The alternate version of Course Correction that may be the Dreadful Foe of the 3rd floor especially when the player's Light is below 100, Route Revision is, for all intents and purposes, identical to Course Correction, but the Pathshaper is switched by the Lingering Pathshaper which spawns Pathshaper Fractals when taking damage twice as often in addition to possessing greater HP and ATK. This makes the Lingering Pathshaper even trickier to deal with, as its ability to spawn a mass of Fractals at a rapid pace can (and will) overwhelm the player's Operators.
