In the Mines of Judgment is a room that has a Bugbear, a Slogra, and a small ledge overlooking the room. Equip the Enchant-type soul Draghinazzo (stops flinching after taking damage) and destroy the Bugbear. Destroying Slogra is optional. Press R to activate Guardian-type soul Bat Company and fly into the ledge, just barely on the edge. Deactivate and Soma will be crouching on the ledge. Slide twice in the direction you are facing. Once you fall off, keep pressing B to jump repeatedly. This may take a few attempts, but Soma will continually jump until he touches the ground.
