Rime of Cania

You learn to call on hellfrost to serve your commands. You gain the following benefits:

• Increase your Intelligence or Charisma score by 1, to a maximum of 20.
• When you roll ice damage for a spell you cast, you can reroll any roll of 1 on the ice damage dice, but you must use the new roll, even if it is another 1.
• Whenever you cast a spell that deals cold damage, you can cause icy winds to whip around you until the end of your next turn. The cold doesn’t harm you, and ethereal frost rimes any creature within 30 ft of you, revealing any invisible creatures or objects. While the winds are present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 cold damage.
