This magical cloak of mottled brown, gray, and green resembles the murky depths of rat-infested sewers. It has 6 charges for the following properties. It regains 4 expended charges daily at dawn. When it is worn by a creature attuned to it and it has 1 or more charges, shadows in the shape of rats scurry back and forth across the backside of the cloak. The more charges it has, the more rats can be seen.

Vermin Minion. While you wear the cloak, you can use an action to expend 1 charge to cast either the animal messenger spell or the find familiar spell. If you cast animal messenger, the cloak conjures a rat from within its folds, which the spell must target. If you cast find familiar, you can't cast spells through the familiar, and the familiar is a rat.

Swarm Cloak. While you wear the cloak, you can use a bonus action to expend 2 or more charges to surround yourself in a protective swarm of bats. Roll 3d10; the swarm has that many hit points, plus 5 additional hit points for each charge expended. For 1 minute or until the swarm is reduced to 0 hit points, you gain a special 30 foot climbing speed which does not provoke opportunity attacks, and you deal 1d10 + 5 piercing damage to each creature of your choice within 5 feet of you at the start of each of your turns. If you would take damage, the swarm blocks that damage and takes the damage instead. The swarm cannot block psychic or poison damage unless it is dealt by an attack. If the swarm is reduced to 0 hit points by damage, you take any damage that remains.
