Arcane Void

Draw on the Arcane Torrent to fuel the spell in addition to your own abilities. If you lack the Arcane Torrent(home-brew mechanic) then instead consume the magical properties of one magical item. By consuming the magical properties of one magical item you strip it of all magical bonuses(this does not stripped cursed items of their curse or effects). 

Doing so you are able to cast the Arcane Void

Choose an 5-foot cube of air that you can see within range. By focusing on the space between the Arcane Torrent and the material world you open a small tear between the two.

Any creature that begins its turn within 5 feet of the tear must make a Wisdom saving throw. On a failed save, the creature takes 2d10 force damage and cannot speak until the beginning of its next turn, while the creature can't speak it cannot cast spells that require verbal components.  On a successful save, the creature takes half as much damage and isn't silenced.

As a bonus action, you can cause a feedback loop in the tear. All creatures within a 5ft cube of the tear must make a Wisdom Saving Throw. On a failed save the creature gains a vulnerability to force damage for 1 hour. On a successful save, the creature is not affected and cannot be affected by the feedback loop for 24 hours.

Each use of this spell inflicts one level of exhaustion. These levels of exhaustion may be removed by draining the magical properties of a magical item. These levels of exhaustion can be removed by draining the magical properties of a magical item or a long rest.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
