So here is how i did the BCNM.... in MSPaint form
THE PT SETUP
WHM/BLM - Me of course, Dedicated Healer of the Bard until the Black Mandy was dead.
RDM/WHM - Dedicated Melee Healer, until the Black Mandy was dead
BRD/
NIN- Probably the best thing i've ever seen! Bard can use Utsusemi to take some of the hits he normally would have taken. Max him with some Taznazian(sp) Tacos and alot of CHR equips
you'll be set. Seriously, does tbe bard need to or have the time to heal him/herself? SAM/WAR - Damage Dealer DRK/WAR - Damage Dealer PLD/WAR - Tank... kinda. In All Honesty we should have dumped the PLD. lol, the dark knight kept pulling hate so the PLD was kinda useless.. but then we had a uber dark knight. After the first fight, our DRK went and got +Def Gear and pretty much tanked the rest of the time... My ideal setup would be WHM RDM BRD and either SAM's or DRKS for the rest. but thats me and my previous experience OUR STRATAGY! Soon as you get into the BCNM, Buff up WHM - Protectra/Shellra - Stoneskin/Blink - Reraise (can't be to careful) - Pop a Cookie and Rest(DON"T USE OTHER FOOD! ie. Pies! the added mp doesn't help if you can't regen it back later on in the fight... Stick to cookies, Ginger/Wizard.) RDM - Stoneskin/Blink - I dunno, what ever buffs you need ^.~ - Pop a Cookie and Rest(DON"T USE OTHER FOOD! ie. Pies! the added mp doesn't help if you can't regen it back later on in the fight... Stick to cookies, Ginger/Wizard.) BRD - Ballad for the mages - Utsusemi for Blinks - Food (Tacos)
- After Mages have MP Cast needed buffs on Melee to get them ready... what ever those buffs may be. (hey i'm a WHM, i know my job, but ignore the rest)
Melee - again.... i'm a whm... do your thing melee
*Please refer to the Painting below* Step 1. Bard runs up and casts Foe Lulleby on the Black mandy. This gets aggro from all of the white mandies and they all come charging after him. he then moves down into the entry way and casts Horde Lulleby on them to pull them to sleep. WHM stays with the bard and is solely devoted to curing the BRD. First time i heard this i thought it was useless, and i should try to heal both(thats what i do in exp party afterall) Don't try it. thats what the RDM is for. he can take care of them. and when 6 or 7 of the white mandies wake up to attack the bard... thats 7x2(mnk attacking) 14 hits the bards going to take all at once... he needs the dedicated healer... again, the reason utsu is needed. Step 2. AS SOON as the BRD finishes casting Foe Lulleby, the Melee and the RDM run in. Melee beat the crap out of the black mandy till its dead. DRKS cast Stun when ever needed. and SAM has his stun WS macrod if needed. We did a Distortion Skillchain which the RDM bursted on when he had time... Not Nessecary, but fun. Step 3-4. After the Black one is dead, the melee and RDM come back and one by one wake up the white mandy and kill them all. Designate someone in your party to be the first one to wake up a mandy. DO NOT WAKE UP THE RED ONE THE BRD IS ALREADY TARGETED ON! This makes for simple problems of targeting and what not. Also, there is no need to pull the mandy your attacking away from the group of slept mandies. we tried this, but the hate was so great that he'd just come running back very shortly, and caused more problems then what it was trying to cure. OK, this is what we did naturally, (unplanned) and worked extreamly well for us... ended up becoming part of our offical stratagy. Who ever has the most MP(RDM or WHM) after the Black mandy dies is the first main healer. The other Runs back pops, a yagudo drink(if necessary) and Cookies(REQUIRED) and rests up back where the black mandy was just killed. when we did it it, i almost always was the first one to need to heal, so thats how i drew it in my example. After the RDM runs out of MP, he'd give me a /tell telling me to get up and take over. Sometimes converted but usually rested to full with cookies/juice. in not to long, all the mandies would be dead... and we'd claim our prize. THE PAINTING
THE RESULTS We did so so on results. we did the BCNM with the intention to get Erase for 2 whitemages. so money was secondary. Ended up with 3 Scrolls of erase, and various misc. Goods. Scroll of erase was 700k at the time... so just with that we made 2.1million devided by 6 equals alot of gil for everyone... and thats just counting erase.
After we gave away phalanx to the RDM 2 erases to the WHM(Me, YAY!) and a WHM in our LS. we sold the rest and everyone walked away with 200k i beleive... can't remember, tis been a while.
We did this BCNM 5 times that night, were 4/5, one attempt in the middle had a bad mishap, forget what happened and everyone died. oh well.
FINAL THOUGHTS
Its not a hard BCNM, with many good rewards. Not every time did we get good drops, but total we got alot. you don't need to do exactly what everyone else has done to win this BCNM. Just remember a few key facts.
DON'T PANIC
our PLD when we did this took a Flood to the face and died right away on one fight. We were able to raise him and keep fighting and have him unweakened by the time we were on the white mandies. It felt like it didn't even phase us. So when sh*t happens, stay cool, keep doing your job. and let the super cool WHM raise the poor SOB.
Good luck all. Hope this little rant helps you all out. Dunno why i posted it.

But it brought back good memories. PEACE!
