Boons:

• Blood of the Serpents: A creature that hits you with a melee attack that deals piercing or slashing damage and is within 5 feet of you takes acid damage equal to 1d4 + Your Dexterity Modifier.

 Flaw:

• Hideous Appearance: Your true form is hideous, whether due to your connection to curses or your tenuous ties to other realities.
  
  Although your appearance isn't necessarily scary, your form seems unnatural to normal creatures. Regardless of your true form, you are horrific to behold. You can suspend this form and manifest the appearance of the creature you once were, but this is taxing and requires concentration. This form is not permanent, and moments of stress are likely to reveal your true nature Your true form may be revealed in the following situations:
  • Becoming Bloodied
  • Concentrating on a spell
  • Gaining the Unconscious condition
  • Entering hallowed ground
  • Choosing to reveal yourself.
  In these events, or times of other extreme emotional or physical stress, a GM can call for a Constitution Saving Throw with a DC based on your current Transformation Stage:
  Stage 1: DC 10
  Stage 2: DC 13
  Stage 3: DC 16
  Stage 4: DC 20
