Mantle of the icy soul permanently adds the cold subtype to the targeted creature. The recipient of a mantle of the icy soul becomes immune to cold damage, but takes double damage from fire unless a saving throw for half damage is allowed, in which case it takes half damage on a success or double damage on a failure. The skin, hair, and scales of the creature subtly change color to take on an icy blue tint, and its breath does not frost in cold temperatures.

Material Component: A handful of ice or snow that must be pressed to the target's body.

XP Cost: 2,000.
