pretty much you wont need to do anything on blm, but really for your first fight i'd just wait till you see somone shouting that they're running it, not like its uncommon. the wings close after it uses gyre charge, oh and dont forget to buy and bring a doom screen, use that allong with your brew. and remember if you are double weakened you wont be able to do ANY magic damage, including magic WSs so your brew will be wasted, so stay back, keep SS and blink up, and run like hell if he draws in. also, brewing gives you 999 of all stats and 9999 HP/MP so stats on gear other than haste MAB, non statpoint stats, are worthless. you'll be amazed how much damage you actually do, and you are unkillable (except by death/doom) so dont worry too much, sub whm, hit it with earth crusher a couple of times, he'll be dead before your brew's half gone
