The Stinging Truth mod is a Weapon Augment Mod that increases magazine capacity and Truth specifically for the Viper. It increases magazine capacity by 10 and Truth by 0.25 per rank, at a maximum of 40 and 1 at rank 3, respectively.
While the Viper is the active weapon, Truth causes affinity gained by Viper to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial attack dealing 1,000 Gas damage to enemies around the player, restores 25% of maximum Health, and temporarily boosts all 3 Parkour Maneuvers (Wall Latch and Aim Glide durations, as well as Bullet Jump velocity) by 25%.
- This mod is acquired by attaining the rank of Crusader with the Arbiters of Hexis, and spending 25,000 to purchase.
- The mod increases ammo capacity by a flat amount, rather than a percentage. Thus Stinging Truth adds 40 rounds to the Viper, giving it a total magazine size of 54 rounds.
- This mod is exclusive to the Viper, and cannot be equipped on the Twin Vipers and Wraith Twin Vipers.
