Multiattack. The dragon makes one Bite attack and two Claw attacks.
Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 14 (2d10 + 3) piercing damage plus 4 (1d8) radiant damage.
Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.
Scintillating Breath (Recharge 5–6). The dragon exhales a burst of brilliant radiance in a 30-foot cone. Each creature in that area must make a DC 15 Constitution saving throw, taking 27 (6d8) radiant damage on a failed save, or half as much damage on a successful one. The dragon then gains 10 temporary hit points by absorbing a portion of the radiant energy.
