Info

  • Light's Sanctuary is Sirius’s ability 3 on the Sirius & Orion dual kit.
  • Sirius creates a well of light that heals and revives allies, while reducing incoming damage.
  • 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.

Tips & Tricks

  • Park the well on the objective and let the 10 s ramp finish before the hard wave.
  • 167% Strength hits the 75% ramp DR cap; extreme Strength only helps the initial DR floor.
  • It can revive the controlled Sirius if he goes down inside the dome.
  • One sanctuary at a time — recast relocates rather than stacking zones.

Range

Efficiency

Base cost 50 energy — Efficiency plus swap passive keeps dual casting cheap.

Priority

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

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Light's Sanctuary still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Light's Sanctuary to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Light's Sanctuary only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Light's Sanctuary is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

Comparisons

  • VS

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