Shards of Soulfreeze

You learn to call on the blizzards that consume Soulfreeze, the land of Aseroth (566th Layer of Hell) the  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 icy winds to wreathe you until the end of your next turn. The frost don’t harm you or your possessions, and they shed bright light out to 30 feet and dim light for an additional 30 feet as the ice reflects the light given off by your magic, amplifying it beyond normal means. While the icy winds are present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 cold damage.
