His intimidation and power is the only thing making this boss difficult, that and the fact that he probably takes forever to kill if you don't have lightning powers or weapons. Stay behind him and cut of his tail (nets you a nice item along the way) and then just stay behind him. Do NOT LOCK ON to him. This way you can quickly look up if he jumps.
Just stay behind him and don't get hit by his ground pound and be patient. He's not that hard. --- PSN: Royta15 www.youtube.com/royta15
