Lasting Purity is a Weapon Augment Mod that adds Dead Aim (damage while zoomed in) and Purity specifically for the Vulkar and Vulkar Wraith. It increases Dead Aim by 15% and Purity by 0.25 per rank, at a maximum of 60% and 1 at rank 3, respectively.
While the Vulkar is the active weapon, Purity causes affinity gained by Vulkar to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial attack dealing 1,000 Corrosive damage to enemies around the player, restores 25% of maximum Health, and temporarily increases the maximum Health by 25% of the Warframe's base Health.
- This mod is acquired by attaining the rank of Pure with New Loka, and spending 25,000 to purchase.
- Dead Aim increases damage when zoomed in. This damage increase stacks multiplicatively with base damage mods and elemental mods.
- Lasting Purity features a syndicate radial proc that will induce screen shake when activated, this can hamper some users as it will disturb the weapon crosshair whilst scoped.
