Whirling Weapon

You hurl a single melee weapon at your foes, magically striking at all enemies along a 30 foot line. Make a melee spell attack against each creature of your choice in a 30-foot line. On hit, the target suffers damage as if struck by the weapon with two hands, using your spellcasting ability modifier, instead of Strength or Dexterity, for the damage rolls. No matter how many targets your weapon hits or misses, it instantly and unerringly returns to your hand after attempting the last of its attacks.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the range of the spell by 30 feet for every slot level above 2nd. Additionally, when you cast this spell using a spell slot of 4th level or higher, the damage dealt by this spell becomes magic for the purposes of bypassing resistances, and gains a +1 bonus to attack and damage rolls made with this spell for each two slot levels above 2nd.
