Controlling two Warframes as one might sound confusing, especially when they’re bickering brothers, but the playstyle for Sirius and Orion eventually boils down to committing war crimes against the galaxy. Luckily for us, the Geneva Convention is long gone in Warframe, which is great because we have simplified nuking enemies while absorbing them into a profane blob and denying their right to free will. In other words, our Sirius and Orion build is simple, effective, and awesome.
Sirius and Orion Build Explanation
Now, before we achieve this kind of rhythm with the brothers, you have to understand what makes this particular Warframe combo unique. Sirius and Orion each have separate mod slots and Arcane slots, meaning you have to build both. That also means you have to Forma each of them separately while also ranking up the mods, so the leveling process might get a bit tedious.
However, our build uses nearly the same mods for both Warframes, which lets you jump into the action using the full build quicker. This build will require four Forma, so eight, actually, since you’re building it for two Warframes. However, you can opt for non-Primed versions of the mods to save Forma and effort. And don’t worry about the playstyle, we’ll cover that later near the end. For now, focus on building up Sirius and Orion using these mods:
Mod List
| Sirius Mods | Orion Mods |
| Power Donation (Aura) | Corrosive Projection (Aura) |
| Cunning Drift / Power Drift (Exilus) | Cunning Drift / Power Drift (Exilus) |
| Umbral Intensify / Intensify | Umbral Intensify / Intensify |
| Primed Continuity / Continuity | Primed Continuity / Continuity |
| Primed Flow / Flow | Primed Flow / Flow |
| Transient Fortitude | Transient Fortitude |
| Overextended | Overextended |
| Blind Rage | Blind Rage |
| Stretch | Stretch |
| Augur Secrets | Augur Reach |
Orion generally benefits from more Ability Range, compared to Sirius. As always, feel free to change some mods around, but you should aim for around 200 percent Ability Strength and Range. We are a nuker build, after all. Also, do note that Aura mod effects don’t stack between the two Warframes, so pick a different one for each.
You will also need to subsume Sirius’ 2nd Ability and replace it with Rhino’s Roar. This buffs the build’s damage immensely, but if you don’t have that, then it’s fine, no need to fuss.
Arcanes for the Sirius and Orion Build
- Arcane Energize – On Energy Pickup: 60% chance to replenish 150 Energy to self and allies within 15m
- Molt Augmented – On Kill: +0.24% Ability Strength. Stacks up to 250x.
Archon Sirius and Orion Build
We recommend going with this combo:
- 4x Crimson Archon Shards (Strength)
- 1x Amber Archon Shard (Casting Speed) or another Crimson
You can replace the Amber Shard with another Crimson Shard for more Ability Strength. Ideally, everything should be Tauforged, but that’s an optional luxury.
Playstyle for the Sirius and Orion Build
Despite having their differences and having separate mod slots, these two brothers share the Archon Shards and also the 4th Ability. That’s what’s going to be doing the heavy lifting when it comes to nuking whole rooms. The 4th Ability, for the record, uses the stats of the Warframe that’s currently out and attacking, so you will want to be on Sirius once you’ve popped it off, since he has a bit more Ability Strength.
Additionally, you can easily switch to the other Warframe by holding Abilities 1,2, and 3. This hold maneuver not only switches to the Warframe, but also activates that Warframe’s ability based on the number you pressed. That’s something to keep in mind when pulling off the rotation.
- Switch to Sirius if you aren’t already.
- Use Sirius’ 2nd Ability (Roar if subsumed, if not, then the default is fine).
- Use Sirius’ 3rd Ability
- Hold-cast 3rd Ability to use Orion’s 3rd Ability (switch)
- Use Orion’s 1st Ability
- Hold-cast 1st Ability to use Sirius’ 1st Ability (switch)
- Use Sirius’ 3rd Ability again
- Hold-cast 1st Ability to use Orion’s 1st Ability (switch)
- Use the 4th Ability
- Repeat steps 1 to 9
- Make sure to pick up Energy Orbs that enemies drop
If you manage to maintain this rotation, you’ll be dealing millions of damage, leaving not much chance for enemies to get a hit in.
