Essence of the Reality Marble (Nasuverse)
Drinking this essence, which looks like a strange distorted fluid, grants you a Reality Marble
This essence grants you a peak human mind and body by the standards of Modern Era Fate universe. This means that you have a Genius intellect along with perfect memory, recall and indexing. Your body is strong enough to tear through buildings and can easily survive the same and can with training move faster than sound with matching reflexes.
With training however you can even reach physical and mental abilities only possible in the Age of Gods allowing you to eventually stand as an equal to all but the strongest servants and mentally you may even be an equal to Leonardo Da Vinci and Sherlock Holmes etc.
You have a total of 200 Magic Circuits of the absolute highest quality a human can possess both in Modern Era and even in the Age of Gods. Your circuits significantly surpass even the most talented members of the Blue-Blooded Barthomeloi family and even most Dragons will be found wanting and your talent in Magecraft is similarly at the peak of what humanity can achieve. At the beginning, your spells can vaporize entire buildings without effort and this can be trained up even more.
Both the quantity and quality of magic circuits along with your enormous magical energy can be passed down to your descendants without them degrading over generations and may even increase. This shall make you desirable indeed to the mages of the Clock tower who wish for powerful children.
This also grants you exceptional endurance and makes you an exceptional lover and sexual savant to the point that even the biggest thots in history such as Medb could be fully satisfied. You can reduced every woman into a puddle of pleasure. Have it as a freebee.
You gain a one time customization to your appearance and regardless of what you choose you'll be a 10/10 even in the older eras.
You possess a Magic Crest that is 3000 years old indicating that you family originated from the Era of the King of Magic. The focus of your family's magecraft, how many members there are, the spells in your crest, how loyal they are to you, their wealth and everything else about your family is completely up to you. Fanwank.
Note that the number of circuits you possess cannot be increased naturally but there are other options that you can figure out. While your circuits cannot be increase, in defiance of the normal rules the amount of magical energy can be increased through training, magical experimentation etc as though working a muscle. Your magical energy regenerates from zero to full in 30 minutes regardless of the size of your pool.
You may also decide whether you possess a pair of Mystic Eyes and a Sorcery Trait. However neither of them can surpass what the Modern Era's Mystic Eyes can do.
Now we finally come to the crème de la crème of the essence, your very own personalized Reality Marble. Before we get into this, however, it should be mentioned that you have enough magical energy available to keep up your reality marble for a total of 3 days at maximum usage and more if you're conservative. This is significant as even the strongest Dead Apostle Ancestors cannot maintain the reality marble for more than one night.
The rejection of the world on partial manifestations of your RM is significantly lowered such that Traced Noble Phantasms can lasts for weeks before disappearing and other similar benefits.
Reality Marbles are a manifestation of a beings soul, An inner world manifested through the power of your magecraft. As such the strength and abilities of them can vary from person to person. Your soul is exceptional and so is your reality marble. Whether in terms of strength or variety or efficiency your reality marble stands at the top among the strongest reality marbles.
You can have a cool chant or manifest it simply by saying the name or even without one.
You can customize your reality marble as you please this once after drinking this essence. You can add whatever features you'd like to your reality marble as well as combine multiple different Canon reality marbles to make your own. However you can only do it this once and once set you can neither increase the strength nor the abilities through the essence. Only the variety and applications can be increased and improved.
However this essence is compatible with other adventure formats like Jumpchains and CYOAs, so any RM gained from those can be combined into this essence to increase not just your own raw power but also all aspects of your Reality Marble as well as gaining all of the aspects from the ones combined.
For example, you can take Emiya's Unlimited Blade Works and improve the strength and efficiency to the point that it can match the Gate of Babylon in power while costing less magic or even reduce the cost of tracing the weapons outside to be negligible. You can have death become meaningless while your reality marble is deployed similar to Solomon's Ars Paulina allowing you to resurrect those who died in your world. Hell, if you want you can have your Reality Marble be a memorial where Heroic Spirits live allowing you to draw the power of those Heroes into you granting you their strength and noble phantasms or simply calling their weapons to your hands in a manner similar to UBW or simply calling those Heroes to your side to fight as Servants while also allowing the powers of UBW and Ars Paulina allowing to even create your very own personal Throne of Heroes Reality Marble. If you want you can even have Crimson Moon's RM.
There is however a limitation. While it is simple to grant you a Canon RM with increases in strength,efficiency etc where applicable, to grant you a customized RM you need the experiences that are required to grow the RM. For example to grow the Memorial RM you need to meet Heroic Spirits or at least know their stories significantly such a Emiya Tracing which allows you to know the History of the weapons intimately to the point of reproducing them or perhaps you can journey through Grand Order with the Servants and create memories with them allowing you to manifest them much easily than you would otherwise.
