Essence of the Involate Self
Drinking this essence confers you the blessing of inviolability of the body, mind, and soul:
You now no longer need to eat, drink, breathe, produce human waste, or sleep, and are immune to the harmful effects of radiation alongside extreme environments ranging from the bottom of the ocean to the vacuum of space.
Total immunity to all forms of poison, sickness, or disease, mundane or otherwise. Any existing ailments of physical, mental, or spiritual nature that plagues you will be completely cured upon drinking this essence.
You are biologically immortal and utterly tireless, possessing unlimited stamina - you will be aged/reverted to your physical prime, but no longer age further.
Infinite willpower to keep going through any amount of hardship; even bloody and broken you will not stop, and you will forevermore be protected from the effects of despair, boredom, ennui, etc., that will make living forever a pain in the ass.
Your freedom is also inviolate, protecting you from being imprisoned, incapacitated, trapped, bound, sealed, etc. against your will, automatically freeing you from such situations and teleporting you to the nearest safe location.
You are completely immune to any attempt to forcefully change, control, or manipulate your body, mind, and soul against your will in any fashion no matter what method is attempted or used.
Those that use supernaturally boosted persuasion are equally stymied, being forced to rely on simple mundane arguments against you as anything beyond that flatly fails to work. You are also immune to memetic effects or the maddening effects of eldritch beings or phenomena.
Your soul cannot be targeted as a vector of attack - the only thing you are still vulnerable to will be actual physical violence, if such things can cause damage to you.
No Oracles or any other form of precognition can account for you, ever. Any predictions that are made will be made without taking you in account, and if seeking you out directly, all they get is static. In addition, you are not bound by fate anymore; your destiny is only what you make of it. This extends to the point that people and events that are deemed unstoppable or even unkillable, just because they are destined to, can be killed by you permanently.
You are also immune to reality warping shenanigans, such as being caught in time paradoxes, time stops, not existing due to someone killing your mother when she's pregnant with you, etc. - your very existence is inviolate.
Note: You can still be injured or killed through direct physical damage, if such things are capable of damaging you; all this Essence does is preventing your body, mind, and soul from being affected by other forces without your consent.
Essence of Eternity
By consuming this Essence you embrace living a truly eternal existence.
* At the time you drink this Essence you will be cured of any and all physical ailments, pre-existing conditions, psychological trauma, and other unwanted mental conditions, ailments, disabilities, etc. Your body will be reset to be strong, healthy, and athletic with zero genetic defects or pre-existing conditions. Your age will also be reset to the prime of life, unless you were already younger.
* You will cease aging once you reach the prime of life, and you will live forever. Your health and fitness will always be maintained as if you were practicing clean and healthy living and receiving comprehensive modern medical care throughout, even if you are not. You will always eventually recover 100% and without impairment from any injury, even if you normally would not.
* Your mind and soul are also fully adapted to an eternal existence. Your memory will be able to index and process any number of eons of stored experiences as easily as it already could have done so for your original mortal lifetime. You are wholly immune to any ennui, boredom, despair, etc., that might be caused by your extended lifespan. You will remain as able to relate to and empathize with those around you as much as you always could, and in general will not be changed, embittered, or otherwise subjected to unwanted value drift by your eternal existence… except possibly for the better.
* You have impenetrable plot armor versus death, death of personality, psychological destruction, and other really bad things. Narrative causality will always twist just enough to ensure that nothing can permanently remove you from the action economy against your will. Even things like banishment to a nether-realm, entombment, etc., will eventually fail and let you find a way out. Even if the very planet you live on should be destroyed or the universe itself eventually succumb to final entropy, you will have opportunities to escape to another place beforehand.
* Optional: You may share this Essence with those you truly, deeply, and intimately care for. No cheesing, the ineffable powers behind the Essence Meta will know if you really mean it or not. You may not do take-backs once you have shared it, so be careful who you choose.
* When you are finally ready to stop living and move on to what comes next, you will. This will only happen if you wish to do so while entirely in your right mind and with the utmost sincerity.
