Tradeable Cannot be obtained from transmutation Covenant Augment: Headshot kills increase Critical Chance bonus duration by 3s. Zenurik  8,000 Update 22.10 (2018-01-25) https://www.warframe.com/droptables Lasting Covenant is a Warframe Augment Mod for  Harrow that increases  Covenant's critical chance buff duration each time an enemy is killed with a headshot. Stats[] Rank Duration Increase Cost 0 1s 6 1 1.5s 7 2 2s 8 3 3s 9 Acquisition[] This mod can be acquired by attaining the rank of Maxim under the Arbiters of Hexis, or the rank of Exalted under the Red Veil, and spending 25,000 Standing to purchase. This mod can periodically be acquired from The Circuit. Notes[] Bonus duration awarded from headshots is affected by Ability Duration. The limit of bonus duration is three times of duration of critical chance buff. For Ability Duration of 130%,  Covenant would have 15.6s of critical chance buff initially, and bonus time would cap at 46.8s. This can be continually replenished up to the cap with more headshot kills, allowing for unlimited duration as long as the user continues to gain headshot kills frequently enough. Tips[] Synergizes well with Harrow's first ability,  Condemn, as it puts enemies in a position that allows for easier headshots. Maximization[] Input table not loaded.
