The Sequence Burn mod is a Weapon Augment Mod that increases weapon range and Sequence specifically for the Spectra. It increases the range additively by 5 and Sequence by 0.25 per rank, at a maximum of 20 and 1 at rank 3, respectively.
While the Spectra is the active weapon, Sequence causes affinity gained by Spectra to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial attack dealing 1,000 Radiation damage to enemies around the player, restores 25% of maximum Shields, and temporarily increases the maximum Shields by 50% of the Warframe's base Shields.
- This mod is acquired by attaining the rank of Senior Executive with The Perrin Sequence, and spending 25,000 to purchase.
- With this mod equipped, the Spectra can achieve a beam length of 35 meters, more than doubling the weapon's range. Combining this with Ruinous Extension results in a 43-meter beam length, nearly triple the original range.
