Repel enemies with Orion's sinister scythe, dealing Slash Damage and Status Effect while reducing shields and armor. (HOLD) Swap to Sirius and use Coronal Ejection.
Envelop Orion in an Astral Shell. Upon taking damage the shell becomes a decoy that draws fire until it's destroyed. (HOLD) Swap to Sirius and use Jade Stars.

Hitting the black hole with Gravitic Slash or Coronal Ejection will extend its duration and change its trajectory: Gravitic Slash will direct it away from Orion, and Coronal Ejection will pull it towards Sirius. (HOLD) Swap to Sirius and use Light's Sanctuary.
