The fight is a pure burn fest just like most of the faction quests for relic.

setup: mnk, mnk, whm, pld (get 4 ppl to afk in party in town etc for full party buff) ACC 400+=> 99.999% accuracy when you have full party.

group 1: Everyone contributes to dps, do not try and spread out the party regen and spot cures with 1 or 2 SS's is more then enough to keep everyone up and the dps from the PLD is important. Keen flurry BfB Aura Pulse for the aoe early. Fist of Fire full time.

group 2: PLD grabs striped and kites, each mnk grabs a gobline and single target dps as fast as you can, fist of earth, use stuns to combo faster, shoulder tackle > aura pulse combo > pounce (stun again) howling fist combo > haymaker (stun again) etc u get the point. When both mnk's kill their goblins > bring stripped down below 70% to pop Fang.

Fang: incap concussive blow head quickly, fist of earth, trade stuns. Have WHM sleep stripped and PLD can tank fang or at least help DPS it down (defense down is HUGE). PLD can toss cover out and MNK's can fist of fire and really burn down fang fast. when fang is dead swap back to stripped.

Stripped is strait tank'd and burned as fast as you can, pop a mega STR pot if your short on time with hundred fists.

Main tricks to winning is speed/dps (you want to shoot for 110+dps on mnk i'm sure 130 is possible from a very well geared/skilled MNK), the whm sleep on stripped when fang pops (this really helps speed up fang's death and the cover lets the mnks go a lot harder).
