Exposure

Fire a bouncing Grenade that bursts in a spray of Oil when the fuse expires or when it impacts an Enemy, dealing minimal damage but covering the ground and nearby enemies in Oil. Oil created this way can be Ignited by Detonator Skills or Ignited Ground.

Curse all targets in an area after a short delay, lowering their Elemental Resistances.

Penetration causes the target's corresponding Resistance to be treated as lower than its actual value by the specified amount when of calculating Damage taken from your Hits. Resistances can only be Penetrated down to a minimum of 0% by default.

Resistances reduce damage of their matching type. Fire, Cold and Lightning Resistances are Elemental Resistances. Chaos Resistance is separate and does not benefit from modifiers that only say Elemental Resistances.

Maximum Resistance is the cap applied to a character's Fire, Cold, Lightning, or Chaos Resistance. The default maximum is 75% and the hard cap is 90%. Raising the maximum creates room for more effective Resistance but does not add the ordinary Resistance needed to fill that room.

Elemental Damage is the collective name for Fire, Cold, and Lightning Damage. A modifier to Elemental Damage can scale all three types, but each part is still mitigated by its matching Resistance and keeps its own ailment rules.

A Hit is an instantaneous damage event. Any damage that is not damage over time is Hit damage, whether it comes from an Attack, a Spell, Thorns, or another effect.

Damage is classified on three independent axes: source, delivery, and type. A component can come from an Attack, Spell, Thorns, or another source; deal a Hit or damage over time; and deal Physical, Fire, Cold, Lightning, or Chaos damage.

Debuffs are negative effects that deal damage or penalise stats for a duration or while a condition is met.

Duration is the length of time a skill component, Buff, Debuff, Ailment, Curse, Mark, Minion, Totem, Flask effect, Charm effect, Hazard, or delayed event remains active. Each duration modifier applies only to the effect type it names.

Ignite is a damaging Elemental Ailment that deals Fire damage over time for four seconds by default. A Hit's chance to Ignite comes from the target's total Flammability, including Flammability applied by that same Hit.

Detonator is a Skill tag for Skills that can trigger flammable gas, Oil, Grenades, lodged explosives, and similar effects when the Skill reaches them. The target effect defines what is consumed or activated and what the resulting explosion, Ignite, volley, or secondary effect does.
