Void's Edge

This deadly Dunamancy folds space-time into an invisible edge, with a subtle flick of your wrist. After your action it fades to nothing.

Make a melee spell attack:

• On hit deal 1d12 magical slashing damage.
• At higher levels the number of attacks you can make with this blade as an action increase, at 5th level make two attacks, 11th level three, and 17th level four.
