Actions

Multiattack. The dragon can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +16 to hit, reach 4.5 m. Hit: 20 (2d10 + 9) piercing damage plus 11 (2d10) lightning damage.

Claw. Melee Weapon Attack: +16 to hit, reach 3 m. Hit: 16 (2d6 + 9) slashing damage.

Tail. Melee Weapon Attack: +16 to hit, reach 6 m. Hit: 18 (2d8 + 9) bludgeoning damage.

Frightful Presence. Each creature of the dragon’s choice that is within 35 meters of the dragon and aware of it must succeed on a DC 20 Will saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the dragon’s Frightful Presence for the next 24 hours.

Lightning Breath (Recharge 5–6). The dragon exhales lightning in a 25-meters cone or a 35-meters line that is 3 meters wide. Each creature in that area must make a DC 23 Reflex saving throw, taking 88 (16d10) lightning damage on a failed save, or half as much damage on a successful one.
