Belephaion makes three attacks: one with its bite and two with its claws.
Melee Attack Roll: +9 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) piercing damage plus 5 (1d10) lightning damage.
Melee Attack Roll: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage.
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.
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.
