Forestep

Though the predictive model allowed him to bypass reaction speed by replacing reactions and reflexes with predictions and foreknowledge, there were limits to this. It could not help him evade attacks that were far faster than him. At least, not as he and it were as they currently were.

For example, even if he tried dodging well ahead of time due to having foreknowledge, the Root would most certainly alter its trajectory to match its dodge. If it could see him moving much ahead of time out of the way, then obviously it would not simply hit empty air, no, it would instead shift to attack the dodging Rui.

This meant that he could not dodge too much ahead of time even if he knew it was coming well ahead of time. He needed to time the evasion maneuvers just right, it could not be too much of a headstart.

However, because Rui was so much slower, he could not dodge it if he didn't get a headstart either.
