Essence of the Doom Slayer
You have received and survived the same Divine Enhancement the Doom Slayer received, granting you immense superhuman physical capabilities, an eternal lifespan, the ability to survive without the need for any sustenance and complete immunity to any form of corruption. All of the Doom Slayer's enhancements are now yours, even those not mentioned here.
Optionally, you may receive the power that made the Doom Slayer more dangerous over time. For like the Doom Slayer, you now become more powerful with every being you slay, absorbing a part of their. This can be anything from some of their strength to a unique ability they have, but will most often be a physical enhancement, like increase in strength or health. The stronger the being you kill is, the more power you receive from them, but even from the weakest being you will receive something. It might be a negligible increase, so tiny you might not even notice, but it will still be there.
Optionally, you may receive the power of the Deag Priests, allowing you to designate a champion. As long as that champion is alive, you cannot be killed nor hurt. You make someone a champion by giving them a Blue Medallion you create at will, which will merge with the champion. Should the champion die, then the Blue Medallion will be released by the Champion and make you vulnerable again. You can then give the Medallion to another champion, but you have to retrieve the Medallion from the corpse of your former champion.
Like the Doom Slayer, you have received training from the Night Sentinels, making you a true monster in combat, having mastered nearly every form of weapon and hand to hand combat. This is the training that turned the Doom Slayer into the efficient combat machine he became.
This has also taught you the ways of Glory Kills, brutal things which cause fear to develop in your enemies.
Thanks to your Night Sentinel training, you have become non-squeamish. Even when blood flows like water, flesh and corpses pile up like mountains and the screams of the damned are nearly around every corner, you will find yourself completely unbothered by scenes of intense gore and violence.
Optionally, You may choose to have infinite willpower, allowing you to fight in hell for eons and not break. You will also find that your mind will not suffer from loneliness.
You become capable of traversing freely between dimensions in order to hunt those who would make humanity and all other sentient life their prey, with your powers bringing you to where you are most needed at the moment.
You produce an aura that makes creatures of the dark instinctively fear you, although if they happen to be morally aligned with good, this aura does not affect them. Additionally, this aura can also be used to ward off evil influences in others, freeing them from the darkness's embrace.
You have the ability to carry any amount of weapons, equipment and ammunition. Anything you're not immediately using will be stored inside a strange sub dimension until you mentally summon it, in which you will instantly know how much ammo it has. And any weapon you wield will never need to be reloaded, as long as you have any ammo at all, your weapons drawing ammo from your ammo reserves.
You have all the weapons from the Doom Series, all fully upgraded with all of the attachments. This includes any weapon from the Chainsaw to the UAC EMG Sidearm to the BFG 9000 to the UnMaykr. You receive full ammo for all your weapons every day.
You have your very own Crucible Blade, the hilt being of your own design with your own chosen symbol, while the blade takes a shape of your choice. It is bonded to you, meaning only you can use it and that it can never hurt you in any way. The blade is even able to kill true immortals. And should you break of the blade and allow it to be absorbed by the remains of the on you killed, then they will become unable to come back from the dead. No form of resurrection or revival will ever work on the being you killed and let the blade be absorbed by. And unlike with a normal Crucible blade, yours will simply create a new blade the next time you turn it on. This one doesn't run out of energy and can be used all the time, even allowing you to send arcs of destructive argent energy at will. You also know how to create and bond new Crucible blades to others, though you will be immune to the immortality and no-resurrection part of the blades you create.
You have your very own Praetor Suit, which takes the appearance of your choice and is literally indestructible. It has built-in electronics including an artificially intelligent highlighting HUD, codex database, kinetic impact compensation system, thruster-boosted double jumping capability, the ability to harness the energy of the demons and other beings you kill to improve itself, and more, being open to further enhancements as well. It also has a closed environment, allowing you to survive in places like space or underwater without fear of running out of oxygen or getting pressured to death, or any other environmental problems.
You now own your very own Fortress of Doom, that is completely whole.
Instead of having so many empty rooms and useless space, it has instead an interior made for living in your own design, with bedrooms, a living room, a workshop for tinkering, a kitchen that is fully stocked with food and drinks, which are restocked every day. It has all you need for a perfect home in space, while also keeping the technology and main bridge of the original Fortress of Doom.
The basement is a prison where you can enter and find an endless amount of demons. It will only summon the kind of demons you want or fight and will not overrun you unless you want them to. The demons cannot escape from the prison.
The Fortress of Doom can not only open portals to anywhere in the world, it can also use a form of space-folding technology to reposition itself anywhere in the world.
The fortress will never run out of Sentinel energy, nor can it be hijacked by someone else.
The fortress also comes with a Vega grade A.I. of your own design, having the voice and personality you want it to have. You can also choose what sort of relationship you two have, from the A.I. being a servant to a caretaker to someone who loves you. But no matter what, the A.I. is irrevocably loyal to you. The A.I. takes care of the Fortress, operating and taking care of maintenance and controlling the tech, and has several drones it uses to help you, like supplying you with weapon upgrades, detailed GPS schematics, radio broadcast reception, tracking & locating items of interest and initiating trans-dimensional warp gates in order to transport you from place to place.
The fortress has several fabricator machines that can produce what you or the A.I. need.
The fortress also has a Technology Database inside its databanks containing all the technology and science from the Doom Universe, including that of the Maykrs, the UAC, the ARC and even Hell. This includes anything from how to build the BFG 10.000 to how to create Synthetic Argent, which still has all the capabilities of Argent without the need for souls, suffering and hell essence.
The fortress also has a fully whole Atlan stored inside, which can be operated alone as long as you have your A.I. to help you. It will never run out of Sentinel energy, nor will it run out of ammo. It can be teleported to and from the Fortress.
Inside one of the rooms in the Fortress, you have your very own Divinity Machine, taking the form of a large coffin like structure, which can grant others the same enhancement that the Doom Slayer received. This enhancement is guaranteed to work, and to not kill whoever receives it. This enhancement can be given to anyone, but you won't get any further improvements by using it again. It can be used on as many as you want, and you can make it so that they become irrevocably loyal to you.
Optionally, you may have a BFG 10.000 be placed somewhere on the Fortress, granting you access to your very own superweapon. It can be used as many times as you want due to never running out of energy, and can be aimed due to it being movable. It can be placed in whatever place you want whether it is on the main roof of the fortress, beneath the fortress or on an additional outside section made specifically for that.
Essence of the Involate Self
Drinking this essence confers you the blessing of inviolability of the body, mind, and soul:
You 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 a physical, mental, or spiritual nature that plague 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, copied, 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, copy, or manipulate your body, mind, and soul against your will in any fashion, no matter what method is attempted or used. Those who 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 into 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 prevent your body, mind, and soul from being affected by other forces without your consent.
Essence of the Blank
By taking this essence, you gain but one benefit:
Your potential becomes limitless. You can learn any discipline or skill set, even if you aren't capable of it, without forgetting it and practicing it into mastery, no matter how much you learn. Any abilities you have from other Essences will increase where possible and develop in ways beyond their initial purposes.
