Wait for the global Sova to begin climbing the wall below the door. Have Reserves set to manual and couch jump up above the Sova as it turns the lip of the ledge. Before touching the Sova, pause, so that Samus will recieve a small damage boost followed by pause screen appearing. Set Reserves back to auto which will end Samus' i-frames enabling a second damage boost. Without Morphball, this requires a blind damage boost.
