Successor of the Void

You've spent your pass time studying the teachings that embodiment of The Void has left behind, and gain understanding of its seemingly randomness. By similating yourself with its remanant, you are able to draw its power at an expense.

As an Action. You partially become one with the nothingness for the next minute. For that duration your melee attacks with a weapon or an unarmed strike have their reach increase by additional 10ft. In addition, you become incapable of speech, cannot understand any spoken languages, comprehend any writings, and have disadvantage on all Charisma checks. You can use this feature once per long rest.

When you make a melee attack, you can choose to gain additional 1d4 to their damage roll. If you do so, you substract your Charisma score 1 until you Long rest. You cannot use this part of the feat if your Charisma score is 1.
