Odeen's Magic Cloud

The caster creates a cloud that fills a five-foot cube at any point within range. They may freely move the cloud at a speed of 40 feet per turn as a bonus action. When concentration is no longer maintained, it drifts on the wind. Its area is lightly obscured.

When the cloud is created, its caster must choose one of four options for its composition:

Misty Cloud: The caster directs the cloud to cover a small area on the ground, typically around an object or creature. This cloud's area becomes heavily obscured.

Storm Cloud: The caster creates a personal storm cloud directly over their target. At the beginning of each round, this cloud unleashes a bolt of lightning directly to their head. The target must make a Dexterity saving throw or take 1d6 lightning damage on a failure.

Rainy Cloud: This cloud produces a very light drizzle. It may be used to water a garden or take a shower, but it does not produce enough rain to cause a flood. If this spell is cast over a creature that has the Water Susceptibility trait, such as a fire elemental, it takes 1 point of cold damage at the start of each of its turns.

Rainbow Cloud: This cloud emits anywhere up to five small, glorious rainbows.
