Ring Rare (this item requires attunement)
This oriculum ring has an unusual type of patina that gives it two colours: Green and Blue.
This ring has three charges and all charges are regained at dawn. While the wearer is attuned to the ring, the wearer can use their reaction and expend a charge in order to half the damage to the wearer from any spell that could be found on the Druid or Ranger spell list or a source that deals cold damage.
In addition, the wearer gains a swim speed equal to half their movement speed and the wearer cannot be slowed by any plant life that would impose difficult terrain.
Cost: 500gp
