To make this even better and faster, you can use the Phoenix Down, and if you leave the area before the xp and lp appear on the screen, when it shows you how much you get, you can re-enter and he will respawn without having to go 2 area away(you can also chain him if you are quick enough to get the loot before the xp and lp appear.)
