The Toxic Sequence mod is a Weapon Augment Mod that increases status duration and Sequence specifically for the Acrid. It increases status duration by 50% and Sequence by 0.25 per rank, at a maximum of 200% and 1 at rank 3, respectively.
While the Acrid is the active weapon, Sequence causes affinity gained by the Acrid 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.
- Status Effects have a base duration of 6 seconds (needs confirmation; Acrid may have longer innate duration). With Toxic Sequence, the Acrid can extend the duration of Status Effects to 18 seconds. If combined with Perpetual Agony, the Acrid's status effects can be extended up to 20 seconds.
