Call The Void

A vortex of dark energy forms with a width of 10 feet, centered on any point within range. A creature or object within 5 feet of the vortex must make a dexterity saving throw, with a DC of 15, or be pulled into it (On a success, they are forced 10 feet away from it). Anything inside of the vortex, or just barely got pulled inside the vortex, must take a constitution saving throw with a DC of 10 + level of caster. On a failed save, the creature or object takes [roll]2d12[/roll] necrotic damage or half as much on a success. You can use an action to more the vortex 10 feet or end the spell. Anything within the vortex when the spell ends takes casters level times 50.
