I definitely need more levels and Elixirs for Omega with this team. Just lost a fight that was somewhere between 1-2 hours of Omega because I completely screwed things up and lost control. It doesn't help that my team couldn't consistently survived Atomic Ray with Shell and if I accidentally reflected one, that's a lot of healing for the boss. I'm not sure how many cycles of his pattern I survived, but it's very survivable if you don't trigger the counters until he has used Search.
At least I can quicksave for Crystal Dragons then use the Wonder Rod as an item for Reset if I get the Dragon Lance. Natural Blue Mage, Summoner, Geomancer, and Dancer is not a good team for this. I should probably try to get the Rune Bell for Faris so that maybe she can do a little damage to Omega and provoke some of his counters. The Tinkerbell doesn't seem to do damage, but the MP crits should.
Chicken Knife Sword Dance when it procs was a bit over 3,000. Boosted Ramuh was around 1,000. I was only attacking Omega after I reflected one of his Searches so that he would target himself with the counters so that I wouldn't have to worry about the Encircles and Rocket Punches, and the Mustard Bombs would hurt it some.
Edit: I should also probably grab a Silence immunity equip for my Summoner. Having to lose a chance to attack for a cycle because Lenna got silenced isn't cool.
