Ring of Many Forms

While wearing this ring, you can expend a charge as an action and cast alter self.  The spell save DC is 15.  The ring has 5 charges and regains 1 charge each day at dawn.

If attuned by a character with at least 2 levels in the Druid class, the ring enhances the Druid's wild shape class feature as follows:  the ring permits an additional wild shape per day, increases the CR of the wild shape by 1, and extends the time the Druid can remain in wild shape by 1 hour.
