Essence of the(Future) Master of Essences

This Essence tastes like royalty, sovereignty, and power.

• Upon consuming this Essence, you get an unlimited, updating list of all Essences ever made (including ones made after this Essence) tucked squarely away in your brain. You can search through this archive with a thought, and find any Essence in it based on any sort of search criteria you feel like, such as looking for sex & sexuality Essences, or looking for wealth or royalty Essences.

• When you consume this Essence, you gain a single slot which you can fill with any Essence you want. As soon as you fill this slot with an Essence you gain the Essence in question, but if it's Essence that requires training to master (such as Essence of the Unnamed Darkness or the Essence of the Golden Wrought God) still need to be trained to be mastered.

• Once you gain sufficient experience with the first Essence you gain, a new slot which you can fill with another Essence. How much experience it takes to gain a new slot depends on a number of factors, with the most pressing being how powerful the Essence in question is (the Essence of the Hentai Orc is weaker than the Essence of the Anti-Immortal, that kind of thing), and how much experience you have with thematically similar Essences. It is harder to gain experience with more complex Essences, and "experience" is gained when doing things at least somewhat related to the Essence in question (You wouldn't gain experience with the Essence of the Hentai Orc by going to a library or volunteering at a soup kitchen, but you would gain it by working out or having sex).

• Over time you'll gain the ability to get more than one slot when you gain new slots, with no hard limit on the maximum you can get (eventually, if you wanted, you could master every Essence).

• Contradictory elements between Essences do not harm you (The Essence of the Non-Believer would not harm you if/once you become a deity through some other Essence, for example).

• Essences cannot harm you in anyway, with negative elements/drawbacks inherent to them being nullified.

• You can create copies of Essences you have in your slots and give them out to other people. You can cancel out the Essences of yours in the systems of other people, stripping them of their powers. Experience gained by others counts towards your level of experience, so this can be a handy shortcut for you to master an Essence.
