There seems to be little physical substance to this ring. It resembles a fine, circular sliver of fragile ice surrounded by a blue-white mist of incredible cold.

You gain resistance to cold 20, but you also gain vulnerability to fire and lose any resistance or immunity to fire you already have. You take 1-1/2 times the normal amount of damage from fire, regardless of whether a saving throw is allowed, or if the save is a success or a failure.

Prerequisites: Forge Ring, mantle of the icy soul (SC 138).
Cost to Create: 9,000 gp, 720 XP, 18 days.
