Persistent Skills are toggled in the Skills Panel instead of being used normally and often need to Reserve Spirit in order to be activated.

Buffs are effects that boost a player or monster's stats for a duration or while a condition is met. Unless otherwise stated, Buffs of the same type do not stack — only the copy with the strongest effect applies.

Any damage that isn't damage over time is Hit damage. Damaging Ailments which result from a Hit will calculate their damage from that Hit, and will not subsequently have Damage modifiers applied directly to them. As a result of this, raising Hit Damage will result in more powerful Damaging Ailments innately.

Resistances reduce damage taken of the corresponding damage type — Fire, Cold, Lightning or Chaos — up to a Maximum. Fire, Cold and Lightning Resistances are Elemental Resistances. Resistances can be improved with Equipment, Passives & Quest items. Your Elemental Resistances are lowered as you progress through the game. Elemental Resistances are a vital defensive tool, and should be one of the first things to check if you're having difficulty surviving.
