Belt of the Monkey

While attuned to this belt you add double your
proficiency to Athletics or Acrobatics checks to
climb. As an action, you grow a 3-foot prehensile
tail out of your posterior for an hour. You can
hang from your tail, provided it has something
to hold onto. Your tail also acts as a third arm
and hand, allowing you to manipulate and wield
objects that weigh 5lbs. or less. You cannot use
this ability again until you have completed a
long rest.
