Lightning Nimbus

3rd-level evocation (druid)

Casting Time: 1 action

Range: Self

Components: V, S, M (fulminar’s whisker)

Duration: 10 minutes

For the duration, bolts of lightning course around your body, shedding bright light in a 5- to 20-foot radius and dim light for an additional number of feet equal to the chosen radius. You can alter the radius as a bonus action.

In addition, whenever a creature within 5 feet of you hits you with a melee attack, the creature receives a jolt from the lightning and takes 2d4 lightning damage.

You can end the spell early by using an action to dismiss it.
