Otiluke's Razor

6-level Transmutation

Casting Time: 1 Bonus Action

Range/Area: Self

Components: Verbal Somatic Material

Materials: A silver table knife worth at least 5 gold, which the spell consumes

Duration: Concentration, up to 1 minute

With the proper enchanting, even a simple table knife can be a powerful defense against trechery.
When you cast this spell, the knife used to cast the spell morphs into a razor-sharp dagger of force. You are proficient with the dagger, and when you attack with it, you may use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls. On a hit, it deals 2d4 piercing damage.
Once during the spell's duration, when you hit a creature with the dagger, you can invest the target with visions of the Far Realm. The creature you hit must make a Charisma saving throw. On a failure, you deal an extra 10d10 psychic damage and the target has disadvantage on all saving throws for 1 minute. The affected creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Available for: Warlock, Wizard
