I ran away frequently in the higher levels of Via Infinito and my party is doing damage in the high 8000's. It's kind of like the Brave Knife in FFV.

Finale is suprisingly lackluster in actual use. Not much more than a glorified punch, along the lines that Trema does. Be that as it may, the real prizes are BHPL and BDL (with only two spherechanges to activate as opposed to the four needed for Higher Power GG).
