Kill Draygon in one hit
As soon as the boss fight with Draygon begins, note the four turrets firing electricity from the walls - two on either side. Before Draygon even shows up, blast away all four turrets with charge shots. See how the turrets spew out electricity after being killed? Equip the Grapple Beam and get ready to use this to your advantage.

Instead of fighting Draygon the normal way allow him to grab you. While he's swinging you about the room use the Grapple Beam to latch on to one of the panels on the wall that was once occupied by a turret. The electricity will go through the Grapple Beam, through your suit and to Draygon himself. Samus will stay locked on until Draygon dies.

Secret Attacks
