Power, Frenzy, and Endurance Charges in Path of Exile 2

Charge generation in PoE2 comes from three broad buckets: active skills, support gems, and passives or items. A skill like Killing Palm grants a Power Charge whenever it scores a kill. The Combat Frenzy setup grants a Frenzy Charge each time you apply a Freeze, Electrocute, or Pin effect, gated by a short cooldown so you cannot trigger it every frame. Warrior tools such as Magma Barrier grant an Endurance Charge when you block during the buff.

Some passives and keystones add or convert generation. The Resonance keystone, for example, redirects which charge type you gain, letting a build that would generate one type instead gain another. Items with implicit or crafted modifiers, such as Frenzy Charge on Kill, provide generation that scales with how many enemies you defeat.

• Active skills: Killing Palm (Power), Magma Barrier (Endurance), Cull the Weak (Frenzy).
• Support gems: Combat Frenzy (Frenzy on Freeze, Electrocute, or Pin), Retort (Frenzy when consuming a Parried debuff), Break Endurance (Endurance chance on fully breaking armour).
• Marks: Sniper's Mark grants a Frenzy Charge when you critically hit a marked enemy.
• Passives and keystones: Grit, Cranial Impact, and Resonance alter maximum and conversion.
• Items: implicit or crafted modifiers such as Frenzy Charge on Kill.

Three numbers govern a charge system, and players often blur them. Maximum Charges is the cap you can hold at once. Charge Duration is how long a held charge persists before it expires. Generation amount is how many charges a single event grants. Raising one does not raise the others.

For example, a passive may raise your Maximum Endurance Charges while a separate modifier extends Duration, and a generation skill may grant only one charge per trigger regardless of your maximum. Treat them as independent dials when planning a build.

• Maximum Charges: the per-type cap; raised by passives, keystones, and some belt or ring enchants.
• Duration: how long a charge survives untended; extended by specific nodes and items.
• Generation amount: charges granted per event; often a fixed 1 per qualifying trigger.
• Do not assume a higher maximum means faster or automatic generation.

The payoff of charges is consumption. In PoE2 you spend charges through skills, supports, or passives that explicitly state they interact with a charge type. The consumed charge empowers the effect rather than passively buffing you.

Examples: Falling Thunder consumes Power Charges to add lightning projectiles and increase damage; Barrage consumes Frenzy Charges to add repetitions to the next bow attack; Infernal Cry consumes all Endurance Charges to empower subsequent attacks and make enemies combust on death. The Amazon's Infuse Weapon triggers elemental infusions when you consume Power, Endurance, or Frenzy Charges. The persistent Charge Infusion skill grants buffs based on your active charges and consumes charges on a timer.

• Power spenders: Falling Thunder, Charge Infusion (crit bonus on consume).
• Frenzy spenders: Barrage, Amazon Infuse Weapon (Lightning Infusion), Tumult.
• Endurance spenders: Infernal Cry, Seismic Cry, Shielding Cry, Rally, Amazon Infuse Weapon (Fire Infusion).
• A charge is worthless unless something in your build consumes it.

PoE2 has a real charge-conversion mechanic: the Resonance keystone. When allocated, it changes which charge type you gain from generation sources — you gain Power Charges instead of Frenzy, Frenzy instead of Endurance, and Endurance instead of Power. This lets a build funnel generation into the single charge type its consumers want.

Outside keystones, individual skills and supports define exactly which charge they grant or consume; there is no automatic universal conversion between charge types. If a skill says it grants or consumes a specific charge, it only ever interacts with that type.

• Resonance keystone: redirects generated charge type (Power, Frenzy, Endurance cycling).
• Skills and supports are type-specific: a Frenzy consumer never spends Power or Endurance.
• No global 'any charge' pool exists; the three types remain distinct resources.
