The Entropy Spike mod is a Weapon Augment Mod that adds an explosion chance and Entropy specifically for the Bolto. It increases the explosion chance by 0.05 and Entropy by 0.25 per rank, at a maximum of 0.2 and 1 at rank 3, respectively. Explosions deal 250 Blast b Blast damage to the target, as well as to nearby enemies within 10 meters of the blast (scaled by distance).

While the Bolto is the active weapon, Entropy causes affinity gained by Bolto to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial explosion dealing 1,000 Magnetic b Magnetic damage to enemies around the player, restores 25% of base Energy, and temporarily increases the maximum Energy by 25% of the Warframe's base Energy amount.
