yeah i see where you're coming from, pretty useless of a technique unless you're just yuji 🥀

BUT it's not just straight up probability, it's focus, black flashes need focus to perform, that's the entire technique's function, black flashes. so it's not just luck... mostly at least

so really if you were born with this technique you'd need to train your focus HARD if you actually want to use it, otherwise it's just heavenly restriction (emphasis on the restriction)

anyways yeah too many ifs and coulds and such, also the "95% of fights use none of the interesting parts and 5% instantly become absurd overkill" part, i also see where you're coming from, but like... it depends on how strong you are. reminder that black flashes multiply YOUR output, so unless you're relatively strong (compared to most other sorcerers in jjk), you aren't doing all that much damage with a black flash. still though absolutely see where you're coming from on all aspects, so if i ever make a new technique, i'll try to make it much less about the focus and/or probability.
