Build Constellation Stars on Orion with cheap Gravitic Slashes and Event Horizon, swap to Strength Sirius, open Celestial Clash, and match LMB/RMB to star colors. End on Sirius so he scoops Energy Orbs. The loadout grid is the Sirius Strength lead — keep a separate Orion config with Range/Efficiency for Star fill and grouping.

Sirius & Orion share one Warframe slot with two full kits and two separate mod configs. Swapping brothers grants 45% Ability Efficiency for the next two casts. Casting abilities fills Constellation Stars (no more than two of the same color in a row). Celestial Clash spends Stars for Blast nukes and inherits the stats of whichever brother starts the cast — open on your Strength lead. Duplicate auras on both configs do not stack.

• Sirius 1 Coronal Ejection — Jade Light scythe throw for Heat + pickup vacuum. Hold swaps to Orion's Gravitic Slash. Common Helminth slot (Roar).
• Sirius 2 Jade Stars — Heat motes that launch on attack. Motes still use Sirius Strength/Range/Duration even if Orion fires them.
• Sirius 3 Light's Sanctuary — Growing heal / revive / DR well. ~167% Strength hits the 75% ramp DR cap.
• Shared 4 Celestial Clash — Sky duel — spend Constellation Stars for Blast. Match LMB/RMB to star color for crit chance and escalating damage. Start on the Strength brother.
• Orion 1 Gravitic Slash — Slash strip / repel. ~200% Strength (or ~164% with Corrosive Projection) fully strips armor; cheap Star filler.
• Orion 2 Astral Shell — Shell that becomes an invulnerable taunt decoy on first hit.
• Orion 3 Event Horizon — Drifting black hole. Slash / Coronal hits extend and steer it; recast collapses for Heat.
• Keep Celestial Clash. Open Clash on Sirius. Partner Orion config: Range + Efficiency for Event Horizon / Gravitic Slash.

• Shared shards: Casting Speed
• Strength
• Flexibility for more Strength / Duration

Optional Roar over Coronal Ejection on Sirius. Keep Clash native.

• Steel Path Survival / Defense / Disruption

  Excellent

  Celestial Clash Blast chains under full Constellation Stars delete SP packs when opened on high-Strength Sirius after Orion strip/group.

• Mobile Defense / Excavation

  Excellent

  Horizon the point, strip, Clash.

• Exterminate / Capture Speed Runs

  Excellent

  Star fill into Clash clears tiles.

• Spy / Rescue / Nightmare

  Loud sky duel — not stealth.

• Open World / Bounties

  Strong

  Camp Clash works.

• Long-Range Gunplay / Eidolon-Style Content

  Situational

  Clash wants grouped packs.
