Info

Coronal Ejection is Sirius’s ability 1 on the Sirius & Orion dual kit.
Hurl Sirius' Jade Light infused scythe, dealing Heat Damage while collecting any pickups in its path.
Holding most 1–3 abilities swaps control to the other son and casts their paired ability instead.
Constellation Stars from casts feed Celestial Clash — build stars before you need the nuke.

Throw through dense packs — enemies can be hit on the outbound and return path.
Use the pickup vacuum after big kills so orbs and ammo come back to the controlled son.
Hit Event Horizon to yank the black hole toward Sirius and extend its duration.
Hold-cast to swap into Orion’s Gravitic Slash when you need strip instead of Heat.

Strength: Strength scales Coronal Ejection’s damage and key effect values — mandatory on nuke/strip/heal paths.
Duration: Duration matters on Coronal Ejection when the ability is timed (buffs, zones, black hole, motes).
Range: Range grows Coronal Ejection’s hit radius, vacuum, or explosion — high priority for tile clear.
Efficiency: Base cost 15 energy — Efficiency plus swap passive keeps dual casting cheap.

Strength and Range first for clear; Duration for zones/shell/motes; Efficiency for long missions.

Mission	How to Use It
Steel Path Survival / Defense / Disruption	Test whether Coronal Ejection still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / Excavation	Use Coronal Ejection to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed Runs	Cast Coronal Ejection only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet Routes	If Coronal Ejection is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

VS
Vs similar tools on other frames — Coronal Ejection is tuned for Sirius & Orion’s loop — don’t judge it as a standalone subsume without the rest of the kit.
