Operation: Blood of Perita 
Our latest Operation: Blood of Perita begins today (December 16) at 11:30am ET! To participate in this Operation, you must have completed The Old Peace quest. 

For more information on how to participate, check out our official Operation Forum Post.

Changes:

• Updated various descriptions to better explain Tauron Strikes and their mechanics:
  • Updated Tauron Strike Focus node descriptions to add duration and enhance overall clarity.
  • Added clarification on how Tauron Strike charge is gained in the on-hover tooltip in the Tektolyst Artifact Upgrade screen.
    • 
    • As a reminder, Tauron Strike Charge can be gained by killing enemies, with or without Focus Lenses equipped (Lenses boost charge amount), and by picking up Convergence Orbs (which give you a base amount of charge on pickup and buff the charge rate from killing enemies for 45s). 
  • Players with a Tektolyst Artifact for their active Focus School will now see a pop-up in the Arsenal if a Lens is not installed on any item in their Loadout.
    • 
    • This pop-up explains that installed Lenses will charge their Tauron Strikes significantly faster!
  • Renamed “Persistent Effect” to “Temporary Effect” to indicate they have a limited duration.
  • Related Fixes:
    • Fixed the Spectral Pages Focus node giving +0% increased value per rank instead of the intended +10%. Also clarified that they grant base +10% Cast Speed, Strength, and Duration.
    • Fixed Overwhelming Power Focus node missing the "Warframe/Operator" category in the on-hover description.
• Made various tweaks to Vinquibus' SFX.
• Adjusted various cosmetic descriptions to remove specific mention of Warframes or Operators if those items can also be equipped by the Drifter. 

Top Fixes:

• Fixed various cases of players being in a broken state after the transition to the Archwing Stage of the Hunhullus fight.
  • We are still investigating edge-cases, but this fix should address the most common causes of this bug.
• Fix an issue where the Drifter shown in kiss cinematics might not match your actual Drifter.
• Fixed Lyon Allard's "Sacred Annihilation" Blessing applying to Melee weapons and Damage Over Time effects.
  • Also fixed it being able to insta-kill Invulnerable targets and Bosses.

• Fixed Yareli being unable to complete various Orders in The Perita Rebellion while on Merulina.

• Fixed Oraxia's fight Honoria not being awarded to Clients.
• Fixed a bug where Primary Overcharge would calculate infinite multishot.
• Fixed the Entrati Syndicate having an unintentional Mastery Rank 9 requirement as a result of the Keratinos Blueprint sacrifice.
  • We've swapped the required sacrifice to ONE Keratinos Blade Blueprint, so players still have less to farm than originally!
• Fixed cases of Clients being teleported to a previous hacking terminal if they encounter multiple hacking objectives in The Perita Rebellion.
• Fixed players not being teleported into Roathe's boss arena if they were outside of it when the fight is triggered.

• Fixed Arcane Irradiate triggering recursively off of Cyte-09's Resupply elemental ammo.
• Fixed Zid-An Uskos' heat buff not applying to Exalted Secondary Weapons.

  • Also fixed one of Roathe's abilities not instantly killing players when hit.
• Fixed entering a new Infernum and then dying as Operator/Drifter in Descendia causing players to spawn in the previous Infernum where their Warframe was last used.
• Fixed breaking all the tumors too quickly causing the Hive mission to become progression stopped in Descendia.
• Fixed kills that occur outside of the objective tile causing Authorization Codes to spawn far away in the Makvoss Cannon objective in The Perita Rebellion.
• Fixed an issue where the Auroch Supply Vehicle would have an incorrect amount of health in the rare case the objective is rolled more than once during The Perita Rebellion.
  • Also adjusted the Auroch Supply Vehicle's speed to be more consistent across levels.
• Fixed Orokin dropships not having collision in The Perita Rebellion.
• Fixed only one player in a squad being able to receive the Exorcist Honoria in Descendia.
