Mark of Serendor

You are marked by the ancestry of house Serendor and can call on that power 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.
• Each time you cast a spell that deals cold damage, you cause ice crystals to fall within 10 feet of you until the end of your next turn. The crystals do not harm you or your belongings, and they cast bright light at 15 feet and dim light for another 15 feet. While the crystals are present, any creature within five feet that hits you with a melee attack takes 1d4 cold damage.
