I beat him. I finally beat that son of a bitch. I loved the ending though. Although it would have been a little better with the japanese song but fuck it, its amazing anyways. I love this game and would give it a 9.8 out of 10.

Congrats on defeating him ;) Did you manage to do 5/5 on him? There's a trophy/achievement for it.

Are you planning on continue the game to do the rest of the missions? 

o.0 are you kidding me?  OMFG!  Lol jk.  I will battle him again after i finish all the missions.  Im going to grind for a while longer.  I grinded a lot today.  I wanted to Gil grind for a while so i gave a shot to those big dinosaurs/turtle adamants and i killed one on my first try.  I think its name was Adamantortoise.  Its before rosch boss battle in cocoon.  I stayed there for like 3+ hours grinding.  I managed to make around 2 mil gil.  I bought lion heart(sold it by mistake XD), Fangs 31,000 gil weapon(forgot the name) and Bellandona Wand(I think i spelled it wrong) and managed to upgrade them to level them up to tier 2 max.  Now im battling more adamantortoise or w.e their name is so i can get that item that enables me to upgrade my weapons to tier 3 but all i have gotten from them is that ingot that sells for 150k.  With all of that i have made around 1-1.3 mil cp.   My commando, ravager, and medic roles for fang, lightning, and vanille are almost lvl 5.  Can anyone tell me where i can find the connoseurs catalog(Excuse me for my wrong spellings) which increases the rare item drop rate?  I want that item soooo badly!
