Path of Exile 2 Cast on Critical Mechanics FAQs
How is Energy gain calculated on critical hits?
Energy gain is based on the Power of the enemy and the percentage of their Ailment Threshold affected by your critical hit. Stronger enemies yield more Energy per hit.
Can Cast on Critical trigger multiple spells at once?
Yes. When maximum Energy is reached, all socketed spells are triggered simultaneously. This allows for burst combos if cast-time and Energy scaling are optimized.
Does Cast on Critical snapshot stats or update dynamically?
It snapshots your stats at the moment of spell triggering. Buffs or debuffs applied after Energy reaches maximum will not affect the triggered spells.
Can Cast on Critical be used with cooldown-based spells?
Yes, but cooldowns must be managed carefully. Spells on cooldown will not trigger, so layering spells with different cooldowns or durations is recommended.
Does Energy scale with cast-time of socketed spells?
Yes. The gem has 10 maximum Energy per 0.1 seconds of base cast time of socketed spells. Longer cast-time spells allow higher Energy thresholds before triggering.
