Valkarion, The Endless Storm

Mythic Trait – Storm Rebirth (1/Day)

When Valkarion is reduced to 0 hit points, he doesn't die. Instead, he explodes into a vacuum of air. At the end of that round, he reforms in mythic form with 400 HP, shedding all conditions. His mythic actions become available.

In this form, Valkarion becomes an incarnation of sky and wind. His wings become living jetstreams, and his presence bends light and gravity. His voice becomes stormquake thunder, and he hovers effortlessly, reshaping weather and air with thought alone.

Atmospheric Supremacy

Spells with verbal components fail within 60 ft. unless the caster succeeds on a DC 25 Constitution saving throw.
Ranged attacks made beyond 90 ft. automatically miss.
Flying creatures within 300 ft. must succeed on a DC 22 Dexterity saving throw or fall prone and take 3d6 bludgeoning damage
