FAQ

Path of Exile 2 — Frequently Asked Questions

Answers to the most common questions about Path of Exile 2 calculators and strategies.

Q.How does the Atlas Passive Tree work in PoE2?

The PoE2 Atlas tree provides up to 132 permanent passive points (120 from leveling + 12 from Precursor Fortresses). Because Atlas points cannot be refunded individually without a full reset, optimizing mechanic prioritization (Expedition, Delirium, Ritual) and sustaining Waystones via Alchemy Orbs is crucial.

Q.How does Spirit replace Mana reservation in PoE2?

Spirit is a dedicated secondary resource pool (100 Base Spirit). Permanent buffs like Determination, Grace, Heralds, and persistent Skeletal Minions reserve flat Spirit instead of a percentage of your Mana pool, leaving your entire Mana globe free for casting.

Q.What is the physical mitigation formula for Armour in PoE2?

The physical mitigation formula is Armour / (Armour + 5 * RawHitDamage), capped at 90%.

Q.What is the difference between Increased and More damage in PoE2?

Increased modifiers are additive across all passive and gear sources before being applied (Base * (1 + Sum(Increased%))). More modifiers are multiplicative individual multipliers that compound exponentially.
