Spirit is an all new resource to keep track of in Path of Exile 2. Unlike Health and Mana, Spirit is not consumed and recovered at will, but is instead held in a pool, to be reserved and used by buffs, auras, and summons.
Beginning with none, you will gain Spirit as you progress through the game. Later on, an ever increasing pool of Spirit will be required for new abilities or more minions, but sources will be far and few to come by. Correspondingly, Spirit costs for some abilities can be decreased through certain skill nodes. This guide has every currently known method to increase Spirit in Path of Exile 2.
Gear
Initially, the only way to have a Spirit reserve is through an item. Sceptres are the only known weapon to offer Spirit, supplying a generous base of 100. This can increase with any modifiers that may be present, usually expressed as ‘X(#-#)% Increased Spirit’. Sadly, Sceptres cannot be dual-wielded.
Body Armour, Focuses, Shields, and Amulets can all roll with a straight bonus to Spirit, expressed as ‘+X(#-#) To Spirit’.
This method can be severely limiting on progression, as you are now tied to a set of gear that may not be up to the task for the content you are playing.
Bosses
A handful of bosses can specifically award you with Spirit, +30 each to be exact. On the map, their legend is notably distinct from regular bosses, and is denoted by a skull overlaid with a plus in the lower-left corner. This indicates that they are a ‘Boss Encounter With Upgrade’. The names and locations of known bosses specifically with Spirit upgrades are:
King in the Mist
Act 1
Freythorn
Ignaduk, the Bog Witch
Act 3
The Azak Bog
After you have felled a boss, be sure to collect and consume the Gem-prefix Skull drop, in order to actually apply each of these Spirit boosts permanently.
You may then double up on these Spirit rewards on a Cruel difficulty run, for a total of 120+ Spirit.
If the pattern is maintained, there ought to be an optional boss somewhere in Act 5 that grants a Spirit buff reward, but that remains to be seen until Path of Exile 2 exits Early Access.
Skill Nodes
Exclusive to the Witch class and her Infernalist Ascendancy, is the skill ‘Beidat’s Will’. This skill reserves 25% of Life, in exchange for +1 to Maximum Spirit per 25 Maximum Life. While potentially a troublesome trade-off, there are far more ways to extend and retain Life/Health than there are to increase your Spirit reserve.
An indirect way to increase the Spirit pool is to actually lower the Spirit reservation of the abilities themselves. Two such passive nodes are ‘Lord of Horrors’ which sees “Minions have 12% reduced Reservation”, and ‘Fate Finding’ which gives a “15% reduced Reservation of Herald Skills”.
Eventually there may well be more nodes hidden somewhere in the skill constellation which will either increase Spirit or reduce its reservation for a given ability, perhaps once Path of Exile 2 finally leaves Early Access.
That is every possible way to raise Spirit at this time in Path of Exile 2.
