POE2 Mercenary： Lightning AOE Build - Endgame Insane Damage Guide!

He adds a fourth support gem, raising Galvanic Shards to 1,033 DPS and prioritizing raw damage over shocks. He removes crossbow and critical investments, retaining projectile, attack, lightning, and elemental bonuses for a broadly distributed pure-DPS tree. Enemies are shredded without crits; Close Combat restores shock and proximity damage, while slow reloads remain the main weakness.

The build shifts from crit dependence toward reliable base damage, but reload limitations remain.
