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.
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 damage to enemies around the player, restores 25% of maximum Energy, and temporarily increases the maximum Energy by 25% of the Warframe's base Energy amount.
- This mod is acquired by attaining the rank of Wise with Cephalon Suda, and spending 25,000 Standing to purchase.
- This mod can only be used with the Bolto, and not with the Akbolto or Telos Akbolto.
- The explosion has a radius of 10 meters.
