Triple Take

You fire three small bolts of electricity out of you finger. They can be aimed at one target, or multiple. Each shot deals 1d8 lightning damage. If all 3 shots are fired at one target, the target is now stunned for one of it's turns.

If you do not want to fire all 3 projectiles in one turn, you may hold a shot until your next turn. You can also hold all of the shots for a turn and cast it again next turn. Keep note that you must charge the shots with one hand, and that hand may not be used for other things.

If you hold 6 charges for 3 rounds, then you may release a ton of energy in a 5 by 60ft ray, dealing 10d8 lightning damage.
