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 5%, a 25% Status Chance (5% + 20%), rather than 6% (5% × (1 + 20%)).
- Entropy Burst indirectly increases the overall effectiveness of rifle mods that increase status chance such as rifle aptitude by increasing the base status chance of the weapon. This mod makes it more worthwhile to mod for status on the Supra.
