Warm self

You warm yourself up, not necessarily raising your body temperature, but simply emitting a warm aura around you in a 5 foot radius. You can choose the temperature, from a minimum of 75 degrees F to 90 degrees F. This spell  can be used to negate effects of natural cold and to slowly melt weak ice. The only requirement for this spell is the action of rubbing the caster's hands together for a short period.
