Challenge  4 (1,100 XP) \n'b' SPECIAL TRAITS \n'b'\n'b'  Heat Drain . When the frost naga successfully constricts a foe, it absorbs their heat and heals itself for 1d4 points of damage. In addition, any fire- or heat-based attacks heal the naga instead of harming it: the ratio of healing is 1 point of healing per four points of damage. \n'b'  Heat Sense . The frost naga is able to sense and track normal human body heat sources at a range of up to 120 feet and fire up to one mile. This also grants the naga blindsight so long as there are heat variances in the area. \n'b'  Freeze surroundings . The area (20 feet) around the frost naga is always frigid and drops to about 25 degrees F. The ground and walls freeze instantly creating a slippery surface which is  difficult terrain . A  Dexterity  save (DC 15) allows normal movement, though failure means the target falls  prone , requiring an action and a second  Dexterity  save (DC 15) to stand again on the slippery surface. Anyone not prepared for the sudden drop in temperature also suffers 1-4 points of temporary cold damage, which heals at 1 point per hour after leaving the area. \n'b'  Silent Call . A frost naga can emit a silent (mental) call for help when it is attacked. Any other nagas within 250 feet can sense this and come to its aid. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The naga attacks twice, with its bite and its tail. \n'b'  Bite .  Melee Weapon Attack : +5 to hit, reach 10 ft., one creature.  Hit : 10 (2d6+2) piercing damage. \n'b'  Tail .  Melee Weapon Attack : +5 to hit, reach 10 ft., one creature.  Hit : 12 (2d8+2) bludgeoning damage, plus constriction. \n'b'  Constrict .  Melee Weapon Attack : On successful tail attack, the target is  grappled  and  restrained , suffering 2d8 points of damage at the beginning of each of the  naga \xe2\x80\x99s turns and  healing  the  naga  for 1d4 damage. The escape DC is 13. \n'b'\n'b' ABOUT \n'b' The frost naga is a bizarre creature originating from the nether planes. They have long slender snake-like bodies of silvery or bluish-white hue. A thin, black, razor-sharp spike tops the tail. The body is topped by a hideous female human head with silvery, matted hair and long fangs. They emit a pungent odor, not necessarily unpleasant, that smells of burnt coal. \n'b'  Guardians of Gateways . As with most nagas, frost nagas serve as guardians. Unlike most other nagas, these nagas primarily guard doorways and entries because of their unique ability to call upon other nagas in the vicinity to help them. \n'b'  Heat-Seekers . In combat, the frost naga tries to move in and constrict an opponent while biting them in order to steal their heat and heal itself. While doing so, the frost naga uses its tail to attack others or keep them at bay.'
