Your Yeti blood begins to surface and you are imbued with some of a Yeti's elemental ice power. You gain a +1 to Strength, Constitution, or Wisdom and gain resistance to cold damage. In addition, When you take the attack action on your turn, you can replace a single attack with a howl that flash freezes the air around you. Each creature of your choice in a 15-foot-radius sphere centered on you must make a Dexterity saving throw (DC equals 8 + your proficiency bonus + the modifier of the ability increased by this feat). On a failed save, a creature takes cold damage equal to 1d8 + your proficiency bonus, and it has the blinded condition until the start of your next turn, as your howl forms hoarfrost on the bodies of your targets. On a successful save, the creature takes half as much damage only. You can use your hoarfrost howl a number of times equal to your proficiency bonus (but no more than once per turn), and you regain all expended uses when you finish a long rest.
