Teleport Slash

You conjure a sword made of ethereal light that seems to bend and twist space around it. Make a melee spell attack against a creature within range. On a hit, the target takes 3d10 force damage. Until the spell ends, you can make the attack again on each of your turns as an action. When you deal damage to a target with this spell, you can force the target to make a Constitution saving throw. If the save fails, the target is stunned until the end of its next turn.

At Higher Levels. When casting this spell using a spell slot of 4th level or higher, the damage of this spell increases by 1d10, and the range of this spell increases by 15 feet for each spell level above 3rd.
