Animate Weapon

You touch a melee weapon with the light property that is in your possession, causing it to spring to life and float around you.

For the duration, once per turn on your turn when you make a melee weapon attack against a target within 5 feet, you can make a melee attack with the animated weapon as part of the same action, dealing damage equal to the weapon's damage dice + your spellcasting ability modifier. If you animate another weapon while you already have one active, the first weapon you animate ceases to be animated and falls to the ground.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, you can cast it on a melee weapon without the light property. If you cast this spell using a spell slot of 4th level or higher, you can instead create a Flying Sword (Basic Rules pg 128) with a duration of 24 hours. You can issue a basic 5 word or less command that sword will attempt to carry out for the duration of its existence; if you use a 7th level or higher spell slot to create a Flying Sword, the duration becomes permanent.
