To defeat Armogohma, you must take out your bow and arrow and wait for Armogohma to open its eye. (it opens its eye right before its going to shoot a lazer at you). It will then fall to the ground. Go to the statue near it and use the rod on the statue. Then attack with the statue. Do this 3 times to defeat Armogohma. The 2nd and 3rd time doing this, Armogohma will lay little spiders on the ground. After hammering Armogohma 3 times with the statue, its eye will fall out. Just chase it and hit it a couple times with your sword. Then Armogohma should die.
