How to Get Acceltra and Akarius in Warframe (2026): Demolishers on Ur, and the Primes
Demolishers on Ur, one blueprint in forty
Last Updated on September 11, 2026
The short answer
Both blueprints drop from the Demolishers in the Infested Disruption on Ur, Uranus, each at about one kill in forty, rolled separately. Expect a long session or a few. The Prime versions are vaulted right now, so the base weapons are the practical 2026 route; both are still good, and Gauss makes them better.

| Weapon | Where | Odds |
|---|---|---|
| Acceltra | Demolishers on Ur, Uranus (Infested Disruption) | About 2.5% per Demolisher |
| Akarius | Same Demolishers, separate roll | About 2.5% per Demolisher |
| Acceltra Prime, Akarius Prime | Void relics, currently vaulted | Prime Resurgence or trading |

What you need first
| Requirement | Why |
|---|---|
| Ur on Uranus | The Infested Disruption node; clear Uranus to reach it. |
| Hexenon | Both weapons need it to build; it drops on Jupiter tiles. |
The farm, step by step
- Load Ur on Uranus. Kill enemies for Disruption keys and slot one into a conduit.
- A Demolisher spawns and walks toward the conduit; kill it before it arrives.
- Every Demolisher kill rolls Acceltra and Akarius separately at about 2.5% each.
- Loot boosters like Desecrate, Pilfering and Chesa do not work on Demolishers; bring damage, not loot frames.
- Stay for rounds rather than extracting; each round is four Demolishers.
- Gather Hexenon, Neurodes, Plastids or Polymer Bundle and Nano Spores, then build each in a day.
Best frames
| Frame | Role | Why |
|---|---|---|
| Gauss | Signature | Both weapons are Gauss's: sprint reloads and his kit make them sing. |
| Nova | Demolisher killer | Slow Molecular Prime holds the Demolisher off the conduit. |
| Saryn | Disruption clear | Spores clear the trash so the keys keep coming. |
Best weapons
| Weapon | Why |
|---|---|
| Acceltra | Fast full-auto rockets; reload speeds up while sprinting, which is Gauss's whole thing. |
| Akarius | Dual homing micro-rockets with radial damage. |
| Acceltra Prime | The Prime with better stats; relics come back with Prime Resurgence. |
| Akarius Prime | Same story; trade or wait for the rotation. |

WARFRAMETips that save runs
- The Demolisher nullifier pulse strips buffs; kill it with weapons, not abilities.
- Four Demolishers per round; a 40-minute session averages one blueprint.
- Both are self-stagger launchers: Primed Sure Footed or Cautious Shot.
- If you own the relics, the Primes are straight upgrades; if not, do not wait.
Mistakes that waste runs
- Bringing a Nekros for the drop; loot abilities do not touch Demolishers.
- Extracting after one round.
- Hunting Acceltra Prime relics in fissures while it is vaulted.
