If Kraid is alive, use X-mode on the thorns to gain blue speed. Hold an angle button to turn around while retaining blue. If needed, arm pump to get close to the ledge without touching it. While in X-mode on the thorns, Samus' will be flashing as i-frames periodically refresh; by timing the shinecharge and X-Ray release to happen soon after i-frames refresh, a second thorn hit can be avoided.

Requires:

}

Exit condition:

}

Dev note: If Kraid is alive, leaving with a horizontal damage boost is also possible, but not easy to model.
