Ring of Anti-Venom:
This item appears to be
ornately carved from the horn or tooth of
some enchanted creature. It gives the wearer
full protection from poison. Any time a SAVE vs. poison
is required, a charge is automatically
expended from the ring, and the
SAVE succeeds. The ring has 20 charges
at most, and crumbles into dust when the last
is used. Before then, the ring can be recharged
by a <priest> of 12th or higher level.
    XP: 2000*
    GP: 10,000*
    * Assumes full charges; deduct proportionately.
