Magic Resistance. The dragon has advantage on saving throws against spells and other magical effects.
Magic Weapons. The Dragon's weapon attacks are magical.
Mythic Lightning. The incredible power of this creature's lightning is more powerful than the strongest enchantments. Characters who are normally immune to lightning damage instead are treated as if they are resistant to the lightning damage caused by this dragon and characters who are resistant to lightning damage instead treat it as if they were not. Characters who are not resistant to lightning damage are treated as if they were vulnerable to it.

Spell Immunity. The dragon is immune to all spells of 3rd level or lower.
Siege Monster. The dragon deals double damage to objects and structures.
Static cling. When a character makes a successful melee attack against the dragon, its Lightning Aura ability increases in damage by 1d10 (to a max of 6d10) for the remainder of the round.
Multiattack. The dragon can use its Frightful Presence. It then makes five attacks: one with its bite and four with its claws.
Bite. Melee Weapon Attack: +20 to hit, reach 15 ft., one target. Hit: 32 (4d10 + 10) piercing damage plus 13 (2d12) lightning damage + DC 20 Strength Saving throw or be swallowed. At the start of each turn, all swallowed characters suffer 23 (5d8) bludgeoning, 14 (3d8) acid, and 14 (3d8) lightning damage.

Frightful Presence. Each creature of the dragon's choice that is within 240 feet of the dragon and aware of it must succeed on a DC 26 Wisdom saving throw or become frightened for 1 minute. A creature that is frightened is also paralyzed. A creature of CR 10 or lower who becomes frightened in this way suffers a heart attack, instantly dropping to 0 HP and falling unconscious. A creature that would be made immune to fear through magic instead receives an advantage on its saving throw. 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.
