A shasalqu exudes a heat-sapping aura. Any creature that begins its turn within 10 feet of a shasalqu takes 1d6 points of cold damage and becomes entangled. A successful save negates both effects. An affected creature is entangled for as long as remains within the aura's area plus 1 additional round. Creatures whose cold immunity or resistance prevents all cold damage are not entangled. When a shasalqu dies, this aura persists around its corpse for 1 hour. The save DC is Constitution-based.
