Essence of theTotal Privilege (FGO).

Through this power you receive the complete arsenal of Fate servant sheets, one at a time, at least. A superior form of the Imperial Privilege skill. An Eidolon type power.

• You have become a Heroic spirit of a variable type. You have no fixed class, skills or Noble Phantasms. However, you can freely switch between any type of those you wish.

• You can incarnate into flesh and switch between flesh and spirit at will. This means you generate all the magical energy you need but you can receive extra by a master, even when you are in spirit form.

• You can switch between any power that you wish and can think of. Despite the name of the essence you aren't limited to fate powers, classes and skills. You have access to anything that has, does and doesn't exist. Your only limits are the number of your skills and your present power. If you try to use stuff like 'Galaxy Breaker Space Excalibur' when you're just starting out, then well, that's obviously not going to work out great. The same goes for your stats.

• You start out with 3 active skills, 2 passive skills and one noble phantasm. As you grow stronger, the number of your slots will grow as well.

• You have infinite potential, growing through training and time. But since you are a living servant, your power will increase relating to your fame and your deeds. You always receive a permanent boost when you mark history and a small temporary boost in areas that you are well know.

• At the start, your 'spirit core' is at the level of Artoria Pendragon on the original F/SN.

• Optionally: The powers of this essence may synergize perfectly with other powers and essences. An Immortal soul giving infinite magical energy without the need for using a skill, for example.

• Perfect memory, with infinite storage, perfect indexing, protection from harmful memories and the ability to move memories into hidden storage, replacing them with a mental note that you have done so and can restore them at will.

• You never tire of the joys of life and your emotions will never be dulled by the mere passage of time, adapting to cultural change over the centuries will never be grating.

• Freely travel the Omniverse, helps if you have a way to target a particular reality such as a form of media about it.

• You can arrive in any of the various timelines or worlds in the Omniverse, as many times you want, whether as a drop-in or reincarnate. Naturally, you can choose the time and place, with the circumstances of your birth or arrival at will. This can manifest itself in bizarre and strange ways like being summoned as a servant or stand power, or even possessing someone or something.
