Spirit & Reservation

What Spirit is, what reserves it, and how reservation efficiency actually divides the cost

Spirit is the resource that keeps your permanent skills running — heralds, auras, persistent buffs and minions all reserve it, and nothing else can use what they hold.

Efficiency modifiers are divisors, not subtractions, which is why the same 50% reads as a 33% saving.

Working out your Spirit budget

107 skills reserve Spirit in Path of Exile 2, and 14 unique items grant it. The Spirit budget calculator adds up your permanent rewards, sceptre and gear, then subtracts everything you want running at once.

  • Support gem cost multipliers do not change a reservation — only reservation efficiency and flat reduction do.
  • Reservation efficiency divides the cost, so 100% increased efficiency halves it.
  • Each weapon set can reserve a different amount, because sceptres and weapon-set passives belong to a set.

Spirit

Spirit is a reserve of power used to activate and maintain skills with permanent effects. Spirit-powered skills are managed within the Skills Panel.

Weapon Sets can have differing amounts of available Spirit, due to weapons with Spirit (such as Sceptres), Weapon Set Passive Skills, or Persistent Skills that are active in specific Weapon Sets.

Reservation

Reservation effects prevent a portion of a given resource — usually Spirit, though it can also be Life or Mana — from being used for other purposes while active. Reserving a resource does not change the maximum value of that resource.

Efficiency

Efficiency modifiers act as divisors to the stat they modify. For example, 50% increased Reservation Efficiency causes your Reservations to be 67% of their base value, 100% increased Reservation Efficiency causes your Reservations to be 50% of their base value, and so on. Reduced Reservation Efficiency will cause the modified stat to grow larger instead of smaller.

Persistent Skills

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

Herald Skills

Herald Skills are a type of Persistent Buff that grant powerful effects on killing enemies.

Auras

Auras apply Buffs to Allies within a radius, or Debuffs to enemies within a radius of the source of the Aura.

Presence

Your Presence is an area around your character within which certain effects (such as many Auras) are applied. By default this has a 4 metre radius. The size of this area can be modified by Presence Area modifiers, but not by Skill Area modifiers.

Minions

Minions are summoned Allies which will accompany and fight alongside you. Persistent Minions will reserve a portion of Spirit while active.

Companions

Companions are a type of Reviving Minion that are more complex and powerful than typical Minions. By default you can only have one Companion of any type summoned at a time.

Meta Gems

Meta Gems are Skill Gems that other Skill Gems can be socketed into. They can use, Trigger, or otherwise apply the effects of those other Skill Gems. Skill Gems and Support Gems can be socketed into Meta Gems interchangeably, though most Meta Gems require at least one Skill Gem to be socketed to function.

Meta Gems can never be socketed into other Meta Gems.

Sceptres

Sceptres are One-Handed weapons that require Strength and Intelligence to equip. Sceptres can be equipped in your main hand or off hand, but you cannot Dual Wield two Sceptres.

Sceptres cannot be used to Attack and do not grant bonuses to Spellcasting. Instead, they grant additional Spirit and can provide bonuses to your Allies.

Buffs

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.

Debuffs

Debuffs are negative effects that deal damage or penalise an entity's stats, either for a set duration or when a condition is met.

Unless otherwise stated, Debuffs of the same type do not stack — only the copy with the strongest effect applies.

Buff/Debuff Magnitude

The Magnitudes of a Buff or Debuff are the values of the stats it applies to the target. A Buff or Debuff with higher magnitudes is more powerful.

Modifiers to the Magnitude of Buffs or Debuffs come from whoever applies it and are multiplicative with modifiers to the Effect the Buff or Debuff has on the target.

Buff/Debuff Effect

Modifiers to the Effect of Buffs or Debuffs usually come from the target it affects and are multiplicative with modifiers to the Magnitudes of the Buff or Debuff, which come from its creator.

Non-Stacking Effects

This effect does not stack. Applying it again before the first expires will refresh the duration.

Common questions

What is Spirit in Path of Exile 2?

Spirit is a reserve of power used to activate and maintain skills with permanent effects. Spirit-powered skills are managed within the Skills Panel.

How does reservation efficiency work?

Efficiency modifiers act as divisors to the stat they modify. For example, 50% increased Reservation Efficiency causes your Reservations to be 67% of their base value, 100% increased Reservation Efficiency causes your Reservations to be 50% of their base value, and so on.

Does reserving Spirit lower my maximum Spirit?

Reservation effects prevent a portion of a given resource — usually Spirit, though it can also be Life or Mana — from being used for other purposes while active. Reserving a resource does not change the maximum value of that resource.

Can my two weapon sets have different Spirit?

Your character has two Weapon Sets that can be used independently by equipping items into both sets. By default your Skills will use the currently active Weapon Set if possible, or automatically swap to your other Weapon Set if required to use the Skill. You can also specify the Weapon Set you want to automatically swap to for each Skill in that Skill's information panel. In addition to changing your active items, Weapon Sets also have dedicated Passive Skill Points that can be allocated differently in each Weapon Set.
