In the expansive universe of Path of Exile 2, virtually every spell and ability relies on Mana for execution. While some character builds prioritize standard attacks, engaging combat often necessitates utilizing various skills to surpass the limitations of basic strikes.
For Mana-intensive spell-casting classes, this resource can deplete quickly, even for those possessing a high maximum Mana pool. The Arcane Surge mechanic is particularly beneficial for players who completely exhaust their Mana during confrontation. Let’s delve deeper into how this functionality operates.
How to Acquire Arcane Surge in Path of Exile 2

Arcane Surge is classified as a support skill that you can access by utilizing a Support Gem. This gem is located at the top of the intelligence skills roster. Once embedded, it can be used alongside any skill you have unlocked. It is important to note that support gems typically enhance only the skill they are directly applied to. However, all skills affected by Arcane Surge will be displayed when you hover over the equipped support gem in the menu.
Understanding Arcane Surge in Path of Exile 2


To activate Arcane Surge, you must utilize 100% of your Mana on a chosen skill that has the support gem equipped. The natural recovery of Mana means that activation does not require total depletion—rather, it triggers as soon as you expend your entire Mana capacity on that skill. For instance, if your maximum Mana is 100, you’ll need to utilize 100 Mana on the specific skill, disregarding the amount reflected by the Mana orb at the bottom of your screen. Upon activation, Arcane Surge provides the following enhancements:
- 10% increase in cast speed for all spells.
- 20% improvement in Mana recovery rate.
- Duration: 8 seconds.
When Arcane Surge is triggered, a small blue orb will manifest around your character and orbit them for the duration of eight seconds. Additionally, a timer and the Arcane Surge icon will be visible in the top left of your hotbar, allowing you to monitor its effectiveness clearly. The augmentation of casting speed grants a substantial advantage, making Arcane Surge an indispensable asset for any spell-centric characters such as the Witch or Sorceress. The enhancement in Mana recovery dovetails perfectly with the increased casting speed, ensuring that you can swiftly utilize your spells even as your Mana depletes rapidly.
