Panel A
Boogy uses his shadowform ability to cling to the outside of the fortress wall, seeming to slalom down the face of the structure, knee-deep in a crest of shadows. We can see the monster in free fall just ahead (below) him.
Panel B
Boogy grabs the monster with one hand and slams it into the fortress walls beside him as they continue to fall.
Panel C
Boogy, using the force of their shared momentum, scrapes the monster down the face of the fortress leaving a gruesome smear of ichor and viscera in their wake. The monster is a helpless tumble of limbs and flesh.
Panel D
At the base of the Fortress wall, bare feet from a lethal fall, Boogy pulls out of his slalom and slams the monster into a clutch of jagged rocks jutting from the base of the fortress.
Panel E
Boogy crouches against the fortress wall in defiance of gravity as the monster, bleeding and ruined, clings to the rocks, trying desperately not to fall to its death.
