Essence ofCard Copying

By drinking this Essence, you admit that your work ethics are atrocious…

• Gain the ability to perceive the 'cards' possessed by any entity, these cards are representations of that entity's skills, knowledge, abilities, attributes, traits, affinities, bloodlines and power. The generally positive pieces of their existence, the things that they have or can do that you want for yourself.

• You can copy these cards and gain the same level of skill, experience and power in that skill or ability, equaling the proficiency of whoever you took it from. Copying the card won't affect the person you took from in any way.

• Cards will labeled between being ranked S-A-B-C-D-E-F, with F-ranked cards being sort of useful in specific circumstances and S-rank cards are things equal to Isekai cheats, wishes from R.O.B.s or even other Essences. As you might imagine, S-rank cards aren't commonly or easily found.

• For example: copying someone else's martial arts skill will give you skill, knowledge and experience in martial arts equal to theirs, copy an ability and gain that ability at the same level of power that the original holder had it at, copy the amount of magical power that someone has and feel your own rapidly increasing to match theirs and so on.

• You can even copy the unique abilities and properties of objects too, so for instance: if an artifact uses healing magic to heal then you can copy that same level of healing magic and use it without the original artefact.

• You can also copy the cards of any entity that is sealed away but within your range, so you can copy the cards of things like the entities inside DxD's Scared Gears, the Tailed Beasts from Naruto.

• You can only copy one card per entity or object, so if you copy something from someone then you can't take anything else from that person so be careful in what you take from them.

• Copying similar cards of an equal rank will increase the rank of fill in the gaps in whatever knowledge you have that the other card didn't, eventually it will naturally evolve into a higher rank of card after enough cards of the same rank are copied. For example, copy enough F-rank martial arts cards and yours will evolve into E-rank martial arts.

• To copy someone's cards you need to be within 25 meters of them, and the copying process is instantaneous.

• Gain a mental library of all the cards you possess with their descriptions and ranks.

• At any time you wish you can gift any card or number of cards from your library to someone else. This will cause you to lose that card so be careful in handing them out.

• Training and growing more skilled or more powerful can cause cards to evolve naturally, so you don't need to purely copy cards to get stronger.

• This Essence was inspired by "Skilful Reincarnation" by Crossedge. It's not an exact copy of the protagonist's cheat because this is an Essence, the whole point was to be more powerful than the original.
