Ring of coolth

A ring of coolth protects the wearer from hot environments. While wearing the ring, the wearer is considered to be fully protected against all hot temperature bands up to extreme heat, and partially protected against unearthly heat (181–210 °F) or burning heat (211 °F or higher). He gets a +5 bonus to saving throws against the effects of hot environments.

A ring of coolth also protects the wearer from fire-based attacks, reducing the damage taken from such attacks by up to 10 points per round. (This does not apply to damage caused by environmental conditions.)
