[q=Doomsday]Doomsday is better than Doomsday sword. Equipping your party with Shdaow absorbing armor completely heals them and heavily damages the enemy. It can be very useful against Ozma.[/q]
Yeah, but if you don't want to use that equipment, then go with Doomsday Sword, and doesn't Ozma absorb shadow as well...but I guess it would still help for the shadow attack that he does (which might even be Doomsday, I've never actually fought Ozma, but I read all about it), if that's what you meant.
