3x BST
Jobs 3xBST/??? (any subjob will do)

Supplies
 * Any uncapped Jug
 * Pet Food Zeta just in case

The Fight


 * First get a nice cool drink (alcoholic or non-alcoholic)
 * Get your favorite snack
 * Enter the ENM
 * Make your pets attack the Eft
 * Sit back and enjoy your beverage and snack until the Eft is dead (apply Pet Food Zeta if necessary)
 * After Eft's death, open the Armory Crate for a hidden surprise!

RDM/DRK (or RDM/WAR) and WAR/NIN
Jobs RDM/DRK or RDM/WAR WAR/NIN (other melees may work)

Supplies
 * Antidotes
 * Enmity gear such as Hi-Breath Mantle, Warwolf Belt, etc. for the Red Mage
 * Magic Defense and Haste gear is helpful as well for the Red Mage

The Fight


 * Upon entering, have the RDM cast Protect on the melee, and Shell, Stoneskin, Blink, and Refresh on himself. Use the Hi-Breath Mantle if necessary. Rest to full MP.
 * Once MP is full, cast Haste, Baraero, Phalanx, and Refresh. Have all enmity+ gear equipped at this point.
 * Once the Race Runner is spotted, the RDM should use Provoke if subbing WAR, or Stun if subbing DRK. Then immediately use Warcry if subbing WAR or Last Resort if subbing DRK.
 * Have the WAR or other melee engage the Race Runner. Defender might be a good idea to keep from crossing the hate line.
 * Continue to reapply any of the earlier buffs as they wear off, especially Stoneskin and Blink. Continue to use Provoke and Stun as often as possible. Have the melee save TP for a stun based weaponskill incase the Race Runner begins to cast Aeroga III.
 * Hate might be shaky near the end of the fight. Use Warcry, Souleater, Last Resort, Convert + Cure IV, or high enmity debuffs such as blind to keep hate from the melee.
 * While you won't break any time records with this strategy (It usually takes about 10-11 minutes total), it's very consistent if the RDM knows what he's doing. Presumably any other melee would work for this strategy, though obviously it would need slight adjustments in each case.

RDM/NIN and THF/NIN
Jobs RDM/NIN THF/NIN (other melees may work)

Supplies
 * Antidotes for the melee
 * Enmity gear such as Hi-Breath Mantle, Warwolf Belt, etc. for the Red Mage
 * Enmity down gear such as Raven gear for the Thief
 * Magic Defense and INT gear is helpful as well for the Red Mage

The Fight


 * Upon entering, have the RDM cast Protect on the melee, and Shell, Stoneskin, Utsusemi, and Refresh on himself. Use the Hi-Breath Mantle if necessary. Rest to full MP.
 * Once MP is full, cast Haste, Baraero, and Refresh. Have all enmity gear equipped at this point.
 * Once the Race Runner is spotted, the RDM should use Chainspell then repeatedly use any spell you wish to begin building hate. Bind works well and only costs 8 MP per cast.
 * Since you have Utsu you can straight tank this mob. Try to keep it at a reasonable distance so that it does not hit you with melee TP attacks (12' - 14'). If you move outside of 14-15 steps away from Race Runner he will move closer and cause the melee to have to give chase. Also, at this range he will only use his Toxic Spit TP attack and his various spells. This ensures that he does not use his AoE dispel or any of his harmful TP attacks.
 * Have the THF or other melee engage the Race Runner.
 * The melee may pull hate off of you near the beginning of the fight, but Cure IV will immediately pull hate back. Cure IV is your main source of hate build in this fight. Have the melee wait until Chainspell is down before they attack to prevent the melee from pulling hate early on.
 * Continue to reapply any of the earlier buffs as they wear off, especially Stoneskin and Baraero. When Aeroga III goes off recast Utsu and use a Cure IV. This will ensure that the RDM holds hate.
 * Keep both members of the party at full health. If one of you gets hit with Numbing Nose there is a possibility that Race Runner can one shot you (Have seen up to about 1150 dmg from a single Numbing Nose attack).
 * Yet again you won't break any time records with this strategy. Aproximate complete time is around 9-10 minutes with good dmg coming from the melee.

SMN/NIN
Jobs SMN/NIN (solo)

Supplies
 * Antidotes (recommend 5 stacks)
 * Yagudo Drinks (recommend 3)
 * Hi Potions (recommend filling your inventory)
 * Reraise (just one is fine)
 * Shihei

The Fight

Strategy (in order of importance):
 * You'll be kiting clockwise around the large section of open ground, and between the pillar and the wall.
 * Never get close enough for him to hit you with cyclotail.
 * Always always always make sure you have enough room to run away from him if he choses to use Aeroga 3. Even take a couple shots of poison to make sure you have an escape route.
 * Keep shadows up. If he hits you with gravity, you may not be able to escape aeroga 3.
 * As soon as you see "readies poison spit" hit your antidote. You should be able to remove the poison before it does any real damage.
 * Keep yourself alive with hi potions if you've been forced to take some poison damage.
 * Eclipse Bite right after Aero 4 and Gravity
 * Resummon Fenrir if he dies (do this right after gravity, aero 4 or blink)
 * Keep refresh on with yag drinks

The fight is fast and exciting, you'll need to know what's going on at all times in terms of your mp,hp,shadows,refresh,pet status,poison status, what the eft is casting, time remaining, and where the eft is at.
