KHFM - Hercules , No Attack, Barrels Only

This was part of my first "Friends Only" playthrough, and i was completing as many side stuff as i could and ran into this, Fire spell was my only option for damage but i would most likely run out of magic eventually. Then i thought maybe i can use the Barrels to do damage, and decided to do the whole fight with only using the Barrels. Lol. ...This "Hero" is weak! XD
