Blue touch covers one of the caster’s hands with a blue aura, which is transferred by touch to a creature or object. The aura draws heat and burns out of the thing touched, healing 1d4 hp +1 point per level of the caster (maximum 1d4+5). The healing only works on hp lost to fire damage, or on any damage suffered by a creature of the [cold] subtype. A target of this spell stops bleeding (stabilizing if dying) even if it has suffered no fire damage.
