Abilities
Judgment Cut (Recharge 5–6): As an action, you slash the air, creating rifts of cutting energy in a 30-foot cone. All creatures in the area must make a Dexterity saving throw (DC 18), taking 8d10 force damage on a fail, or half as much on a success. The area briefly warps and flickers with afterimages of your strike.
Dimensional Step (2x per long rest): As a bonus action, you can teleport up to 30 feet to an unoccupied space you can see. If you appear adjacent to a creature, your next melee attack against it before the end of your turn has advantage.
Sever the Veil: Once per long rest, you may cast plane shift (self only, no components) as you slice open reality.
Edge of Nothingness: The blade cannot be broken, and no magic can prevent its strikes from reaching their target short of divine intervention. This weapon ignores any slashing resistance.
