Lightning Breath (Recharge 5-6).

Belephaion exhales lightning in a 60-foot line that is 5 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 55 (10d10) lightning damage on a failed save, or half as much damage on a successful one.

Alter Shape.

Belephaion magically transforms into an eagle or a priest, while retaining his alignment, damage immunities, hit points, Hit Dice, and Intelligence, Wisdom, and Charisma scores. This transformation ends if he is reduced to 0 hit points or uses a bonus action to end it.
