A creature that touches the shimmer snake or hits it with a  melee attack  while within 5 feet of it takes 3 (1d6) fire damage. \n'b'\n'b' Actions \n'b'\n'b'  Bite .  Melee Weapon Attack : +6 to hit, reach 5 ft., one target(s).  Hit : 7 (1d8 + 4) piercing damage and 3 (1d6) fire damage. If the target is a Medium or smaller creature, it must succeed on a DC 14  Dexterity  saving throw or be swallowed by the snake. A swallowed creature is  blinded  and  restrained , it has total  cover  from attacks and other effects outside the snake, and it takes 3 (1d6) fire damage at the start of each of its turns. If the snake takes 20 damage or more on a single turn from a creature inside it, the snake must succeed on a DC 17  Constitution  saving throw at the end of that turn or regurgitate any swallowed creatures, which fall  prone  in a space within 5 feet of the snake. If the snake dies, a swallowed creature is no longer  restrained  by it and can escape from the corpse by using 20 feet of movement, exiting  prone . \n'b'  Surface Strike (Recharge 5-6) . A burrowing shimmer snake, no deeper than 5 feet from the surface, can superheat the ice around it, forcing scalding water to erupt upward from the surface in a 5-foot column. Any creature within the column must make a DC 14  Constitution  saving throw, taking 9 (2d8) fire damage on a failed save, or half as much damage on a success. Each creature within 5 feet of the column must succeed on a DC 14  Dexterity  saving throw or take 2 (1d4) fire damage. \n'b'\n'b' About \n'b' A thick-bodied snake, the shimmer serpent is covered in lush fur from the tip of its tail to the base of its head.\xc2\xa0Two pairs of vestigial legs adorn its length, which is easily twice the height of any human. \n'b' The shimmer snake gets its name from the pleasant yellow-green glow it creates while burrowing beneath the icy surface. Such displays have lured many a lost traveler seeking the safety of a campfire into a nest of shimmer snakes (and ultimately their bellies).'
