resistance a character or enemy has to a specific type of damage:

Flammability for fire
Hypothermia for cold
Conductivity for lightning
Despair for chaos

Curses count as debuffs and stack with exposure. Note that debuffs from both exposure and curses affect uncapped resistance, regardless of maximum resistance.

Example: A player with 150% uncapped fire resistance and a maximum resistance of 75% would have their effective resistance unchanged after being hit with with -40% from the flammability curse, since the remaining 110% is still enough to reach maximum resistance.

Resistance Penetration

Having Penetration in a damage type reduces the effective resistance of enemies you damage with that type, thus increasing the damage they take. It stacks with exposure and curse debuffs, but is applied last and is only effective against positive resistances; it has no effect once the effective resistance 0 or negative. In exchange, it affects both maximum resistance and uncapped resistance.

Ignore resistance

Effects which cause damage to ignore enemy resistances will calculate damage as if the enemy had 0% of the ignored resistance, and ignores any further modifications to resistances. It does not affect the actual resistance, and does not interact with stats that care about the specific resistance value.
