King Crimson skips time, letting the user ignore cause and effect to go straight to their desired outcome.

The little face, Epitaph, sees 10 seconds into the future to determine the best possible outcome for the user. The user then picks the potential future they want, and use King Crimson, the main Stand, to time travels to it instantly, ignoring what had to occur to reach that outcome. So if, for example, the user needs to close the distance on someone with a gun in order to attack them in melee, and Epitaph sees an outcome where they do so, but gets shot in the process, they can skip straight to the effect, being close to their opponent, while ignoring the cause, running over while being shot.

However, if they needed to cross a busy freeway, and there’s no future in which they get across it within ten seconds, they’d have to find another way to cross.

It breaks the rules of cause and effect to allow the user to do things perfectly and instantly.

This is unironically the best explanation of King Crimson I’ve seen.