Of course there are ways to bypass the journey needed to grow the RM but that will have to be figured out by the user.
As a benefit, this grants you a form of reincarnation based immortality that allows you to reincarnate yourself over and over into different worlds of the Nasuverse such as Apocrypha or Grand Order.
You can replace Canon characters if you wish and regardless of all else you can keep all your memories,physical abilities, experience and powers into subsequent lives without issues. However, this reincarnation is restricted to only Nasuverse.
Your powers and abilities cannot be stolen, copied, suppressed, damaged or affected negatively against your will in any way. So feel free to punch Kiritsugu while taking his Origin Bullets to the chest, your circuits won't get destroyed. Also no matter what, nothing in your RM can harm you or go against your will in any way. Everything works as you like.

Essence of the Patamage
By drinking this Essence you'll gain a unique form of alpha reality manipulation.
The alpha reality is the origin of all realities. This means that you are manipulating the root behind all of creation to create your results.
This Ability is powered by a unique resource called "patafuel". You'll start with a moderate amount that will regenerate from empty to full in a few hours.
By burning enough patafuel you will be able to create any result imaginably. General ideas are possible but require more fuel than precise effects.
The cost is calculated by several factors, namely:
Duration: Toggleable effects continuously consume fuel, while timed effects take their amount instantly upon activation.
A toggled strength buff continuously consume fuel, a strength buff that lasts 30 minutes consumes its cost directly.
Strength: Effects of the same nature but with varying degrees of power consume different amounts of fuel.
A strength buff that allows you to lift 100 tonnes costs more than a strength buff that allows you to life 10 tonnes.
Area of Effect: As the affected area increases so do the costs.
A strength buff that affects a hundred people will consume more fuel than if it would affect ten.
Cast time: The time used to bring an effect into existence regulates its cost. Theoretically any effect can be created instantly.
Taking three seconds to create a strength buff will take significantly less fuel than creating it instantly.
Precision: Precise imagination about the wanted effect can lead to higher cost-efficiency.
This power takes the most direct approach, so just wanting a bolder to disappear would lead to its disintegration,
which is far more costly than the alternative of telekinetically moving it out of the way.
Difficulty: Results that are harder to achieve take more fuel.
Actually stopping time is significantly harder than changing your relative passage of time compared to others.
You can start "projects": A result that cannot be created at ones can be built over time.
If you wanted to create an item over a few weeks, you can build it bit by bit by pouring fuel into its project, whenever you can.
Projects do not come into existence until completion.
Trying to start a project costs fuel, proportional to the wanted effect
This power, despite its name, is not inherently magical in nature and so isn't affected by magic changing effects.
Being connected to the very core of existence this abilites is inviolable and so cannot be suppressed, altered, removed, copied, etc.
Essence of Purgatory
By drinking this Essence you'll gain access to your own Training-Pocket-DimensionTM; Purgatory.
Purgatory is designed to make you stronger by providing you with strong adversaries regardless of how mighty you become.
By default, it is a bleak, rocky surface with cliffs and mountains. You, however, can change its design to your liking.
Be it jungle, desert, a large city or flying island range. Your creativity and Purgatory's size are your limits.
This also extends to the enemies you'll be facing. You can design them in detail or think of a general template like human, wolf, destroyer of worlds, etc.
The dimension grows larger when you reach certain thresholds. If you grow strong enough to affect whole continents it becomes a planet, if you can affect a planet it becomes a solar system and so forth.
The strength of time dilation is yours to decide upon every entry.
To access it you can either teleport to it directly or open a portal if you want to take someone with you. People you take with you will also benefit from Purgatory's special perks.
Bringing other people with you to train activates dynamic difficulty so everyone involved can enjoy a nice challenge.
If you defeat an enemy in Purgatory a part of its strength becomes your own. If this enables you to gain new abilities is up to you.
You can decide to enter a specific training mode to focus on a single aspect of you like your speed or magic. Alternatively, you can train a specific weapon or skillset. Purgatory will provide you with enemies that fit the thing you're training.
Should you want to train with equipment you don't possess, you can let it be spawned somewhere near you at entering. Spawned equipment cannot be taken outside however.
If you don't possess the basics of what you're trying to train, you will automatically be equipped with it. Only the theoretical knowledge though.
Once you've acquired a firm grasp on the basics, further technical growth will come naturally to you.
You can somewhat change the difficulty. Although there will always be a challenge, you can crank it up to eleven for a hellish experience should you desire.
By default, you will not require sustenance nor age while inside.
Should you die, which is not unlikely, you will respawn at a safer point. All your destroyed equipment will be repaired upon respawning.
Purgatory is a place to grow and become stronger and not your summer house. Should you relax in one place for too long, waves of enemies with increasing strength will come for you.
Access to your Purgatory is yours and yours alone and cannot be prevented, taken away, copied, etc.
