Dark Energy Blast

This spell can only be cast with a staff.

As you cast the spell, your staff picks up hundreds of thousands of volts of dark energy, black and deep purple smoke gathers around the tip of your staff. The energy forms into a large sphere, and a as you say the final line of the spell, all the energy, smoke and darkness blasts at the target giving them a collosoll dark magic electric shock. The target takes one D20 damage.
