Call of Talos

Surging blue runes begin to form on the ground around you as the skies above you churn with darkness and cackle with electricity, the air around you turns crisp, the hairs along creatures arms begin to stick up. A brief silence sweeps 200 feet around the designated area as Talos himself heaves a massive arc of Lightning onto the designated point, smiting any creature in a 30 foot cylinder centered around any point you can see, sending a resounding crack audible 500 feet in every direction. creatures within the cylinder that have 100 hit points or less are disintegrated instantly, if a creature has more than 100 hp it must make a dc 20 constitution saving throw. Upon failure the target takes 9d12+50 lightning damage, a successful save takes half damage. If a target drops to 0 hit points during the spell, it is disintegrated, leaving a black smudge on the scorched earth below. If a target survives the initial blast, it is stunned for 1 minute. The effects of this spell add two levels of exhaustion. You can cast this spell again after 3 long rests.
