Dark Cloaked Dimension Slash

You fire off a dark slash that can cut through dimensions from a weapon you are currently wielding. The slash is 5 feet wide and travels 100 feet in a line in a direction you choose. Each creature in the line must make a Dexterity saving throw, taking 8d8 dark damage on a failed save, or half as much damage on a successful one. If you cast this spell while inside of your Mana Zone, it deals an extra 10d8 dark damage.

The slash ignores all cover and cannot be blocked in any way other than distorting space. Additionally, it instantly cuts through and destroys any magical barriers in its way, such as a wall of force spell.

At higher levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
