Drinking this weird essence that shifts to whatever color you're thinking about gives you the following power:
*This essence grants one and only one Absolute ability. That is the ability to check and control any outcome related to chance or probability.
*This means that so long as anything has a non-zero chance of happening you can turn it into a 100% chance. No matter if it is rolling dice for CYOA/Jump or accepting random rewards after accomplishing something in real life or CYOA or even something as mundane as answering a choose the correct answer question in high school.
*If you wish you can even force things that have a 100% chance of not happening to happen but this can only be done 4 times a month. With time however this limit will grow and eventually be eliminated.
*This can be gamed to quite a high extent such as making a spear always strike the heart after breaking through an indestructible shield, stop that very same spear from striking you at all, if you're standing at cross-roads and need to decide which path to chose to stay alive then you can choose a path and check the probability and if it is the wrong path then you'll be able to sense it and then choose the right path, you can game the stock market by checking which stocks will give you maximum profit.
*You can even automate some commands that allow you to protect yourself or execute things when involved in a situation that you can't keep up with. For example, if you're shot/injured then you can automatically execute "0% probability of dying" subroutine etc.
*If you wish, you can have a sort of in-built Gamer type observe ability that you can toggle which displays all sorts of probabilities/chances to help you make decisions.
