Warframe – Heart of Deimos: Prime Vault: 29.2.0 Patch Notes

Heart of Deimos: Prime Vault: 29.2.0


Prime Vault: Ember & Frost Prime
Add dueling elemental forces to your Arsenal with the latest Prime Vault release!

Ember Prime and Frost Prime, as well as their Prime Weapons and exclusive Customizations are now available for a limited time! Trinity Prime Packs, Nova Prime Packs, and their Relics have returned to the Vault.

Ember Prime, Frost Prime, Latron Prime, Reaper Prime, Sicarus Prime, and Glaive Prime Relics have been added back to the droptables!





Note: As some of you have noticed, our Prime Vault rotation this round has gone on a little long. We had to put a lot of work into making Deimos a simultaneous release during COVID times, and that meant we had to divert focus and people away from some other items. Prime Vault was one of those items.

This means the next Prime Vault offering is a tried and true debut of Ember and Frost Prime (full details to come tomorrow). It also means that we are now in a position to make the Vault following Ember and Frost Prime offer new-to-Vault contents because we recognize how important this is.

Thank you for understanding!

Marked For Death Changes:

We are changing Marked for Death to start its base Damage at 75%, which will cap at 150% with Mods. Since the ‘Damage Type In = Damage Type Out’, this will scale well with certain Damage types, specifically ones with DOTS which is what we envision.

Simply put: We’re bringing the damage back up!

Railjack Resources:

There will be a reduction in the batches of Railjack Resource Costs across the board required to yield Helminth Secretions.

The changes are as follows:

Resource Pre-Hotfix Batch Post-Hotfix Batch Reduction as a %
Asterite 5,000 1,500 30.00%
Aucrux Capacitors 25 10 40.00%
Bracoid 1,000 200 20.00%
Carbides 10,000 2,500 25.00%
Copernics 15,000 4,000 26.67%
Cubic Diodes 12,500 7,000 56.00%
Fresnels 1,000 150 15.00%
Gallos Rods 300 175 58.33%
Isos 400 200 50.00%
Kesslers 300 100 33.33%
Komms 25 15 60.00%
Nullstones 225 50 22.22%
Pustrels 15,000 5,000 33.33%
Titanium 20,000 10,000 50.00%
Trachons 10,000 1,000 10.00%


Additionally, anyone with Helminth installed and Railjack owned will receive an Inbox of Resources after the Hotfix goes live that includes the reduced costs. A perfect script is not possible, but a generous grab bag is! If you meet the criteria, you will receive the Resources via Inbox after the Hotfix date. We’ll let you know in this thread once the Inbox script has completed – stay tuned! Helminth Railjack Resource Inbox Script has finished!



To give players more options for the Bile Secretion, we are adding the following components as feedable to Helminth to create Bile:

  • Antiserum Fragment x 900
  • Javlok Capacitor x 7
  • Nav Coordinates x 65*


General Helminth Changes:

  • Helminth now shows you a locked status when you sit in the chair with a Warframe whose ability you’ve already Subsumed (stops player confusion).


Character Shader Changes:
We have made significant enhancements to probe-based lighting. The results of this are dynamic objects receive better quality lighting, and metals are more responsive. Additionally, objects should now look more grounded in their environments.
