I pretty much have all that you listed. All four of my characters absorb Shadow damage and two of them absorb Holy damage (the other two don't need too because their level isn't a multiple of four) so Lv 4 Holy doesn't hurt, it even heals two of them. No'one level is a multiple of 5, so that negates Lv 5 death. Flare and Flare Star always kill one of my party members. I'm right in thinking I can't reflect Flare, right? But I can reflect Mini? Because that can be a b1tch. It's Meteor and Curse that hurt the most. Meteor does 9000+ damage on 3 of my characters if they're at full health and Curse either kills everyone or takes them down to low health with mini and poison.

Have you got any suggestions for party members to use? If I go to Memoria and get Vivi's Mace of Zeus, will I be able to get back to the world map? Doomsday would help a lot.
