The Final Bout/Strategies

Normal Party Setup
The most common strategies involve using 2-Hours, most notably Hundred Fists, Mighty Strikes, Meikyo Shisui or a group of Red Mages using Chainspell and a series of nukes with Stoneskin on. Other combinations, such as a tank and one or more Black Mages can also work.

Paladin tends to be preferred over Ninja as a tank due to the rapid speed with which the Waughroon Kid whacks the players. Also a Paladin can use Invincible, which will help negate most of the Waughroon Kid's attacks and weapons skills. A common strategy with Paladin tanks is to bring in any two damgage dealers. The Paladin runs in and uses Invincible either immediately, or once the Waughroon Kid uses Couterstance. Once the Paladin uses Invincible, the other two damage dealers use their two hours and bring the Waughroon Kid down as fast as possible.

BST/NIN x3 Strategy
Jobs Supplies The Fight
 * BST/NIN
 * BST/NIN
 * BST/NIN
 * Funguar Jug
 * Pet Food Zeta
 * Hi-Potion (Probably won't need it, but just in case of emergency)
 * Go into the fight, summon a Funguar pet, set your pet to attack, and cast Utsusemi: Ichi.  (Remember to let your pet attack first before you, because you want the pet to tank as much as possible)


 * If hate is on you turn your back to the mob and recast Utsusemi: Ichi if needed until the mob starts attacking your pets again.


 * Use your WS once the mob uses Counterstance since he will have incredibly low defense at that point.


 * Remember to fight behind the mob! He can counter your attacks!


 * Apply pet food (Pet Food Zeta recommended) as needed to preserve your pet as long as possible.

Note
 * BST/WHM can be subsitituted for one BST/NIN and still clear within the time limit.
 * If you get enough time to pull off a weapon skill and sic (seen as the funguars miss alot), theres a good chance you will have to rush to the armoury to complete this in time.
