The Entropy Burst mod is a Weapon Augment Mod that increases status chance and Entropy specifically for the Supra. It increases status chance additively by +5 and Entropy by +0.25 per rank, at a maximum of +20 and 1 at rank 3, respectively.
While the Supra is the active weapon, Entropy causes affinity gained by Supra 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 base 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 to purchase.
- Unlike other rifle mods that affect Status Chance, Entropy Burst is an additive effect rather than a multiplicative one. This gives the Supra, with its base status chance of 30%, a 50% Status Chance (30% + 20%), rather than 36% (30% × (1 + 20%)).
- Entropy Burst will not affect the values of other status-effect mods like Rifle Aptitude, as its bonus to the base status chance is added after all other multipliers.
- When this augment was released the Supra had a base status chance of 5%, which this mod increased to 25%.
