• Increase your Dexterity or Charisma by 1, to a maximum of 20.
• You learn the ray of frost cantrip. The spell’s spellcasting ability is Intelligence, Wisdom, or Charisma when you cast it with this feat (choose when you gain the feat).
• You gain the ability to move across and climb icy surfaces without needing to make an ability check. Additionally, difficult terrain composed of ice or snow doesn’t cost you extra movement.
