Bloodright Manifest

You've learned how to project the vampiric power in your blood into a potent aura. You gain the following benefits:

• Increase your Wisdom or Charisma by 1, to a maximum of 20.
• When you roll necrotic damage for a spell you cast, you can reroll any roll of 1 on the necrotic damage dice, but you must use the new roll, even if it is another 1.
• Whenever you cast a spell that deals necrotic damage, you can cause ethereal bats covered in shadow and smog to wreathe you until the end of your next turn. These bat-like apparitions don't harm you or your possessions. Additionally, they smother light within 30 feet of you causing it to become nonmagical darkness, with light 30 feet further becoming nonmagical dim light. While the bats are present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 cold damage.
