Deep Arrow

You create a watery arrow in your hand that is cool to the touch and hurl it to a single target, if they are hit they take 4d8 force damage and they need to make a constitution save against your spell D.C. if they failed they are under what is called The Aura of the Deep

-each turn they are enchanted with the Aura of the deep they must make a constitution save against your spell D.C, if they fail water starts to fill their lungs and it counts as a minute under water. However things that don't need to breathe, or can breathe under water are not affected by the Aura of the Deep.
