Icy Embrace of the Spider

You learn to call on hellfire 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 cold damage for a spell you cast, you can reroll any roll of 1 on the cold 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 ice to wreathe you until the end of your next turn. Creating a chilling snow flurry within 5 feet of you makes the area difficult terrain to walk through. While the snow are present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 cold damage.
