Bombing Raid (Costs 1 Action). With a flap of it's mighty wings, the Bazelgeuse takes to the skies and appears to fly off away from the fight. In actuality, a few moments after liftoff, scales will begin covering a a 30ft-radius circle and when sufficiently covered, the Bazelgeuse will then use

Explosive Landing (Costs 1 Action). The Bazelgeuse comes crashing down out of the sky, directly into it's designated target. The target must succeed a DC22 DEX save or take 8d8 Bludgeoning and 4d8 Fire damage on a failure. On a success, the target does not receive the bludgeoning damage, but still takes the fire damage. All targets in that 30ft-radius circle must also succeed on a DC20 DEX Save or receive 4d8 Fire damage, with half as much on a success.
