Blade of chaos

You evoke a chaos blade in your free hand. The blade is similar in size and shape to a scimitar, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action.

You can use your action to make a melee spell attack with the Chaos blade. On a hit, the target takes 3d6 chaos damage and it must make a Constitution saving throw on a fail voices take over their head and make them terrified of you on and nothing on a successful one.

The chaotic blade sheds blood red and void black light in a 10-foot radius and dim light for an additional 10 feet.
