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 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.
