Elemental Empowered

You've discovered an innate connection to elemental forces, which you take advantage of in your spellcasting. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.  
• Choose acid, cold, fire, lightning, or thunder damage.
• When you roll damage for a spell you cast that deals your chosen type of damage, you can reroll any roll of 1 on the damage dice, but you must use the new roll, even if it is another 1.  
• Whenever you cast a spell that deals your chosen damage type, you can cause elemental force to wreathe you until the end of your next turn. The energy doesn’t harm you or your possessions, and they shed bright light out to 10 feet and dim light for an additional 10 feet. While the elemental shroud is present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 damage.  The damage type depends on the element you picked when selecting this feat.  
• When you cast a spell that deals damage of your chosen element, roll a d6, and you gain a bonus to one damage roll equal to the number rolled.