Essence of the Unnamed Darkness
By drinking this essence you become the Unnamed Darkness, an ever-expanding, all-consuming foreign Entity.
Your body becomes a strange substance that can change its physical state and doesn't adhere to all physical laws. Neither matter nor energy but something quite different.
Regardless of state or mass, you are always able to fly. The gravitational pull of objects can't pin you down.
Walking through time and space is as easy as walking through a room.
In the beginning, your body will be a cloud, roughly the size of a large cat with physical properties to an average adult human. You can harden yourself to match iron.
You possess the ability to transform your body into anything as long as you have sufficient mass to reach its size. A gaping maw with razor-sharp teeth, tendrils, a jacket or flowers. Creativity is key.
The substance your body is made out of can make everything it can make contact with, a part of you. This behaves differently depending on the thing in question:
Beings need to be killed before they can be absorbed. Upon death, they are automatically transformed into your substance and absorbed, provided you have contact.
Every part of their being is consumed to improve you. Abilities, powers, knowledge, durability, aptitudes, mass, simply everything positive. Harmful aspects, like a weakness to fire, are automatically sorted out.
If you, for example, kill an average adult human in your base form, you are two put into one. Twice the strength, durability, and brain processing power.
Aspects that can't be simply added like reaction time, skill, or aptitude are instead improved. Having a reaction time of 200ms and absorbing someone with 250ms, won't make yours 450ms but rather 150ms.
You are perfectly capable of mimicking everyone you have absorbed, down to their mannerisms and way to talk.
Since absorbed beings are unraveled completely in mind, body, soul, etc. you don't have to fear them rebelling or retaining their personality. There is only you.
Their memories will have no negative effect on you.
Entities like ghosts or liches also count as living for this purpose. As do androids or cyborgs.
Objects can be absorbed if you're capable of forming a surface large enough for them to fall through. This surface is extended from yourself.
Your substance functions like a hole for this purpose.
Should you want to absorb a tower with a diameter of 5 meters, you would need to create a surface with a diameter of slightly over 5 meters.
You can sever the connection of objects with the ground with your surfaces if you would be able to cut through the material providing said connection.
Objects that are not able to fall through, have to be encased instead.
Contrary to beings, objects won't increase any aspects of you except mass.
By default, they are not turned into your substance but stored. This can be changed to your liking.
If an object holds power or skills, transforming it, will grand these to you.
Liquids count as objects.
Energy can simply be absorbed and released at a later time.
More esoteric things like mana or spiritual, psionic, and cosmic "energies" can be absorbed to increase your own reserves or smelted together into one.
Souls can simply be used as fuel or be unraveled to strengthen you. While still being able to possess skills from when they were still connected to their mortal shell, this is not guaranteed.
After passing certain thresholds in your growth you will develop abilities on your own. These include: Space-Time Manipulation, Mental Manipulation, Omnilock, Creation, Nonexistence, and more.
The stronger you become, the stronger the powers you unlock do.
Beings can only fall through your created surfaces if they're weak enough to not pose a threat to you and are immediately killed and absorbed then. This is a safety mechanism to prevent destruction from within.
Your Body is comprised of two parts. The first is the visible one through which you interact with the world. The second resides in an otherwise empty universe inaccessible and inviolable to anything but you.
If the first part is damaged, substance from the second is drawn to replace the destroyed parts. This happens instantly and can't be prevented.
The first part can be recalled to the second.
Should you possess strong enough regenerative capabilities, you can stop the replacement process and instead heal with these.
The second part acts as storage for everything that was absorbed and isn't used by the first. As a part of your body, it can also be customized.
Stored objects are automatically organized and are unaffected by the passage of time.
The connection between the two can't be cut or prevented. Chain reactions that affect the first part can't be transported to the second. For example, an effect that destroys all instances of a certain type of matter could only affect the first.
Chunks of substances that are removed from the first part, like cut off limbs, are transported to the second.
Anything converted can be rebuild and transported to you. Beings that have been rebuilt do receive their powers but not their personality and will follow your commands. You still retain the given powers.
Do to your nature you can't be trapped, sealed, restrained by any means, and are unaffected by time manipulation. You're also immune to reality-warping since you're not a natural part of said reality.
Being a foreign factor enables you to break the rules of the universes you visit. If you can do it is another story but the possibility is there.
You do not possess a soul, hence any attacks that target it are useless against you.
Your mind is built alien and strange so attacking it is useless. This extends to illusions and other manipulations.
All this and the powers that you'll gain are part of you and can't be suppressed, altered, removed, copied, etc..
Even if the name might suggest otherwise, your color pallet isn't restricted to dark colors.
Essence of the Tri-Sage
By consuming this essence you inherit the knowledge, memories of the Tri-Sage.
