I was wondering just how many ways to beat those two notorious hidden bosses there are. You can't just rush in with a "me strong, me smash" type mentality, it really makes you think. Because of this, most of the strategies I've heard have been pretty clever. The one I created for Omega was to have one character with the elemental sword spells (!sword i think) and the two swords ability hit him twice with a high level bolt sword while the other three characters used the bard's hide ability to avoid Omega's counterattacking and then used white magic to revive the attacker. I reapeated that 3-4 times and Omega died. For Shinryu I used the !shot ability and two swords, and the hide-heal tactic from the Omega fight. Without the vicious counterattacks of Omega, Shinryu went down almost without a fight. That's what I thought of but I know that there are better one's out there.
