Instructions
Use the Z-target on each of the three connectors that hook Barinade to the ceiling. Throw your boomerang to sever each connection.
Back off and hide near one of the pots as the jellyfish emerge. Run in when they stop spinning and kill each one individually as you dodge the electricity blasts. If the jellyfish begin to spin again before you get them all, return to the edge of the room, then continue your attack when they stop.
Use the Z-target to lock onto the main part of Barinade's body. Hit him with your boomerang a few times to stun him. Move in and destroy any remaining jellyfish.
Lock onto Barinade and continue hitting him with your boomerang. Move in when he is stunned and slash him with your sword. Repeat the process until Barinade is defeated.
