Sirius & Orion — Celestial Clash
Endgame build. Generate mixed-color stars, take the sky, spend them. August 2026 forced Heat on Clash — Archon Vitality and Heat inherit now apply. Match star color to the brother's paint for crit.

Wrong drop or mechanic?
Don’t build this yet
First Swap first
This loadout sits at Endgame. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.
Open First SwapWhy this build?
Endgame for endgame / endurance clumps, the reason the dual-frame exists, anyone done learning the hold-to-swap
Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.
- Celestial Clash is the dual-frame. Everything else exists to print stars and survive the landing.
- Color matching is free crit. Ignoring it is a self-nerf.
- Helminth Roar is a different loadout because Clash silences subsumes mid-duel.
Don’t use this for: Star Chart only · new accounts
Specialised investment for hard content
You don’t need the shards to run the loop. They are a later ceiling, not a gate.
Bring: Stars are the ammo — Clash is not an exalted grid. It spends Constellation Stars you baked with 1/2/3. Strength is the collateral. Color-matching is the crit. Heat inherit primers (Sobek, Epitaph) feed the Aug 2026 forced Heat.
Alternative if…
- Star Chart only → First Swap
- New account or low investment → First Swap
- This is too much Forma / cost → Celestial Clash — Optimised

Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current
Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.

Duel loop
Pocket card. Stick this on a second screen; the long version is the mission below.
- 1Bake stars: tap Sirius 1/2, hold-swap, Orion 1/2/3. Alternate colors. Watch the meter — two identical colors in a row is a wasted slot.
- 2Celestial Clash (4). You both take the sky. Left fire is Sirius, right fire is Orion. Spend a star per attack.
- 3Match the star's color to the brother you are attacking with for the crit bonus. The UI is a duet, not a death ball.
- 4You cannot Roar (or any subsume) during Clash. Buff before 4, or skip buffs on this config.

Common mistakes
