Jsk Wondrous Items:Hat of Bears

Source: Jnome's Secret Knowledge

Hat of Bears Weapon (Any), Uncommon (Requires Attunement)

While holding the hat, you can use an action and speak a command word that summons a black bear (see the Player's Handbook or the Monster Manual for statistics). The summoned creature magically appears within 5 feet of the hat. The creature is friendly to you unless you give it a reason not to be. It isn't under your control, but while friendly it may perform tasks for you or fight for you. It behaves as an ordinary creature of its kind and disappears after 1 hour or when it drops to 0 hit points. The hat can be used once per day, and regains its use at dawn.
