Stone Arrghus

    To defeat Stone Arrghus, the boomerang is the most important weapon to have equipped.  You will notice that he has a lot of stones orbiting him, which you should use the boomerang on to pull towards you.  Once you have pulled a stone out of orbit, use your sword to defeat it.  Do this until there are no longer any stones orbiting Stone Arrghus.  Once all the stones are gone, Stone Arrghus will start dashing around the room, if it gets close to you, attack with your sword, and keep attacking until it jumps into the air.  After it jumps, get out of the way, when it hits the ground it will cause a shockwave that causes damage and stuns you, so avoid that at all costs.  Repeat this pattern until Stone Arrghus is defeated!
