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.
- Stinging Truth will not affect the increases of Slip Magazine and other magazine size mods, as they still scale off of the Viper's relatively low magazine size, making Stinging Truth much more efficient.
- This mod is exclusive to the Viper, and cannot be equipped on the Twin Vipers and Wraith Twin Vipers.
- This allows the Viper to beat even the Wraith Twin Vipers in magazine size, while remaining much more accurate, though with a slower fire rate as well.
