PoE2 Spirit Reservation Explained
Understand Spirit reservation math, overreservation, and how aura or meta gem costs affect your Path of Exile 2 build.
Quick Answer
Total Spirit is your budget, reserved Spirit is the active cost, and remaining Spirit tells you whether the setup fits.
Search intent
Understand the math behind reserved Spirit and overreserved setups.
Path of Exile 2 mechanics can change after balance patches. Treat this page as a planning aid and recheck important values in game after major updates.
Total Spirit comes first
Before evaluating reservations, calculate your total Spirit. The planner combines campaign Spirit, flat gear Spirit, and increased Spirit modifiers into a single total.
That total is the budget your persistent effects must fit inside.
Reserved Spirit is the active cost
Every enabled aura, buff, minion package, or meta gem contributes to reserved Spirit. The more effects you enable, the less unreserved Spirit remains.
A setup can look fine with one or two effects active, then fail once a trigger gem or another minion reservation is added.
Remaining Spirit tells you if the setup works
Remaining Spirit equals total Spirit minus reserved Spirit. A positive number means the planned setup fits. A negative number means the build is overreserved.
The planner highlights overreservation because it is one of the easiest build mistakes to make when theorycrafting from a list of desired skills.
Support and patch changes matter
Reservation values can be affected by gem choices, balance changes, and game updates. Treat every guide value as a planning aid, not a permanent rule.
After a patch, rebuild the setup in the calculator and confirm the final values in game.
FAQ
Why does my planned setup show overreserved?
Your active reservations cost more Spirit than your current total. Add Spirit, reduce reservation, or disable one of the planned effects.
Does the calculator replace checking in game?
No. It is a planning tool. Final values should be checked in game, especially after patches or gear changes.
