Animate Object

An object comes to life at your command. Choose a Tiny or Small nonmagical object within range that is not being worn or carried. The target animates and becomes a creature until the spell ends or until reduced to 0 hit points.

The creature is not under your control.

Animated Object Statistics

An animated object is a construct with AC, hit points, attacks, Strength, and Dexterity determined by its size. Its Constitution is 10 and its Intelligence and Wisdom are 3, and its Charisma is 1. Its speed is 30 feet; if the object lacks legs or other appendages it can use for locomotion, it instead has a flying speed of 30 feet and can hover. If the object is securely attached to a surface or a larger object, such as a chain bolted to a wall, its speed is 0. It has blindsight with a radius of 30 feet and is blind beyond that distance. When the animated object drops to 0 hit points, it reverts to its original object form, and any remaining damage carries over to its original object form. 

It can make a single melee attack against a creature within 5 feet of it. It makes a slam attack with an attack bonus and bludgeoning damage determined by its size. The GM might rule that a specific object inflicts slashing or piercing damage based on its form.
