Ring of Fire and Ice

Ring Rare (this item requires attunement)

This glows with the same light that as if it has just come out of the forge.
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 source that would deal cold or fire damage.
In addition, the wearer gains a swim speed equal to half their movement speed and the ring sheds dim light for 10ft.

Cost: 600gp
