Golden Sun: The Lost Age - Star Magician (Optional) Boss Battle

Pants I...think...I'm...ready...for...this..!
Prepare yourself as you watch my all improved party take out the second hardest Super boss from the series! I remember when I first fought this colossus when I was level 37. I was totally wiped out due to under level. Talk about unlucky. I realize that I can't take out Star Magician (using my battle style which is without summons and djinn) unless I train harder and get better equipment sets!
The battle wasn't as hard as I thought it would be the second time after I got the equipments that I wanted. However, I really wanted to show my Isaac in this battle, yet I keep forgetting to do so in every video recording. I'll probably showcase him in the next video when I fight against Dullahan, the strongest super boss and boss in the Golden Sun series!
My party was exactly level 54 except for Felix who was level 55.
