Rageful Nimbus (TP)

Choose a creature within range, which can be yourself. A pristine, fluffy white cloud appears above the target and follows them for the duration. If the target takes damage from a hostile creature you can see, you can use your reaction to make a ranged spell attack from the cloud, provided that creature is within 60 feet of the target. On a hit, the creature takes 2d8 lightning damage.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
