BLM > DRK > WAR > SMN is the kill order. The BLM is very resistant to Sleep. The elemental pet of the SMN can be slept as long it is not a dark elemental. Elemental Seal + Sleepga II will stick but the other kindred will build up a resistance to sleep. Lullaby will not stick, not even when its stacked with Soul Voice + Carol. Bind works just fine, however. I stick to a party of PLD, SAM/THF, DRK/THF, BLM/RDM, RDM/BLM, RDM/NIN. Poison Potions are useful to counteract sleepga, mages should bring refresh drinks and melees should bring hi-potions.
