Time Knife
Casting Time: 1 bonus action
Range: Self
Components: V, S
Duration: Concentration, 1 minute
You summon into existence a knife that appears like a cutout in space around it. Once per turn, as a bonus action, you can use the knife to make a melee attack. Your modifier to hit is your spellcasting attack modifier. On a hit, the knife deals 1d10+your spellcasting ability modifier psychic damage. If you hit, the creature must make a saving throw against your spell save DC or be stunned until the end of your next turn as they behold the concept of time.
You can choose to throw the knife, in which case it has a 20/60 range. On a hit, you can use your bonus action the next round to recall the knife and deal another 1d10+your spellcasting ability modifier psychic damage and force the creature to make the saving throw again or be stunned.
At Higher Levels. If you cast this spell with a slot above 3rd level, another knife appears for every two slots above 3rd level. With your bonus action you can attack with each of these knives.
