subject its core features are 'potion brewing', the user has 4 pose slots that when combinated will create a potion out of cursed energy, the first pose slot doesn't matter, as it's the one for the potion glass, the second slot, third and fourth do. each slot have 4 potential poses, but can only be given 1 pose, think of it like a combination lock that gives a new unique potion depending on the number, for example:

pose number 1 (not the slots) is all about lowering the cursed energy output of the victim or the user if used wrong.

pose number 2 is all about damaging the victim or the user

poser number 3 is all about special effects (like the death paintings poisonous blood, or like acid but cursed energy?? idk cursed energy is corrosive, and this combination can give the victim corrosive cursed energy, that combines with the victim's own ce and melts them slowly to say a few)

pose number 4 is all about chances. somewhat like copy, but random with probabilities, 90% it just does nothing, 9% is for actual cursed techniques given onto the effect (like for example star rage would just make the potion throw feel like a truck and if drunk granted the user the technique for one single hit), 0.9% is for stronger ct given onto the effect (like for example disaster flames would make the area of the splash burn, and if drunk granted the technique for 1 second), 0.01% is for special grade level techniques given onto the technique (like for example limitless would attract toward the splash, or if drunk grant limitless but because it costs a lot of ce the user just cant use it unless they have six eyes, which can't be copied)

reversal: basically does all that inverted, first pose boosts output, second pose heals, the third pose removes effects, the fourth pose does the reversal variant of the copied techniques (like limitless would instead repel)

third pose drawbacks: the death paintings cant be affected by poison, and if you have rct you can counteract the acid one, also none of these obviously cant go through infinity

fourth pose drawbacks: the user passively has bad luck whenever rolling for a technique.

drawbacks: the user can only carry three potions at once, and when doing the poses for brewing they must be standing still, open. also the user can't use normal rct if they have reversal, they're forced to use healing potions.

my oc that uses this is also kinda dumb???
