Deadly Sequence is a Weapon Augment Mod that increases critical chance and Sequence specifically for the 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.


Rank Critical chance Sequence Cost
0 +50% 0.25 4
1 +100% 0.5 5
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 ReputationBlackx6425,000 to purchase.


  • The Grinlok has a base critical chance of 15%, so a maxed Deadly Sequence would result in a critical chance of 45%. Combining with a maxed Point Strike would bring the critical chance up to 67.5%.
    • Further adding Critical Delay results in a 74.7% critical chance, though at the cost of fire rate.
    • Adding an Argon Scope to the first combination would bring the critical chance up to 87.75% while aiming with the buff active. Or 94.95%, while aiming, with Critical Delay.
