Shed. Whenever the bazelgeuse makes a melee weapon attack it dislodges an explosive scale which lands in an unoccupied space with 5 feet of the bazelgeuse.

Fire Breath (Recharge 5-6). The bazelgeuse exhales fire in a 15-foot cone. Each creature in that area must make a DC 13 Dexterity saving throw, taking (2D8) fire damage on a failed save, or half as much damage on a successful one.
