everyday was different for the flies, because it was mainly during the week during the day so random ppl would be on. First day was hardest because we had no smns which make the fight a breeze, so we took a bunch of blm and kept them slept while an assortment of melee, sam thf drk mnk, took them down 1 by 1. There were a bunch of deaths on the first day. Total setup was: Blm Blm Blm Rdm Rdm Pld Pld Thf Sam Drk Mnk, and maybe one or two others. It was kind of hard like this because the flies never stayed asleep for long, so the mages were spending the whole time sleeping mobs and couldn't nuke(not that regular nuking does much, -ga spells suck because there's so many mobs, and the tier 2 spells you have, water fire stone i think, aren't worth much to speak of. Most days after that the basic setup was: Pld
Blm Rdm 2-3Smn
Some days there were various melee that leeched the fight, and one day there were 5 smns, which was fun. 3 40Smn can pretty much finish off all 10 flies with one round of Diamond Dust. Except for the day with 5Smn, we normally had 1 40Smn and 1 or 2 30-31Smn, so the flies would have like 10% hp after DD, so I would sleepga and we would finish them off one by one, which at that low hp was pretty easy.
30Smn > 40Blm FYI. even gimped the mini-smns were doing way more damage in one DD round then I would spending all my mp on -ga spells. Each fly had about 1500 hp, and avg DD did 350-550.
