Varu'un's Dagger

A dagger rises up, bending at the will of you, the caster. It jerks and sways, rising in the air at your command.

You summon a floating dagger, which you control. On your next 10 turns, you can move or make an attack with the dagger as a bonus action. It can fly 30 ft, and deals 1d4 piercing and 1d4 force damage, magical for the point of overcoming resistances. If the dagger ever gets more than 60 ft from you, it vanishes.

At 7th, 14th and 17th level add another dagger. All daggers can attack on the same bonus action.

"a dagger at high speeds is as powerful as a bolt of fire or blast of eldritch power"-Varuun
