Cloak of Squirrels Wondrous item, rare (requires attunement) This wool brocade cloak features a repeating pattern of squirrel heads and tree branches. It has 3 charges and regains all expended charges daily at dawn. While wearing this cloak, you can use an action to expend 1 charge to cast the legion of rabid squirrels spell (see Deep Magic for 5th Edition) from it. You don’t need to be in a forest to cast the spell from this cloak, as the squirrels come from within the cloak. When the spell ends, the swarm vanishes back inside the cloak.

LEGION OF RABID SQUIRRELS
3rd-level conjuration
Casting Time: 1 action
Range: 60 feet
Components: V, S, M (an acorn or nut)
Duration: Concentration, up to 1 minute

While in a forest, you call a legion of rabid squirrels to descend from the nearby trees at a point you can see within range. The squirrels form into a swarm that uses the statistics of a swarm of poisonous snakes, except it has a climbing speed of 30 feet rather than a swimming speed. The legion of squirrels is friendly to you and your companions. Roll initiative for the legion, which has its own turns. The legion of squirrels obeys your verbal commands (no action required by you). If you don’t issue any commands to the legion, it defends itself from hostile creatures but otherwise takes no actions. If you command it to move farther than 60 feet from you, the spell ends and the legion disperses back into the forest. A canid, such as a dog, wolf, fox, or worg, has disadvantage on attack rolls against targets other than the legion of rabid squirrels while the swarm is within 60 feet of the creature. When the spell ends, the squirrels disperse back into the forest.
