5th-level Spell: Summon Poltergeist Swarm

Whispering (Transmutation)

You summon a swarm of spirits and cause them to supernaturally animate nearby objects, bending them to your will. Choose up to six mundane objects within range that are not being worn or carried. All objects must be the same size, and you can animate six Tiny, four Small, three Medium, two Large, or one Huge object(s). Each object animates until the spell ends or until reduced to 0 hit points; when an animated object drops to 0 hit points, any remaining damage carries over to its original object form.

Command Objects Statistics

An animated object has 30 feet of blindsight and statistics as shown in the table above. The GM might rule an object has immunities, resistances, and vulnerabilities to specific damage types based on its form. If an object is securely attached to a surface or a larger object, such as a chain bolted to a wall, its speed is 0.
In combat, an object shares your initiative count, but take its turn immediately after yours.
As a bonus action, you can issue one command to any number of objects within the spell's range, otherwise, the only action an object takes on its turn is the Dodge action. An object may also be commanded to attempt an action available to all creatures, such as grapple or shove, if its form permits it to do so.
If commanded to attack, an object makes one melee attack against the target you specify within 5 feet of it. Its attack bonus is equal to your spell attack modifier. An object usually deals bludgeoning damage, but the GM might rule it inflicts slashing or piercing based on its form.
