Essence of the Shape
By taking this essence, your form has become a suggestion, rather than something rigidly defined.
*You no longer have a default form. Everything about you can be changed by your whim.
*You can shapeshift into forms that have greater or less mass than you, including inanimate objects.
*You can split off pieces of yourself and shapeshift those.
*You can transform into any being and gain their powers, along with combine multiple beings.
*You may transmute any matter, energy or living being around you into anything.
