History of Arc Conductor

Arc Conductor is the intrinsic of Riskrunner, an Exotic Submachine Gun. When the wielder takes Arc damage, the weapon becomes more powerful and resists incoming Arc damage. Kills extend the overcharged state, which lasts about 5 seconds and boosts damage while active. Arc damage the player deals to themselves, such as a grenade at their feet, can also trigger it.

Riskrunner's Superconductor trait works with it to chain lightning. The trait also appears on Ergo Sum, a random-roll Exotic Sword, which is one way to get it on a melee weapon. Reported Arc resistance varies by source; one 2024 build guide gives 50%.
