The kamaitachi can enter a hostile creature\xe2\x80\x99s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing. \n'b'  Concealing Snow (True Form Only) . As a bonus action, the kamaitachi sheathes itself in blowing ice and snow, causing  attack  rolls against it to have disadvantage. The kamaitachi can use this trait only if it is in snowy terrain. \n'b'  Flyby (Wintry Swirl Form Only) . The kamaitachi doesn\xe2\x80\x99t provoke opportunity attacks when it flies out of an enemy\xe2\x80\x99s reach. \n'b'  Keen Smell . The kamaitachi has advantage on  Wisdom  ( Perception ) checks that rely on smell. \n'b'  Shapechanger . The kamaitachi can use its action to  polymorph  into a swirl of wintry weather. It can revert back to its true form as a bonus action. Its statistics are the same in each form. Any equipment it is wearing or carrying isn\xe2\x80\x99t transformed. It reverts to its true form when it dies. While a wintry swirl, it has a flying speed of 40 feet, immunity to the  grappled ,  petrified ,  prone , and  restrained  conditions, and  resistance  to bludgeoning, piercing, and slashing damage from nonmagical attacks. \n'b'  Snow  Devil  (Wintry Swirl Form Only) . Until it attacks or uses Wintry Assault, the kamaitachi is indistinguishable from a natural swirl of snow unless a creature succeeds on a DC 15  Intelligence  ( Investigation ) check. \n'b'  Actions \n'b'   Multiattack . The kamaitachi makes two sickle paw attacks. \n'b'  Sickle Paw (True Form Only) .  Melee Weapon Attack : +6 to hit, reach 5 ft., one creature.  Hit : 18 (4d6 + 4) slashing damage. \n'b'  Wintry Assault (Wintry Swirl Form Only) . Each creature in the kamaitachi\xe2\x80\x99s space must make a DC 15  Dexterity  saving throw. On a failure, the creature takes 9 (2d8) slashing damage plus 9 (2d8) cold damage and is  blinded  until the end of its next turn. On a success, it takes half the damage and isn\xe2\x80\x99t  blinded . \n'b'  About \n'b' Despite having bony sickles for paws, this large weasel moves adroitly as snow and ice whip around it. \n'b'  Related to Wind Weasels . Kamaitachis derive from a family group of wind weasels that migrated and acclimated to far northern forests. As a result, they lost their connection to the fey, shrinking and devolving into more natural beasts. Their claws fused to become one large, sickle-like claw on each paw. They retain the wind weasels\xe2\x80\x99 jealousy of humanoids and aggressively attack intruders. \n'b'  Stinging Winds . Like their fey cousins, the kamaitachis can turn into a swirl of wind, but they incorporate ice and snow instead of leaves, chilling their victims. Even in their weasel forms, they surround themselves with wintry precipitation that obscures them from sight. \n'b'  Summer Migrations . Kamaitachis thrive for most of the year in arctic forests. Prior to summer, they migrate closer to the pole to stay in contact with frozen water, most of which disappears in their forests during the warmer weeks. Once snows begin to fall again, they return to their forests and relentlessly drive out creatures that moved in during their absence.'
