History of Arc Weapon Surge

Arc Weapon Surge is a leg armor mod that boosts the damage of Arc weapons while the wearer has Armor Charge. Surge mods on leg armor took over the role of the older damage mods.

Armor Charge is gained mainly from Orbs of Power. While an Armor Charge mod is equipped, picking up an Orb of Power grants one stack, up to three by default. Other sources include Elemental Charge, which grants stacks from subclass pickups, and Stacks on Stacks, which boosts orb-based gains on leg armor.
