This spell maintains a creature's body heat against cold for 4 hours, plus 1 additional hour per level of the caster. Also, any cold-based damage is restored at the rate of one hit point per turn. When exposed to magical cold or special cold-based attack, the protected creature receives a +2 bonus to saving throws, and cold-based damage is reduced by 1 point per die. This spell is not cumulative with any other magical protections against cold.
Notes: Very rare druid spell. (Updated from Dragon Magazine.)
