Animate Pest

You reanimate the corpse of a dead rodent or insect, such as a rat or a cockroach, or similarly diminutive beast. The reanimated creature is undead and uses the rat template for its statistics. It acts on your turn, can climb any solid surface, and can move into another creature's space, but it cannot fly, swim, or borrow. The creature moves silently and has advantage on Dexterity (Stealth) checks, using your spell ability modifier for the roll. Negative energy constantly leaches from its rapidly deteriorating body, revealing its undead nature to any creature that sees it. When the spell ends or the creature is destroyed, it falls apart and dissolves into a fine dust, consumed by the negative energy used to create it.

While the spell is active, you may use bonus actions to whisper commands to the reanimated creature. The creature can hear your whispers up to 60 feet away and will follow the command to the best of its ability, but it is only able to take the dash, disengage, dodge, and hide actions, and it cannot use or manipulate items.

Additionally, you can use a bonus action to command the reanimated pest to distract another creature by crawling onto it. Assuming the pest can reach the target, the target must make a Dexterity saving throw. On a failed save, the next attack against the target has advantage until the end of your next turn.

You are unable to issue commands to the reanimated creature if either of you are subject to an area of magical silence. If the creature is not given or is unable to receive a command, it remains stationary and takes the dodge action.
