You should be fine, at least if you have any HP-stealing weapons. A Draw weapon, for instance, could take 30 HP from Falz per special attack. So you should save any such weapons you find from the Ruins, particularly busters (as they're pretty accurate). If you have such a weapon, bring it along and use it on his second form (virtually eliminating the need for mono/dimates during that half of the battle). If you have other characters at higher levels, see if they have a weapon like that to give to your HUcast. Besides that, just bring along 10 monomates, 10 dimates, and a shield with decent fire and ice resistance.
