Changes:

• Updated the materials and tint order on Caliban Prime, Venato Prime, Vadarya Prime, and the Neurovyre Prime Syandana.
  • We very rarely make significant changes to appearances post-release, but felt that Caliban Prime’s materials and tint order meant he did not work optimally with other Caliban cosmetics. Mixing and matching pieces is an important part of Fashion Frame, so we changed Caliban Prime as follows:
    • Updated the metal plate material so that applied tints are more saturated.
    • Swapped the Primary and Secondary tint channels so that the metal plate details are on the same tint channel as those on Caliban and the Caliban Orfeo Skin.
    • Venato Prime, Vadarya Prime, and the Neurovyre Prime Syandana have received the same changes so they match Caliban Prime.
  • 
• Turned off the Dog Days music in Relays now that the event is soon ending.
  • We're thankful that Nakak collabed with Nora Night to get that tune blasted in the Relays, but we're aware it was causing some issues with other SFX in these areas. Something to consider if it returns next year!
• Players can now interact with tooltips for settings that are disabled.

Top Fixes:

• Fixed Vadarya Prime's chain lightning being able to trigger recursively off of Blast Status Effects, leading to substantial performance issues.
  • Blast Status Effects were unintentionally being considered as another hit from the Vadarya Prime, which would trigger more chain-lightning, which would trigger more Blast Status Effects, and so on and so on. If there were enough enemies to continue chaining this event, it led to significant game performance issues.
    • EDIT: For ultra clarity, the Vadarya Prime still has a chance to strike nearby targets with lightning rods. We have not removed the lightning feature, only its interaction with triggering recursively off Blast Status Effects.
• Fixes towards Vadarya Prime's chain lighting not jumping to enemies that are out of Line of Sight.
• Fixed cases of Void Relics being unavailable in the Relic selection screen after refinement.
• Fixed Garuda's Dread Mirror and Blood Altar having too restrictive Line of Sight checks, notably for vertical obstructions (like pillars).
• Fixed Yareli deleting Elevator Keys (from The War Within or Kuva Assault missions) if picked up while riding Merulina.
• Fixed Tauron Prime Regalia clipping into the neck on certain Drifter/Operator heads.

Fixes:

• Fixed an untintable square on the back of the Tauron Prime Regalia.
• Fixed offset issues with the Xairaks Armor pieces.
• Fixed Clients inconsistency hearing Vadarya Prime SFX.
  • Also polished the Vadarya Prime charging SFX.
• Fixed the Jotunheim Whip Skin's blade not taking energy tints.
• Fixed the Gauss Nitrolyst Skin's thigh pads clipping into Gauss' legs.
• Fixed tintmask bleeding on the Gauss Profitas skin.
• Fixed the Axi O7 not following proper naming conventions — it has now been renamed Axi Y2.
• Fixed players being unable to type a value below 20 in the FOV setting in Captura.
  • This originally was a bug, but we're adding it back as a feature as low-FOV is a staple in the Captura community.
• Fixed being able to copy and paste negative numbers into some setting sliders.
• Fixed Deimos Tier 2 and 3 Isolation Vault Bounties not properly displaying their location in the Codex.
• Fixed a script error related to Oraxia's Mercy's Kiss.
• Fixed a script error caused by Khora's Strangledome.
• Fixed a script error related to the Heavy Attack teleport from the Amar set mod bonus on Exalted Weapons.

Fixes:

• Fixed players receiving the TennoCon Riftguard Syandana (Void-Swept) with purchases of the Xikonos Syandana.
  • This was patched live at around ~1 p.m. ET!
  • We will be carefully removing the Riftguard Syandana from accounts who unintentionally received it (excluding those who already owned the TennoCon Digital Pack).
• Fixed the Vital Arbiter Nightwave Act being locked behind Steel Path access (instead of Arbitration access, as intended).
• Fixed dead Hosts not seeing the option to accept mission votes (notably in Railjack or Open Landscape missions).
• Fixed issues with the Vadarya Prime's VFX for Clients.
• Fixed the Vadarya Prime's sniper scope not being affected by the "Use Sniper Scopes" setting.
• Fixed the Vadarya Prime's charging VFX persisting if the charge is cancelled or weapons are swapped.
• Fixed some Syandanas clipping through Caliban Prime's exhaust cannisters.
• Fixed offset issues for the Xairaks Leg Armor on Hydroid.
• Fixed a script error related to Valkyr's Warcry.
• Fixed a crash related to Conclave Dedicated Servers.

UPDATE 39.1: CALIBAN PRIME

Update 39.1.0 is an interim Cert Update!

Meaning that we have put together a small collection of code changes and fixes to accompany Caliban Prime Access and TennoGen Factions.

