Bell of Pspspsp

Wondrous item, rare (requires attunement)

This golden bell has 9 charges and regains 1d6 + 3 expended charges daily at dawn. You can use a bonus action to ring the bell and expend 1 of its charges. When you do, the bell emits a soft, tinkling chime, and a swarm of cats magically appears in your space: treat the swarm as if it were a swarm of rats, but it has AC 12 and a +2 bonus to saving throws. You can verbally command the swarm on each of your turns (no action required), which takes its turn immediately after you. The swarm remains for 1 minute or until it's reduced to 0 hit points, at which point the cats disappear in a small cloud of fur. For the duration, you can use a bonus action to ring the bell again, without expending any charges, to cause the swarm to magically return to your space (provided it's on the same plane of existence as you) and regain 2d6 hit points; its Swarm trait doesn't prevent it from regaining hit points in this way.

A Medium or smaller creature (other than you) that starts its turn in the same space as the swarm of cats must succeed on a DC 15 Dexterity saving throw or be knocked prone. If a creature falls prone in this way, the swarm can immediately use its reaction to make a bite attack against the target.

Alternatively, while holding the bell, you can use an action to expend 1 of the bell's charges to cast the speak with animals spell from it. This version of the spell only allows you to communicate with cats or similarly feline creatures, even if they aren't a beast (such as a lion, griffon, or chimera). The spell ends early if the bell is no longer on your person. You gain a +5 bonus to any Wisdom (Animal Handling) or Charisma check you make to interact with such creatures for the duration of the spell.

If you expend the last charge from the bell, roll a d20. On a 1, the bell ceases to make any noise when it's rung and loses its magic.
