1) The average level of your current party determines the enemy's level. GFs have nothing to do with it.

2) Omega's level is always 100.

3) well, of course. Your GF levels don't matter when you're fighting the "superbosses." Having your characters lvl. 100 definitely helps, but it is possible to win the battle at lower levels. The most important thing you should worry about are your junctions, they will determine whether you win or lose.

5) You can manufacture Holy Wars without the Gilgamesh card, but it's a pain in the ass. You need to refine 10 Hero-Trials into a Hero, 10 Heroes refine into 1 Holy War-Trial, 10 of those refine into 1 Holy War.

rubah beat me
