74 / 740 remainingRank 30 · Orokin Reactor · 60 base + 14 aura capacity
ABILITIES
Sirius and OrionPASSIVE Swapping between Sirius and Orion grants 45% Ability Efficiency for the next 2 casts. When below 50 energy, they steal energy from each other.
Coronal Ejection
Hurl Sirius' Jade Light infused scythe, dealing Heat damage while collecting any pickups in its path. (HOLD) Swap to Orion and cast Gravitic Slash.
Jade Stars
Sirius conjures Jade Light motes that slowly regenerate over time. Attacking enemies launches the motes, dealing Heat damage. (HOLD) Swap to Orion and cast Astral Shell.
Light's Sanctuary
Sirius creates a well of light that heals and revives allies, while reducing incoming damage. The well slowly grows in size and power. (HOLD) Swap to Orion and cast Event Horizon.
Celestial Clash
Sirius and Orion take to the skies in a cosmic clash. Each attack consumes a Constellation Star to inflict colossal Blast damage. Match the star color for increased Critical Chance.
CEPHALON FIELD GUIDE
How to play this build.
Tenno. Sirius and Orion are one Warframe you swap between. Build up Constellation stars by casting, then enter Celestial Clash and alternate left and right click to fire a chain of hits that alternate between the brothers. Make Sirius permanently invisible with the Shade bug so Arcane Crepuscular's crit multiplier is always on him, keep Roar up, and strip with Orion before you commit the combo.
The build (Sirius)
- Blind Rage, rank 10, aura slot - Umbral Intensify, rank 10, unpolarised - Equilibrium, rank 10, Naramon polarity - Archon Vitality, rank 0, Vazarin polarity.
Doubles Celestial Clash heat procs - Transient Fortitude, rank 10, Madurai polarity - Stretch, rank 5, unpolarised - Primed Continuity, rank 10, Madurai polarity - Primed Flow, rank 10, Naramon polarity - Aura: Corrosive Projection, aura slot - Exilus: Power Drift, unpolarised - Arcanes: Arcane Crepuscular, Molt Augmented
Arsenal figures land at roughly 313% Strength, 128% Duration, 145% Range, 45% Efficiency, with about 627 health, 455 shield, 160 armor and a 712 energy pool.
How it works
Celestial Clash damage is boosted by Roar, Arcane Crepuscular (30% Strength and a flat +3 crit multiplier), and ability-damage shards; it is not affected by Nourish, Tenacious Bond, Arcane Hot Shot or Vigorous Swap.
Since Aug 2026 Sirius forces a heat proc on Clash, so Archon Vitality (rank 0) doubles it and heat-inherit priming applies.
Umbral Intensify beats Precision Intensify on Sirius because Strength also feeds Roar, which double-dips the heat proc.
Every form swap gives 1.5s of invulnerability and every Clash attack gives ~0.6s, so you chain i-frames while comboing.
Playstyle (Orion's Belt combo)
Default controls, invisibility locked on Sirius.
1.
Starting in Sirius, tap 1 twice to build stars.
2.
Hold 1 to swap to Orion and strip enemies in front (viral primer optional here).
3.
Enter 4 and click Right, Left, Left.
4.
The last hit is Sirius at max damage and leaves you on Sirius to repeat.
Lazy mode: invert controls, tap abilities to build stars, then alternate clicks in Celestial Clash.
Duration, Efficiency, Range, Strength
Duration mostly for Roar on Sirius.
Efficiency covered by the passive (+45% on the two casts after a swap) plus Equilibrium.
Range: Stretch gives 37m and Clash is line-of-sight with a 26m base, enough for most rooms.
Strength is the priority, double-dipping on Sirius.
The mods
Blind Rage, Transient Fortitude, Umbral Intensify are the Strength.
Primed Continuity holds Roar.
Stretch is Range.
Primed Flow, Equilibrium are the energy base.
Archon Vitality doubles the heat proc.
Corrosive Projection helps the strip against overguarded enemies Orion cannot strip.
Orion's differences
Growing Power or Power Donation aura, Augur Reach over Primed Continuity, Overextended over Equilibrium, Augur Secrets over Archon Vitality, Arcane Energize over Molt Augmented.
Orion needs only 200% Strength to full-strip with Gravitic Slash.
Helminth
Roar subsumed onto Sirius's 3 (so Jade Stars stays for a weapon platform).
It buffs both frames and double-dips the heat proc.
You cannot cast anything while in Celestial Clash, so only duration-based buffs work.
Arcanes
Arcane Crepuscular (needs the invisible brother), Molt Augmented for Strength.
Arcane Concentration for Roar uptime, Arcane Energize for economy, as swaps.
Focus
Madurai for Strength and cast speed.
Any works.
Weapon synergy
A Shade with Duplex Bond and Tazicor holds the invisibility bug and AoE-primes viral and magnetic.
A heat-inherit primer (Epitaph, Kuva Nukor) before entering 4, or a Tazicor for passive heat inherit.
Staying alive
Chained i-frames from swaps and Clash attacks, plus shield gating, plus one brother permanently invisible, plus Orion's Astral Shell negating a hit on both.
It fails if you stop comboing with the gate down.
Energy
The swap passive plus Equilibrium plus Arcane Energize shared across both frames.
Where it struggles
The two-frame management plus combo order plus the invisibility bug is the steepest setup of any frame here.
Later combo hits do less because you cannot re-strip mid-Clash.
Bosses.
Variants
A dedicated weapon-platform Roar setup.
An Orion-primary config.
Strengths and weaknesses
Strong: strong burst combo, near-constant i-frames, two frames of utility, self-buffing.
Weak: very high complexity, combo damage falls off across hits, boss-blind, needs a Shade.
Who runs this
Players who want the most mechanically involved frame in the game and will learn the combo order to make it sing.

Gravitic Slash
Repel enemies with Orion's scythe, dealing Slash damage while reducing shields and armor. (HOLD) Swap to Sirius and cast Coronal Ejection.
Astral Shell
Envelop Orion in an Astral Shell. Upon taking damage the shell becomes a decoy that draws fire until it is destroyed. (HOLD) Swap to Sirius and cast Jade Stars.
Event Horizon
Orion forms a drifting black hole, trapping enemies within its gravity. Hitting the black hole with Gravitic Slash or Coronal Ejection extends its duration and changes its trajectory.
Celestial Clash
Sirius and Orion take to the skies in a cosmic clash. Each attack consumes a Constellation Star to inflict colossal Blast damage. Match the star color for increased Critical Chance.