This opens the door to three different paths to power:
12 Tiers of Magic.
12 Stages of Cultivation.
12 Ranks of Psionics.
Each capable of bringing you to multiversal heights if followed all the way to the 12th level. But beware, reaching such status is unheard of for most who walk these paths, and treading a singular one leaves you with weakspots.
The power of each level increases exponentially. While at the 1st you would, for example, be able to:
Shoot lightning or heal minor flesh wounds.
Punch through a brick wall or stop bullets with your muscles.
Throw a car or mind control a single person.
At the 4th you could:
Create megaton explosions or resurrect tens of thousands.
Casually punch holes through a mountain or withstand nuclear weapons.
Lift several city blocks or mind control their population.
With his knowledge and skill, the Tri-Sage perfected these paths to remove bottlenecks and pitfalls for his successor so that you can progress faster and with no fear of failure.
This inheritance is ingrained into your very being and therefore cannot be suppressed, altered, removed, copied, etc.
Essence of the Legatus
By consuming this essence you gain the potential to become the strongest summoner.
You now possess "slots" which dictate the number of summons you can have called to you at the same time. You start with two slots.
More will be gained by strengthening your powers through usage. This does not limit how many you can design.
Summoning:
Your core ability and the first you will gain.
You can create and materialize summons of your own design.
Design references not only visuals but also their (supernatural) abilities, skills, and every other attribute.
Summons do not have to be meticulously crafted in every aspect but can instead be archetypes based upon their abilities.
If not designed otherwise, summons are fully sentient beings with their own personalities, goals, and wants, based on their design.
They are by default one hundred percent loyal to you and will not take actions you would disapprove of.
Every summon possesses their own supply of mana, ki, chakra, or similar energies.
They require no sustenance and can be kept out permanently.
Their starting strength is at a respectable level for the setting you're in.
Summons grow in power alongside you or even on their own.
If they remember the last time they have been called is up to you.
You are NOT creating actual living beings with this power. Summons are mere constructs build by this power.
Should the be "killed" or unsummoned, they will not wait in a separate dimension or similar, but be unmade and, in case of a resummoning, recreated.
They take up a single slot per summon.
Partial Summoning:
The second ability you will learn, after getting familiar with normal summoning.
This will allow you to summon specific parts of summons to replicate their actions.
Like a dragon's head for their flame breath or a giant's foot to stomp your enemies.
You will not have to design a summon to use this. An archetype will be created temporarily.
Partial summons are not permanent.
This doesn't take up a slot.
Fusion:
The third and last ability you will gain after mastering normal and partial summoning.
With this, you can fuse with your summons and gain their abilities, skills, knowledge and/or even mannerisms should you desire.
It will require some getting used to, but after a while, this state can be kept indefinitely.
In the beginning, you can only fuse with one summon. This limit can be increased with training.
This takes up a slot per fused summon.
The esthetics of how summons arrive is up to you, just bear in mind that different methods may take them longer to get ready.
This power cannot be suppressed, altered, removed, copied, etc.
Essence of the Self Timeline Correction
Have you ever sat in an exam and thought to yourself "Damm, I really should have studied"? Well, no more!
By drinking this Essence you'll gain the ability to retcon your own actions.
If you, for example, have played video games instead of learned for your finals, you could change the action of "playing games" to "learning".
This reverses the physical consequences as well as your knowledge. For example, this would result in:
The game reverting to the state before being played. A build chair would revert back into its components.
You forgetting what happened in the game and how you've felt playing it. You'll still remember the action you have changed, just no details about it.
Gaining the knowledge you've studied for.
Changed actions have to be somewhat plausible. Dodging a bullet as a normal human is fine, dodging a nuclear bomb isn't.
To prevent huge butterfly effects, the changed actions have to have happened a reasonable time ago.
This power will warn you beforehand if a retcon would drastically change your life.
It will also automatically change the timeline to protect itself and hence cannot be suppressed, altered, removed, copied, etc.
Essence of What If?
I bet you have wondered how your life would look now if you had done something different, if you had told your boss your opinion, or if you had just asked her out, I mean, she was clearly into you, you idiot, are you blind?
I digress; well, now you can.
By drinking this essence you'll gain the ability to create parallel timelines for different scenarios.
Your power works through setting a time and a scenario that will play out.
You can create specific scenarios like "What if I had won that fight" or broader ones like "Let's see what happens if I behave differently here".
Every time you use this power, a new timeline is created. You can physically move between these timelines at any time.
When changing timelines you will reenter when and where you left.
Timelines can be "caught up" to your chronologically most advanced one. Upon entry, you will be immediately aware of the changes.
Your powers can also create impossible scenarios like "What if I suddenly gained superpowers" or "What if I stopped wasting so much time on Twitter".
It will also automatically change the timeline to protect itself and hence cannot be suppressed, altered, removed, copied, etc.
