Can ask which grid you used? And the monster capturing = easy, just annoying not being able to get the overkills for items and AP, when you don't need a gazillion AP for one Sphere level :S (saying that, I currently have 3 or 4 characters with 99 moves on a fully activated grid (expert grid), because there's no need for them to go anywhere until I get more filler spheres
)
I was thinking of taking Yuna (Nirvana weapon = 1MP cost) and doing a one vs one on the Nemesis arena monster using Auto-Life... would be tricky, but she
can hit 99,999 every hit...
