Their availability and prices are not affected by the player's reputation with The Perrin Sequence syndicate. Each of these weapons is offered with a random bonus element that cycles every four days. The weapons are eligible for Valence Fusion. The minimum number of Corrupted Holokeys needed to purchase each Tenet melee weapon once is 200 (40*5). The absolute maximum number of Corrupted Holokeys to purchase each Tenet Melee and fully upgrade each via Valence Fusion is 2000 (40*10*5). 40Tenet Grigori (MR 14) 40Tenet Livia (MR 14) 40Tenet Exec (MR 16) 40Tenet Agendus (MR 14) 40Tenet Ferrox (MR 16) Time until next Glast's Tenet melee shop reset: 61 hours 34 minutes 23 seconds  Patch History[] Update 30.7 (2021-09-08) In the final Railjack Showdown node for a Sister of Parvos, each Sister will give each squad member 1 Corrupted Holokey at End-of-Mission whether you Vanquish or Convert them! This means a Squad of 4 can leave with 4 Corrupted Holokeys each on Showdown mission complete! Corrupted Holokey drop amounts have been increased in Void Storms! Void Storms in the Veil Proxima will now drop 10 (vs 6) to make the hardest content the most rewarding. The rest have all had their amounts increased by 1.

Hotfix 30.5.4 (2021-07-17) Fixed functionality loss when clicking through Ergo Glast’s Tenet Offerings too quickly. Fixed inability to Chat Link Corrupted Holokeys.
