Ley Storm

A roiling stormcloud of ley energy forms, centered around a point you can see and extending horizontally to a radius of 360 feet, with a thickness of 30 feet. Shifting color shoots through the writhing cloud, and thunder roars out of it. Each creature under the cloud at the moment when it's created (no more than 5,000 feet beneath it) takes 2d6 thunder damage and is disruptive aura spell. Rounds 5-10. Flashes of multicolored light burst through and out of the cloud, causing creatures to have disadvantage on Wisdom (Perception) checks that rely on sight while they are beneath the cloud. In addition, each round, you trigger a burst of energy that fills a 20-foot sphere centered on a point you can see beneath the cloud. Each creature in the sphere takes 4d8 force damage (no saving throw). Special. A geomancer who casts this spell regains 4d10 hit points.
