boss fight Rosso the Crimson

[Cruise Control]

I reccomend P cerberus. The M path has terrible stats.

Equip the Lucky S Barrel, it doubles teh amount of exp you get. Take gil instead of experience. And die. A LOT. Prefferably on a level you already pick up a lot of gil. Pick it up, die, and get gil instead of exp (which is doubled thanks to your lucky s barrel). Repeat.
