Essence of theArcane Book

"Knowledge Is Power", both self evident and true enough on its own but with magic being involved it suddenly becomes more literal. Having drank this Essence you gain a book, an omniscient and comprehensive grimoire of all things magical, mystical, supernatural, occult, etc.

• Every magical system and spell, any and all permutations, methods and means, recipes for potions, blueprints for artifacts, secrets long forgotten or destroyed, details on the various magical beasts from throughout all of existence or the magical uses/properties of mundane ones, the pertinent events to a magical setting's history, etc. anything that is magical or magic adjacent can be found within.

• The information you're looking for is always presented to you. This can be anything from a specific method or desiring an end result and a way of doing it being demonstrated to you. Additionally: the book also comes with animated loops showing just how something needs to be done for visualization purposes.

• You can task the book with creating a never before seen or created method of achieving something using the magical system and/or resources you have available, so if you want or need a way of doing something then the book will design spells, artifacts, potions, tools, rituals, etc. that could accomplish the task you set assuming that one didn't exist already. For example: if you wanted to get the Horcrux out of Harry's head without him dying, the book would create a method that could do it using the HP magic system and while obeying the absolute rules and limits of that system, assuming that it was at all possible and you only had access to the HP magic system.

• You can conjure pages and books that have only the specific knowledge you desired for them to have from this book, so you can, if you wanted to, share the knowledge within the book with others without exposing the books itself. Complete copies of the book can't be created, at most only a single book that comprehensively details a single magic system can be created.

• Keep in mind that when you hear 'something is impossible' for a given magic it might just be because the method is still undiscovered or maybe someone regarded as powerful or knowledgeable tried and failed so they took that person's word for it. This means that if there's a will there's almost certainly a way, it's magic after all: the whole point of it is to turn the impossible into the possible.

• This Essence doesn't grant you any sort of magical potential or talent that you didn't already have or gain from another Essence or being in a specific setting. There MIGHT be magical ritual to grant you the potential somewhere in the book but whether it can be done with the means you have available is a different story. Best hope you're lucky~.

• You can choose whether the book is mental or physically in your hands. If the book gets damaged it can be repaired with a thought. You can choose if the book is perceivable by others, even selectively if you wished. It can be read mentally if you wanted to. It can be summoned to your hand or banished to the ether when not wanted or needed.

• While others might not be able to perceive the book unless allowed your mind may not have that same courtesy, so your mind and memories can't be read, tampered with or attacked in any way. Additionally: you can treat memetic/information hazards like the annoying little viruses that they are.

• Upon sufficiently mastering something from the book, anything really, your max magical power/energy pool grows by 2% of your full capacity. Being able to preform something reliably and repeatedly is good enough for 'mastery'. It also works on energy pools that are normally fixed or incapable of growing for whatever reason. If the magical system you're working with doesn't use energy to work (Harry Potter/Charmed) then instead the potency of your spells will be increased by the same amount.

• You consciously and subconsciously control and manipulate your magical energies with perfect precision, fluidity and efficiency as well as changing the potency of your spells on the fly to suit your needs and/or desires.

• Combine this with a magic granting Essence and you'll be the most knowledgeable or the most powerful (or both) mage in no time.
