Missing Note from The Old Peace:

• Added six Lunar New Year Decorations to the Dojo!

The Perita Rebellion Boss Changes and Fixes:

• Fixed The Perita Rebellion bosses not scaling properly with Steel Path modifiers.
  • These enemies died really quickly despite being the “finale” of the mission. We have fixed Steel Path modifiers not applying to them, and tweaked their Steel Path health values to ensure their difficulty matches what is expected at this level of content. 
  • With the tweaks to the Hunhullus, Archguns have been buffed in the Archwing Stage to keep the time-to-kill consistent with what it was before this change.
• Prime Vanguard Fixes:
  • Fixed Commandeered Primes Codex entry listing resistances to all damage types (instead of only the ones they are actually resistant to).
  • Fixed an issue with Commandeered Ember Prime's Fireball casting speed in The Perita Rebellion.
  • Fixed Commandeered Volt Prime's shield blocking his own projectiles in The Perita Rebellion.
• Hunhullus Changes and Fixes:
  • Added indicators to the Orbs that can be shot to negate the Hunhullus’ death laser ability in the Archwing stage.
  • Fixed the Hunhullus not being immune to armor stripping.
  • Fixed pre-set builds for loaner Archguns in the Hunhullus fight not properly applying, causing their damage output to be very underwhelming.
    • Known Issue: this fix only applies for Hosts, Clients are still experiencing this issue.
  • Fixed Void buff from Marrowtick grapples not displaying immediately on ammo count for Clients.
    • Also fixed the Void buff timer not refreshing with new Grapples for Clients.
  • Fixed the Hunhullus not being immune to armor stripping.

Changes:

• General polish for Drifter Beard fit.
• Non-boss Commandeered Prime Warframes in The Perita Rebellion now drop 2 Tektolyst resources when killed on the Steel Path.
  • They have a chance of dropping Lyroic Bridge, Ren Hypercore, or Ascaris Prime, regardless of which Recall mission you are playing. 
  • Also fixed loot abilities applying to Commandeered Prime Warframes, to keep them consistent with Acolytes.
• Arcane Persistence’s effect is now negated by Nullifiers, Magnetic Status Effects, and other similar nullifying effects.
  • This Arcane's effect offers a powerful new playstyle for survivability, but with certain setups, players can become fully immortal with no need to engage with any of the challenges a mission presents. This wrinkle adds an extra consideration for those who might wish to AFK, but also preserves meaningful challenge against "hard mode" bosses and other late-game content.
• Added the Harrowing Spire Stance to The Old Peace Uriel Bundle and The Old Peace Complete Collection (Platinum and paid). 
  • As mentioned in our PSA, those who had purchased these bundles before this Hotfix will be receiving the Stance in a script tomorrow. We’ll update the PSA once the script has begun. Thank you, Tenno!
