Monkey Ring

Once attuned to, the wearer can spend 1 hour to
summon a familiar. The familiar always takes the
form of a capuchin monkey (stat block provided),
although it is technically a fiend. The ring can
only be used to summon a new familiar once the
current has died (0 HP). For all other purposes,
the familiar has the same abilities and limitations
as imposed by the Find Familiar spell.
