Thor's Wrath

Intense, immense electrical force flashes in a 60-foot radius of a point within range. Each creature within that boundary must make a Dexterity saving throw. On a failed save, a creature takes 12d6 lightning damage and is blinded for 1 minute. On a successful save, it takes half of that and isn't blinded. Creatures wearing or holding metal have disadvantage on this saving throw.

A creature blinded by this spell Constitution saving throws at the end of each of its turns. When it succeeds, it is no longer blinded.
