Lol Actually once you get your hands on the White Robes item you can cast invisara on an ally with an item. It should help you take down Chaos with black mages and thiefs. But its only in the GBA version and PSP version of the game that this item is included so get the newer versions and then try it. I personally couldn't understand the old nes version. I got lost before reaching Garland x.x That's where playing the gba version was way better. Anyways I have team of 4 black wizards at lvl51 and i promoted them at lvl20 cuz bosses were an easy kill with all the magic i was throwing at em. Haven't taken down taigat or whatever her name is yet cuz i want lvl55 before i do that. and of course i never face chaos til they all 4 guys in my team are max exp. I always max out before taking down the final boss and idk why x.x anyways KIRBY HUG TIME!!!!!! (>^.^)>
RAWR!
