True Vampire

Your vampiric transformation have reached its apex, making you akin to a true vampire. You gain the following features:

• Increase your Strength, Constitution, or Charisma score by 1, to a maximum of 20.
• Whenever you begin a turn in sunlight, you take 5 radiant damage. While in sunlight, you have disadvantage on ability checks and attack rolls. This radiant damage cannot be reduced or avoided in any way.
• You regain 5 hit points at the beginning of each of your turns, provided you aren't unconscious or in sunlight. If you take radiant damage, this trait doesn’t function at the beginning of your next turn.
