Shadow Warped

"You can be honest with me. But first... be true to yourself. Do you not feel it? That gnawing, full-body, piercing ache of bitter disappointment. Day by day, time moves forward. And yet... you remain still. Repeating the same routine, simply going through the motions of life."
"Familiar. Predictable. Safe."
"A saccharine numbness lies over the happiness you struggle to obtain. It's alright. The illusion of greatness is nothing but a useless mirage. One that brings only pain. So let it go. Let all expectation fade away. Even if you do not achieve something extraordinary... you can still become someone who is true to who you are now." ~ The Brilliant Sun, The Beautiful Voice.

Your Inner Shadow becomes something with a constant impact on your day to day life, warping the way you see the world around you in some manner of distortive way.

When you have an amount of 'A Beautiful Voice' equal to or higher than twice your current level, at the end of each your turns the following effect attempts to occur.

• Distort. You must make a Charisma or Wisdom saving throw (your choice) with a DC of (8 + proficiency bonus + the ability score increased by this feat) or be suddenly overcome by your shadow. Your form warps in some manner that leaves you near unrecognizable, symbolic of the warped view in which you view the world. Once you have distorted, you are consumed by the negative emotions which have been so thoroughly heightened, more or less embodying those feelings and views. Many who undergo this transformation become violent, operating on feelings like rage or despair. You immediately gain your level in temporary hit points as this transformation occurs, may choose as part of this event to cast the spell granted by Shadow Touched, and your size increases by one category.

  Terminal: If you should ever have more stacks of 'A Beautiful Voice' than your level multiplied by half your proficiency bonus (rounded up), you must repeat this saving throw or immediately transform into a monster of the DM's choosing with a CR equal to or lower than your level. Should this occur, your character falls under the DM's control and is functionally dead. A creature that dies in this way can only be brought back to life by a Raise Dead spell or similar resurrection spell of greater level, where the creatures form then returns.
