Dismemberment Brigade/Strategies

conventional
kill order should be BLM > PLD > DRK > WAR > MNK > RNG

fight is very similar to San d'Oria M7-2 BCNM. You should have BLM with sleepga 2, at least 1 RDM/WHM (main heal), PLD tank, and a stunner (either BLU or DRK/SAM). The other 2 members can should be DD. DRG/SAM and RNG/NIN shines in this BC, due to the fact orcs tend to take somewhat more damage from piercing weapons. PLD must cure the BLM between sleepgas to cause the other orcs to build hate up for the PLD.

All orcs can be slept but the BLM with Sleepga II is recommended as they will start resisting lullabies, and Sleepga is not available with the BLM sub. 2 BLM is safer, they can set up sleepga and stun orders.

BLM uses Elemental Seal + Sleepga II on orcs, then everyone pops a poison potion (to avoid being put to sleep by the Orc BLM's own sleepga spell. RNG will pull the BLM orc, and melees should try to kill it as fast as possible using TP as soon as it is there (no skillchain on the BLM).  The BLM orc is somewhat resistant to silence, so it is very important to stun his big spells.  It should die before the others wake up.  After it is dead, poison potions are no longer needed.

PLD orc is pulled next. He can be silenced but difficult to pull off. He needs to be kept away from other orcs so it will not attempt to cure them to wake them up. Around 50% it will use its 2hr ability, so melees should turn back to them and nukes should be used if possible. Once it is down, the hardest part of fight is over.

DRK orc is pulled after the PLD. Due to its very low defense, he will die quickly. When he uses blood weapon, melees should scatter away from the orc, Stun should be cast and the PLD must drop target and run away from the orc for the next 30 seconds. Melees and mages must be careful not to pull hate during this time or it can easily result in death. This tends to happen with this mob around 50% health. Shadowbind can be useful in forcing this orc to cool down.

WAR orc comes next. He does not last long. Use Stun and/or Flash when he uses mighty strikes. PLD can run around the circle for 30 seconds if needs to be, but Shadowbind will not be ready at this point.

MNK orc should be attacked from behind. PLD should switch to earth staff for this one and not engage in it. At 50% the 2hr will go off, use Stun then have the PLD kite the orc while nobody else gets in front of that orc.

RNG orc simply stands and shoot the tank until low health, so the PLD can stay outside its melee range and tank from a distance using cures, especially targeted to the black mage (which should have considerable hate). Once it hits low health it will use Eagle Eye Shot and starts meleeing like a regular orc.

manaburn
This BCNM is also possible to pull off manaburn, using 6 BLM/WHM (for stoneskin and blink) with best gear possible for level 60. All must eat poison potions (the BLM orc could respond with a Sleepga), 5 will use their strongest waterga spell while the 6th uses sleepga II just as the orcs come. This plan requires a lot of coordination. the BLM will rotate on the Sleepga II until all orcs are dead.
