"Fire is the breaking of bonds. Fire is freedom. We must be swift and thorough in our liberation..." The Purifier Robes' Exotic Perk is called [b]Burn Brighter, which causes all enemies killed by Ignite effects to explode[/b] similarly to Bloom and Combustion. Ignite effects being the Burn Damage from Scorch, and the Burn Damage caused by Grenades with Touch of Flame equipped. Other perks are Fusion Rifle Ammo and Heavy Weapon Ammo, which increase the amount of Fusion Rifle ammunition and Heavy ammunition you can carry respectively. There are also the normal Upgrade Defense nodes which increase the ARMOR value of the Chestpiece. EDIT: This is an old post, just going to point that out since it was recently bumped. All the information you're reading off of this is the [b]OLD[/b] Purifier Robes that was datamined.
