History of Breakthrough (perk)

Overview

Breakthrough is the trait on Bastion, an Exotic Fusion Rifle. It makes the weapon fire staggering projectiles, which are strong against Unstoppable Champions. A stagger stops a champion that would otherwise keep rushing you, so it is the answer to that champion type.

The intrinsic perk on Bastion is Saint's Fists, which fires three spreads of Kinetic slugs.
