Animate Blades

You animate a number of unattended objects, causing
them to levitate in the air and strike at targets you designate
of their own accord. Each object must weigh 10
pounds or less, and you can animate a number of objects
equal to 2 + your spellcasting ability modifier.
When you cast the spell you can move each controlled
object up to 50 feet and make one attack with it. You can
concentrate multiple objects on one target or divide the
objects among multiple targets.
Weapons you control strike with an attack bonus equal
to your spellcasting ability plus your level bonus, and deal
normal damage (for example, a dagger strikes for 1d4
piercing damage). Improvised weapons such as fist-sized
stones, heavy branches, or even sturdy bottles deal 1d4
bludgeoning, piercing, or slashing damage as appropriate.
If you roll a natural 1 when attacking with a weapon
or object in this manner, that object is “dropped” and you
can no longer control it with this spell.
As a bonus action in subsequent turns, you can cause
the animated objects to move and attack again.
The most common use of animate blade is to animate
the daggers and swords of fallen warriors found on
a battlefield or in a crypt; hence the name. However,
the magic of the spell does not discriminate between
blades, cudgels, rocks, or other potential weapons of the
right size.
At Higher Levels. When you cast this spell using a spell
slot of 4th level or higher, increase the number of objects
you animate by 2 for each slot level above 3rd.
