Mod it, do not build around it. Deth Machine Rifle Prime comes free with Dethcube Prime: 100 rounds of Slash at 10 fire rate, 10 percent crit, 4 percent status. Flat damage and elements only; crit and status mods do nothing here.
Comes with Dethcube Prime; with Energy Generator and Vaporize on the sentinel, the rifle is the least important thing about it.
The Deth Machine Rifle Prime is the signature weapon of the Dethcube Prime Sentinel. It is a direct upgrade to the regular Deth Machine Rifle.
This weapon primarily deals Slash damage, but its overall damage output is very low due to its poor critical and status statistics.
Introduced in Update 25.8, it received a rebalance in Update 37, which increased its base damage but did not address its fundamental scaling issues.
How to get the Deth Machine Rifle Prime
- Deth Machine Rifle Prime comes with Dethcube Prime: build the sentinel and the weapon arrives with it. Dethcube Prime is vaulted: open relics you already own, buy them for Aya when Prime Resurgence lists it, or buy the sentinel parts for platinum.
- Systems: Lith B8, Lith S10, Meso T6, Neo E2, Neo G2 and 3 more (vaulted relics).
- Carapace: Lith M6, Lith T4, Lith V9, Meso L1, Meso R3 and 3 more (vaulted relics).
- Cerebrum: Lith D2, Meso D4, Meso D6, Neo A7, Neo D2 (vaulted relics; the rare slot in Lith D2, Meso D4).
- Blueprint: Lith D1, Lith D3, Lith D4, Neo D3, Neo D6 (vaulted relics; the rare slot in Lith D1, Lith D3).
- Run the fissure tier that matches each relic, refine the rare part’s relic to Radiant, and pick the best of the four results with a squad.
- Build the sentinel parts, then Dethcube Prime; the Deth Machine Rifle Prime is in the sentinel’s blueprint, with its own slot and no extra crafting.
Check the Relic finder for live odds; the set price on this page is what the built Dethcube Prime set trades for on warframe.market. The weapon itself is untradeable.

The Deth Machine Rifle Prime has a very high Riven disposition of 1.455, indicating its low base power. This high disposition can make Rivens for it quite powerful, but even with a strong Riven, the weapon’s base stats are a significant hurdle.
Builds
Flat damage: Serration, Heavy Caliber and Split Chamber, Vigilante Armaments for multishot, Stormbringer and Infected Clip for Corrosive, Hellfire and Primed Cryo Rounds for the rest of the damage.

Sentinel weapons take no weapon arcanes. The sentinel itself takes companion arcanes, and the precepts on the sentinel matter more than this gun.

Pros and Cons
Pros
- Automatically acquired with Dethcube Prime
- High Riven disposition
- Primarily deals Slash damage
- Large magazine capacity
- Fast fire rate
Cons
- Ten percent crit and 4 percent status: nothing to scale
- Twenty base damage
- Does not matter at high level; Dethcube does
The Deth Machine Rifle Prime is a foundational sentinel weapon that struggles to keep pace with the demands of modern Warframe content. Its abysmal critical and status chances prevent it from being a viable damage dealer, even with its high Riven disposition. It serves primarily as a placeholder weapon for Dethcube Prime, with its main utility being the companion itself rather than the weapon’s direct combat effectiveness.
