History of Riskrunner

Riskrunner is an Exotic Submachine Gun that deals Arc damage. It is a 900 rounds-per-minute weapon with low impact and good stability.

Overview

Its intrinsic perk, Arc Conductor, makes the weapon more powerful and gives it Arc damage resistance while you are taking Arc damage, for example from Fallen enemies or Arc grenades. Kills extend the overcharged state. While Arc Conductor is active, its Superconductor trait lets shots become chain lightning that returns ammo to the magazine, which makes it strong at clearing groups.

Acquisition

• The A Spark of Hope questline (seven parts, starting with Commander Zavala in the Tower, with steps involving Ikora Rey, Devrim Kay and Lost Sectors in the European Dead Zone) ends with the "Risk/Reward" mission in the Cosmodrome and rewards Riskrunner.
• Exotic engrams and extremely rare world drops.
• Older routes included a choice reward (with Graviton Lance and Sunshot) after the story mission "Sacrilege", and the New Light quest "Pain and Gain".

Catalyst

The Riskrunner catalyst adds +27 range and a stronger Superconductor effect. Reported unlock requirements differ: 600 kills (300 regular, 300 chain lightning), or 500 kills and 50 chain lightning kills.
