I just defeated Rousch(sp) for the last time. It was funny, I was like OOOOH one of those big things that steps on people. I killed one before, let me kill this one for some extra CP. Ran up to it, battle started, It took one step, Deathga. Everyone got hit for like 11k. Down we all went. I was like ooooooh, that's adamantoise, yea, i'll skip past him lol. Funny too because besides the non-primary roles, i'm all maxed out with everyone. I'm doing some non-primarys just for shits and giggles.

 

Right now my Sentinel has over 30k in HP.

The King Behemoth and the other guy that are at the start of the caves are great for CP farming. I can kill them in under 7 seconds. Goes for 13,200 in CP every time. Run up to the save point, rinse, repeat. I can get about 1.5 mil in CP an hour. Fang hits for 99,999 almost every time now

The trick with the big guys is to either put upgraded and stacked entite rings on everyone and do a normal battle, or summon with Vanille or Lightning to knock his legs out and then us Vanille to spam death.
