Thunderstorm

5th-level transmutation (dragon)

Casting Time: 1 action
Range: Touch
Components: V, S, M (a piece of lightning-fused glass)
Duration: Concentration, up to 1 hour

You touch a willing creature, and it becomes surrounded by a roiling storm cloud 30 feet in diameter, erupting with (harmless) thunder and lightning. The creature gains a flying speed of 60 feet. The cloud heavily obscures the creature inside it from view, though it is transparent to the creature itself.
