By taking this Essence, you gain vast power over your own shape, and can alter it at will.
*You may set your 'default' or 'true' form to any form that you can shapeshift into as long as you seriously consider it as such, meaning that you will never have to revert to what you were before.
*You may physically and metaphysically and conceptually transform into anything (including inorganic forms) not vastly larger or more massive than you or a result of metaphysical growth that you have not undergone. (i.e. you could transform into a kitsune, but you can't transform into a nine-tailed version without going through the spiritual growth required of a normal kitsune). However, you find that your limits are less harsh when copying something that you have personal seen or when you are working with an established form.
*You may also use your abilty to shapeshift as a makeshift regeneration power, though it is often ineffective against cursed weapons.
*You may also emulate biological powers that you have encountered (such as mutant powers from Marvel), but often get them in an undeveloped form that requires hard work to grow. (i.e. If you tried to transform into a Kryptonian, you would likely only gain golden age kryptonian powers on the level of 'fast as a speeding locomotive' without further development such as research, extensive specialized training or solar exposure in that form)
*You gain a perfect memory of what your form was at any time during your life, and may revert to any prior state at will.
*The more time you spend in a form, the more you subconsciously alter it to better fit your desires. A 'standard' human form that you stay in for a few days might become peak human, while with weeks it might gain a wide variety of low-end physically possible superpowers, such as the senses of the best of the animal kingdom, the ability to conduct photosynthesis and a functionally perfect memory.
*You gain an instinctive understanding of mundane biology that lets you customize your form with a wide variety of biological equipment, such as allowing you to echolocate, perceive the infrared spectrum and magnetic fields.
*You may toggle immunity to any body dysphoria that any of your forms grant you, letting you comfortably change into any shape.
*Any children that you bring to term has an optimal blend of all of the biological abilities that you have mastered as well as that of your partner, and you find that shifting is no bar to maturing your babies to term. This applies to a lesser extent to any children that you father as well.
