This is a magical item not usually found in treasure hordes, and its
application is somewhat limited. Nonetheless, it can be of some use to
adventurers. A Ring of Oak  is a simple, flexible band of wood which,
when taken from the home tree of a dryad and worn on the finger, allows the dryad to move out of the vicinity of her tree and roam as an
adventurer. Few (if any) true dryads have the wanderlust, but some
player characters may find themselves reincarnated, through the
druidic spell of the same name, as a dryad, and may wish to continue
adventuring


A small, green twig is taken from the dryad’s tree and is woven into
a ring shape. Then an Astral Spell  and a Wish  must be cast on the
ring, and it is thereby attached by a silver cord through the astral plane
to the home tree; the cord has a 1% chance per month of breaking
through any outside influence. The dryad will not voluntarily remove
the ring when more than 36” away from the home tree. If the ring is
lost or the cord breaks, the dryad loses one point of Strength per day
until the ring is returned or she finds her way back to within 36” of her
oak tree. If her Strength reaches zero, she will die; she will undergo a
similar loss of Strength if her home tree is destroyed while she is
absent, unless a Wish  is used to “resurrect” the tree. Strength is recovered at one point per day if death is avoided by the recovery of the
Ring  of Oak  or a return to within 36” of the tree.
