no there isnt much u can do in all my experiences the best thing you can do is train in
the surrounding area such as i did and when ur health is around 4k or 5k hell be extermely
easy to defeat anyways ima final fantasy fanatic ps it takes along time so u shouldve
trained along the road

just use animas overdrive oblivion it works for me.

If you were an ff10 addict you would know you can just put auto-phoenix on your chars, and
put overdrive-AP, triple Overdrive on a weapon, and fight the cactuar king with your cahrs
on stoic/comrade for about 5 mins and u get a tonne of AP points
