Deadly Sequence is a Weapon Augment Mod that increases critical chance and Sequence specifically for the DEGrinlok Grinlok and PrismaGrinlok Prisma Grinlok. It increases critical chance by 50% and Sequence by 0.25 per rank, at a maximum of 200% and 1 at rank 3, respectively.

While the Grinlok is the active weapon, Sequence causes affinity gained by Grinlok to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial attack dealing 1,000 Radiation b 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.

2 +150% 0.75 6
3 +200% 1 7


  • This mod is acquired by attaining the rank of Senior Executive with The Perrin Sequence, and spending ReputationLargeBlack25,000 to purchase.


  • Deadly Sequence is additive with similar mods. For example, a DEGrinlok Grinlok with a max rank Deadly Sequence and Point Strike will have a 15% × (1 + 200% + 150%) = 67.5% critical chance.