If any of the terms above are new to you, visit The Warframe Lexicon for Updates to learn more about Warframe’s development cycle.

Update Download Size: ~0.24 GB

CALIBAN PRIME ACCESS

Caliban Prime

Forged in celebration of the all-too-brief peace between the Orokin and Sentients, Caliban Prime is a true collaborative masterpiece. The heir of twin kingdoms arises in royal gold.

Caliban Prime’s Lethal Progeny Conculyst, Ortholyst, and Summulyst summons are also adorned in gold!

Venato Prime

Fashioned from the willingly-donated bone of the Sentient Ur-Hatho and embellished by Orokin luxurator Sembik Vol, Venato Prime was to be wielded against “common enemies” of the united peoples – had any ever emerged from the darkness beyond Tau.

Vadarya Prime

Caliban Prime's signature sniper rifle is no mere ceremonial weapon. A sign, perhaps, that peace between Orokin and Sentient was destined to be fleeting. Struck enemies become lightning rods, with a chance to attract bolts of chain lightning that can jump to nearby enemies.

Caliban Prime Accessories

Neurovyre Prime Syandana

Painstakingly embellished with scavenged gold as a treaty gift for the Orokin, this Sentient spinal symbiote serves as Caliban Prime’s signature syandana.

Tauron Prime Regalia

The Tauron Academy uniform blends Tenno functionality with Sentient design.

Items Moved To Prime Vault

Now that Caliban Prime Access is available, the following items have been added to the Prime Vault for a future Prime Resurgence rotation. If you have Relics that contain these items they will remain in your Inventory.

• Grendel Prime
• Masseter Prime
• Zylok Prime

Riven Disposition Changes

As with each round of Prime Access come updated Riven Disposition numbers — check the full details here: https://forums.warframe.com/topic/1466761-august-2025-riven-dispositions/

TENNOGEN FACTIONS

A fierce new collection of community-made creations have arrived! Featuring a Corpus inspired Gauss skin, an Entrati themed Syandana, as well as Tenno inspired Armor and a Whip skin, TennoGen Factions bring several aesthetics of the Origin System to your Arsenal.

Gauss Profitas Skin

A unique skin for the Gauss Warframe, designed by malaya, Jadie, and Noxxr.

Xikonos Syandana

A syandana for your Warframe, designed by led2012 and daemonstar.

Whip Jotunheim Skin

A unique whip skin, designed by Mz-3.

Xairaks Leg Armor

A unique leg armor for your Warframe, designed by lex182 and cedd00.

Xairaks Chest Armor

A unique leg armor for your Warframe, designed by lex182 and cedd00.

CHANGES

• Teshin has a new "Steel Path?" conversation option for those who do not have The Steel Path unlocked. Selecting this option will list up to 3 planets with missions that are remaining, in addition to any Quest and Mastery Rank requirements that are missing.
  • We opted for a shorter list to make it easier for players to remember what nodes to work towards.
  • Quest and Mastery Rank requirements are now listed to guide players towards unlocking “hidden” nodes. (ex: Tyana Pass requires Mastery Rank 3 and the completion of The Heart of Deimos)
  • 
• The Fragmented Tide now takes damage based on the health of the Murmur killed in the The Fragmented fight, instead of the number of Murmur killed.
  • This change fixes the "Hostile Regeneration" Risk Variable in Deep Archimedea missions not properly applying to the Fragmented Tide's health.
    • Previously, killing one Murmur would immediately revert the Fragmented Tide's health to its pre-regeneration state (because it was counting how many Murmur were killed).
  • Murmur now spawn continually in this stage, as players no longer need to kill all spawned Murmur to progress to the second stage.
• Improved firing and pathing behaviour of the Ortholysts spawned by Caliban's Lethal Progeny.
• Improved lighting when customizing Operator/Drifter Facial Accessories in the Orbiter.
• Palladino's Kavat (Rook) in the Chains of Harrow Quest is now invulnerable, so players no longer have to worry about reviving them while also dealing with the existential horrors of this Quest.
• Providing Modular Items for Standing now prompts a confirmation screen so players don't accidentally donate their Amp or Moa without realizing it.
• Reduced the music from Daughter's headphones during the Heart of Deimos Quest.
• Added Tips to the Ayatan Treasures screen in the Mod Menu.
• Changed the "Complete the Advanced Movement Tutorial" Junction Task reward from 500 Rubedo to 500 Endo.
  • The Isleweaver patchnotes incorrectly listed the reward as 500 Endo, so we are updating it to match since new players often need Endo.

