Blessing of Takhisis (Mythic Trait, recharges after a Rest).
If the dragon would be reduced to 0 hit points, its current hit point total instead resets to 360 hit points, it recharges all of its abilities, its "Mythic Traits" activate and it can now use "Mythic" Legendary Actions for 1 hour.
Electrifying Aura (Mythic Trait).
At the start of the dragon's turn, the dragon can force any number of creatures of its choice within 60 feet of it to make a DC 17 Constitution saving throw. On a failed save, a creature takes 14 (4d6) lightning damage and is frightened
of the dragon until the start of its next turn.
The dragon can use the following Dragon Tactics
: dive, multi-claw, snatch, strafing, tail sweep, wing buffet
Scion of Lightning.
Lightning damage inflicted by the dragon ignores lightning resistance and immunity of creatures with 21 hit dice or less.
The dragon makes two claw attacks. It can replace one of this attacks with a Thunderbolt attack.
Bite. Melee Weapon Attack:
+15 to hit, reach 15 ft., one target. Hit:
34 (4d12 + 8) magical piercing damage plus 13 (2d12) fire damage and, if the dragon wishes, the target must make a DC 23 Strength throw or be grappled. A Medium or smaller creature grappled this way is also restrained.
Claw. Melee Weapon Attack:
+15 to hit, reach 10 ft., one target. Hit:
26 (4d8 + 8) magical slashing damage and, if the dragon wishes, the target must make a DC 23 Strength saving throw or knocked prone or pushed 10 feet, the dragon's choice.
Horn. Melee Weapon Attack:
+15 to hit, reach 15 ft., one target. Hit:
30 (4d10 + 8) magical piercing damage plus 11 (2d10) lightning damage. If the dragon has advantage on its attack roll, and both rolls hit, the attack is a critical hit.
Tail. Melee Weapon Attack:
+15 to hit, reach 40 ft., one target. Hit:
42 (6d10 + 9) magical bludgeoning damage. If the target is a Large or smaller creature, it must succeed on a DC 23 Strength saving throw or be knocked prone and stunned until the end of the dragon’s next turn.
The dragon beats its wings. Each creature within 40 feet of the dragon must succeed on a DC 23 Strength saving throw, taking 18 (4d4 + 8) bludgeoning damage and be pushed 10 feet on a failed save, or half as much damage on a successful one. The dragon can then fly up to half its flying speed without provoking opportunity attacks.
Thunderbolt. Ranged Weapon Attack:
+15 to hit, range 200 ft., one target. Hit:
22 (4d10) lightning damage and must make a DC 23 Constitution saving throw or be deafened.
