Vortex Bolt

You charge yourself with the power of the storm, and your clothes begin to subtly flutter by an unseen wind.

When you cast this spell, and as an action on each of your turns until the spell ends, you can fire a bolt of lightning at one creature you can see within range.

The target must make a Dexterity saving throw. On a failed save, the target:

• The target takes 3d4 lightning damage, and has its speed reduced to 0 until the end of its next turn as its muscles seize up.
• It also takes 3d4 bludgeoning damage as a tight vortex of wind rushes down the path of the bolt, and pushes the target 5 feet away from you in a straight line.  This push has no effect if the target is more than one size larger than you.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, both the lightning damage and the bludgeoning damage increase by 1d4 for each slot level above 3rd.
