Essence of Talent
Drinking this golden, gleaming liquid seems somehow unfair, but it's highly enjoyable all the same.
* Your natural aptitude for any activity or field of endeavour is beyond ridiculous. You are by far the most talented individual that has ever lived, to the point that the people formerly upheld as supreme geniuses before your arrival would look positively dull and inadequate next to you. This unprecedented degree of talent applies to any and every activity that you have even the slightest potential for at all.
* Your talents are not only unprecedented but exponential. The more you learn and develop, the faster and easier it becomes to keep learning and developing, endlessly. Your skills are only limited by the ability of your body, mind, and/or soul to execute them. You could soon enough advance your mastery to the point where inventing or discovering incredible new skills and techniques could easily be done in mid-fight, if you cared to.
* Your instincts for avoiding self-harm or dead ends to your development will be flawless. Nothing you learn will have any costs, setbacks, backlashes, or handicaps that you are not aware of and voluntarily and of your own free will choose to risk. If you ever fall to something like Dark Side corruption, the madness of the Warp, or suchlike, it will only be because you went in with your eyes wide open and willing to pay the price of using such knowledge. You will never suffer any harmful effects, corruption, or loss of sanity merely from knowing about such things in theory, or from your talents in general. You will never have to worry about suffering boredom or loss of empathy from being 'too good' at things.
* Your only limits will be those absolute ones imposed upon you by the nature of whatever universe/multiverse/reality/etc. you are in. Sheer talent alone might not make a purely human body capable of living forever or punching through a planet or suchlike, but if there were any possible way at all that a sufficiently talented and motivated individual in your position could work past a growth cap or a limitation, or tap into a given source of power, then you would be able to find a way to do so with sufficient effort.
* To give you a fair start at developing your talents, at the time you first drink this Essence, you will be cured of any and all physical ailments and disabilities. You are also made aware of any mental illness, disorders, disabilities or other conditions you may be suffering from and may have any or all of them cured at your discretion. You will also receive a one-time appearance upgrade based on your wishes and idealised self-image, with the exact details of your build and "endowments" being up to you.
* As a special bonus, you receive full control over your fertility and other related buffs.
* Finally, your skills and abilities will never degrade regardless of disuse, lack of practice, etc