Dog Days Changes and Fixes:

• Players can now see how many Nakak Pearls they own in the currency bar when viewing Beach Toys at Nakak.
• Fixed Helminth Invigoration and Archon Shard buffs appearing in Dog Days missions, despite their effects not actually applying.
• Fixed "No Stance Mod Installed" pop-up appearing in the Pause Menu of Dog Days missions if opened with the Noodletron equipped.
• Fixed the Dog Days jingle playing in Railjack missions if started via the Dry Dock in a Relay.

TOP FIXES

• Valkyr Heirloom Skirt Tweaks and Fixes:
  • Made improvements to Valkyr Heirloom’s skirt cloth to prevent clipping into her legs.
  • Fixed some texture flickering on her skirt.
  • Fixed texture seams in the semi-transparent cloth on Valkyr Heirloom.
  • Also fixed the cloth not properly inheriting Emissive tints.
  • Known Issue: Further improvements to the cloth are needed, but require additional code changes that didn’t make it into this build.
• Valkyr Ripline Tweaks and Fixes:
  • Fixed Ripline being able to target dead enemies.
  • Increased the aim radius to make it more lenient and made it prioritize enemies.
  • Improved enemy grouping by Ripline, meaning it should be able to more consistently pull enemies that are further away.
  • Fixed the VFX lingering after cast for Clients.
  • Fixed a script error caused by Valkyr's Ripline.
• Fixed Finishers during Valkyr's Hysteria not triggering Lifesteal if a primary or secondary weapon was equipped when initiating the Finisher.
• Fixed Quick Return Mods causing Glaives to detonate after they bounce on walls.
• Fixed Companion Damage not being increased by the Hunter Mod set bonus when attacking enemies that are inflicted with Slash.
• Fixed the Incarnon forms for the Dera Vandal, Cestra, and Sicarus Prime not functioning as intended.
• Fixed cases of Kuva Lich and Sister of Parvos controlled nodes being able to be played with the mission's default enemy levels.
• Fixed the Amar Mod set bonus not triggering from Exalted Melee Weapons.
  • Now, Heavy Attacks will properly teleport players if performed with an Exalted Melee Weapon.
• Fixed a loss of function when pulled into the Undercroft while a player was kneeling at Rusalka's Shrine in Isleweaver.
• Fixed cases of Oraxia's Mercy's Kiss not properly executing enemies below the health threshold for Clients.
• Fixed Finishers being counted twice for Bounty Objectives.
• Fixed more cases of players being teleported into Oraxia's Lair if they fell off the map close to its location, often resulting in them getting stuck.
• Fixed bonus Status Effects from Cyte-09's Resupply, Reconifex's perfect reload, and Oraxia's Silken Stride not working with Multishot for Clients.

Warframe and Weapon Fixes:

• Fixed Simulor's projectiles being unable to hit ragdolled enemies if the Spontaneous Singularity Augment is equipped.
• Fixed Caliban's Razor Mortar Augment not properly triggering Archon Stretch.
• Fixed cases of players becoming stuck if they cast Wrathful Advance throwing the Wolf Sledge.

• Fixed the VFX Caliban's Fusion Strike not matching the modded Ability Duration.
• Fixed the spectral daggers spawned by the Okina's Incarnon Form not using player colors.
• Fixed the Eternal War Augment not triggering on kills from Atlas' Landslide, Gara's Shattered Lash, Khora's Whipclaw, and Ash's Shadow Clones.

Cosmetics Fixes:

• Fixed edge cases of Warframe attachments creating blocking volumes around the Warframe, causing them to get caught in the Arsenal.
• More fixes towards the tendrils on the back of the Hildryn Sarcostema Helmet to make them act more like hair, per the artist's request.
• Fixed the Aoi Gemini Emote using the wrong dialog lines.
• Fixed Nautilus Prime being unable to equip the base Nautilus skin.
• Fixed offset issues with the Latron Armor set on Grendel Prime.

UI and HUD Fixes:

• Fixed Numerical Separators setting of "1 000,00" causing Captura settings to start at 0, causing players to see a very darkened screen.

• Fixed Chipper's transmissions not being updated to match the 3 wave cadence of Defense missions in Archon Hunts.
• Fixed equipping a Focus Lens in a Dojo causing the Eris Junction Task to not progress.
• Fixed "Randomize All" and "Reset to Defaults" options in the Appearance menu using the same input for controllers.

• Fixed typing numbers into a slider setting causing the number to jump to max value, instead of the typed value.
• Fixed Set Mods not correctly displaying the set bonuses in Teshin's Cave in Duviri. (This was a UI-only issue!)

• Fixed Operators and Drifters being invisible in the Central Mall Backroom Scene.

• Fixed Client Drifters in the Duviri Experience returning to Duviri with Warframe weapons equipped if a Host Migration happened at a specific time.
