Dampi's Arcane Assault

A spell originally designed to allow Dampi to write approximately 250 percent faster, later altered to assault anyone who attempted to touch his hat.

5 spectral hands appear in a 5 foot space that you can see within range. The hands can share the space with another creature. As a bonus action the caster may have the spectral hands make a melee spell attack using the casters spellcasting modifier. The attack does 5d10 force damage. 

Additionally, creatures exiting the hands threatened square are subject to an attack of opportunity using your reaction.

At Higher Levels. For each level after 3rd add an additional hand to the swarm and an additional 1d10 damage.
