Essence of Endless Lives
By consuming the Essence of Endless Lives, the primal urge to experience life in all of its infinite variety, you ensure that your soul will have as many chances to experience life as you wish.
* Your soul is unbound from the normal cycle of existence and becomes absolutely indestructible, untrappable, and unownable. Nothing short of the Supreme Being can prevent you from being reborn.
* Every time your life ends, by any cause up to and including total conceptual retroactive destruction of your existence, you will reincarnate into any universe you wish and at a location and time of your choosing. With one exception, every time you are reborn will be into a separate timeline.
* The exception is that you may choose to 'rewind' the same life you just died in, all the way back to the beginning. You may rewind more than once. You rewind all the way back to birth every time you choose to rewind at all. You do not have to rewind any life unless you want to, but after you have moved on to a new life you may not go back and rewind a prior life yet again.
* As part of your being unbound from the normal cycle of existence you may choose the parents you are born to and the circumstances you are born into, each as privileged or as poor as you want them to be. However, from birth onward your karma will be neutral and without any predestined fate or destiny.
* You may reincarnate into a newborn of any sentient race that exists in-setting, and will for the duration of that lifetime have all the powers and abilities that your new body would normally have. You may reincarnate into any entity below the 'cosmic being' tier of power.
* You may, if you wish, have your memories and abilities lie 'dormant' until you are out of infancy and into childhood.
* You may choose to reincarnate into a 'special' example of your new race, one born with or destined to obtain powers or abilities not common among its species, but only so long as such entities would already exist in-setting to potentially reincarnate to. (For example, you could not reincarnate into a baby with mutant superpowers unless superpowered mutants were already a thing in that world.)
* You may freely reset your physical stats with every new life, within the racial minimums and maximums of the new life you are reincarnating into. Your mental stats will remain your own but you will carry forward any improvements in those stats between lives. You will never have 'dump stats' unless you choose to, and 'dump stats' will always reset to normal after you end a life.
* With each new life you will have the opportunity to 'leave behind' any emotional or mental trauma that occurred in previous lives and start afresh, if you choose to.
* You gain perfect memory with infinite storage. You always have perfect awareness of which memory occurred in which lifetime.
* You are always naturally adapted to whatever new form you reincarnate to however weird or non-humanoid it may be. Any species you are born into will be experienced as if you had always been that species. In later lives the memories of these more exotic existences will remain comprehensible, if possibly somewhat detached from your current existence.
* Barring another ability or Essence that would allow them to, powers and abilities do not transfer between lives unless they would be an artifact of the soul or the mind and not the body. Likewise, powers and abilities only transfer between lives if the metaphysics of the universe you are reincarnating into would support their existing there.
* As a specific exception to the above, note that "muscle memory" is actually part of the mind and so mundane skills and knowledge - even physical skills - always carries over. Your perfect memory will keep you from suffering from inconvenient reflexes or habits that may be associated with a body shape that you no longer have.
* You may end your endless cycle of lives and move on to what comes next, but only if you while entirely in your right mind and with the utmost sincerity want to.
Essence of the Stronghold
You get your own fortified Stronghold, which exists outside the bounds of time, space, and even reality. This renders it beyond the reach of most anyone, and even those that do reach it will find that it's protected by an impenetrable field. Only those that you allow will be able to enter.
Any currency you gain is automatically sent to a vault inside the Stronghold, and you can call it back any time you wish. The vault will grow larger as you collect more money, so you'll never run out of room to store your money. Different currencies go into different vaults, to keep things nice and orderly. Any weapons and armor you gain are stored in an armory, and organized neatly.
You can "switch" weapons and armor in and out at will, with clothes going to their own place. You gain a table with a terrain map of the last region you were in before entering the Stronghold. It shows any major cities, landmarks, and points of interest. It also shows any real estate you have in those locations.
It also shows the locations of any mission you have. You get a wardrobe room, where any clothes, beards, hairstyles, makeup, and tattoos you've had are stored, and where you can wear them again. No, it doesn't make sense for some of those things, but this is an extrauniversal living space, which is debatably more odd.
Any furniture you buy/steal/otherwise gain are stored in a basement storage area, and can be applied to any room in the Stronghold. While in this stronghold, all aging is halted, will not have any basic needs, and no longer grow ill.
You can change the default aesthetic of the stronghold, which is a posh medieval castle, to any other theme you wish.
The Stronghold, being the extraversal place it is, can take you anywhere in the multiverse. It can insert itself into these places, or open a literal doorway there. If you wish, the Stronghold may become sapient, and can generate servants to handle various tasks, such as cleaning, cooking, and other miscellaneous things.
The Stronghold is unwaveringly loyal to you, and nothing can influence it otherwise. The Stronghold can also generate an avatar of its own, or take over the body of one of the servants.
Essence of the Revenant
By drinking this essence you will receive a number of boons.
You have become an undying monster that exists only to kill. You no longer age, nor do you need to eat, drink or sleep.
You are utterly indefatigable and can keep moving forever. You are strong enough to toss cars, tear steel like putty and reduce the heads of men to pulp with a good stomp or squeeze.
You are faster than cars in a dead sprint and can move quick enough to resemble teleportation at a dead sprint.
You can also swim effortlessly and at great speed. Your durability is incredible, allowing you to survive absolutely monstrous amounts of damage and trauma, while your reaction to pain is non-existent.
Your head needs to be destroyed or your body reduced to a chunky paste for you to actually die, which would likely require explosives or incredibly large amounts of high-caliber bullets to die.
What damage that doesn't kill you will rapidly regenerate, healing minor damage in seconds and vanishing brutal wounds in minutes.
But death is not the end for you. Your existence is imperishable and nothing can keep you down forever, allowing you to recover from any level of damage and resurrect after your death.
You can choose how long it takes you to recover from a minimum of three days up to a year or longer.
Your senses are sharpened to a point more animal than man, allowing you to track your prey through adverse conditions and hear their terrified hearts in their hiding places.
While you have no true combat skill from this, you do have absolutely lethal instincts and brutal ferocity on your side.
You can instinctively find weaknesses in your prey and know exactly how to use anything you come across to exploit those weaknesses to lethal effect. A martial artist might be more skilled in combat than you, but if you get your hands around his throat then his death is guaranteed.
Indeed, your violent and murderous nature grants your attacks a sort of all-killing potency. Your strikes seem to pierce through supernatural powers and defences, leave behind wounds that simply refuse to heal without great effort and those that you kill will stay dead.
The murderous will that suffuses your attacks also protects you, making your mind a fortress that cannot be accessed or altered while making it orders of magnitude more difficult to affect you with supernatural abilities ranging from telekinesis to stranger esoteric powers.
You are incredibly talented at stealth and stalking your prey without their notice, ghosting them from a distance or even from right behind them.
You can slip through defences and observations easily, avoid notice effortlessly and even the effects of your actions seem to go without notice as if by magic when you want them to.
Your target's screams can be oddly muffled, the sound of you smashing through a window won't travel and even your powerful footsteps can be silent when you wish.
At will you may deaden your heart, suppressing things like empathy, compassion, guilt and other emotions that would stay your hand.
You may choose to what degree this takes effect and may deactivate it whenever you would wish it to do so.
You can choose to have a mask and weapon of your choice. These two items can look however you wish, from a hockey mask and machete to a white latex face and a butcher knife, and will be indestructible and always at hand when you reach for them.
