Festergut Strat

Festergut is estimated to have 43.23 million HP.

ENVIRONMENT, POSITIONING, AND PULL:
(1) Festergut's room is circular and has one entrance, which becomes gated once the encounter starts. It is a mirror image of Rotface's room.
(2) Only 1 tank is needed on this fight, though there is a possibility for 2 (see Unconfirmed Gastric Bloat).
(3) Main tank runs in and places Festergut in the center of the room. Melee DPS take their customary position behind the boss. Ranged and healers make a semi-circle around the boss, ensuring that they are 8 YARDS APART. This will reduce the chance of multiple people being hit with a single Vile Gas.
(4) This fight is a straight-up DPS burn with a short enrage and few mechanics. The final enrage timer is yet unknown. At its lowest, I've seen a 5 min hard enrage and the longest was over 7 min.



BOSS/ENVIRONMENT ABILITIES:

Proper positioning makes perfect!

GASEOUS BLIGHT
Inflicts shadow damage to the entire raid every 2 seconds.
0 Inhales: 4,388 to 4,612 per 2sec
1 Inhales: 2,925 to 3,075 per 2sec
2 Inhales: 1,950 to 2,050 per 2sec
3 Inhales: 1,463 to 1,537 per 2sec
At the start of the encounter, the room will be flooded with a Gaseous Blight which will deal damage at the 0 Inhale level. After every inhale, the amount of damage is decreased.

VILE GAS
-Instant Cast. 8 yard radius. Frequency unknown, but approximately 20-30 seconds.
-Inflicts a Vile Plague in targeted area, inflicting 4,875 to 5,125 (3,900 to 4,100: 10man) Shadow Damage every 2 seconds for 6 seconds. The plague causes the infected targets to vomit uncontrollably (Disorient) inflicting 3.9k to 4.1k damage to nearby allies.
-This is the reason why range must be spread out in 8-10 yard intervals. You do not want multiple raiders puking on each other.

GASTRIC BLOAT
-Instant Cast. 1.7 minute duration. Unknown Frequency. Stacks up to 10.
-Inflicts 14625 to 15375 damage and applies Gastric Bloat to the target, increasing damage done by 10% for 1.7 min and will cause a Gastric Explosion at 10 stacks inflicting massive damage to nearby allies.
This is an unconfirmed ability because I have yet to observe it or see a PTR capture executing a tank switch. Presumably, this will be applied to the tank at an unknown frequency causing an instant death explosion at 10stacks. Therefore, the tanks must switch at some point to prevent this. Without knowing the frequency of the application, however, I cannot provide further strategy.

INHALED BLIGHT
-3.5 second cast. Unknown frequency, but approximately every 30 seconds.
-Inhaling the Gaseous Blight increases damage dealt by 30% and attack speed by 30%.
-As the damage of Gaseous Blight decreases, Festergut's damage increases. Festergut will inhale the blight 3 times, gaining a total of 90% damage and attack speed during the 3rd Inhale duration. It is advisable to use DR CDs during this time as the tank will be taking massive damage. Approximately 30 seconds after the 3rd Inhaled Blight, Festergut will cast Pungent Blight.

PUNGENT BLIGHT
-3 second cast. 20 seconds after Inhaled Blight.
-Violently releases the Gaseous Blight, dealing 48,750 to 51,250 (42,900 to 45,100: 10man) Shadow damage to all enemy players, releasing the deadly Blight back into the room. Resets the stacks of Inoculated.
-Everyone gets hit by this. Fortunately, there is a mechanic to reduce the damage through Inoculated.

GAS SPORE
-Instant Cast. 12 second duration. 35 second frequency. 5 targets.
-You have the Gas Spore! You will explode and infect all friendly players in an 8 yard radius with Blighted Spores, dealing 1950 to 2050 Shadow damage and increasing their resistance to the Blight. Players who survive Blighted Spores will become Inoculated.
-Five random raid members will be infected with Gas Spores, signified by a Loatheb-esque "spore" above their head. When this occurs, everyone not infected must stand next to the closest player within 12 seconds. After this time, the Gas Spore will erupt and infect everyone within an 8 yard radius with Blighted Spores.

BLIGHTED SPORES
-Instant Cast. 6 second duration. 8y ard radius upon removal of Gas Spore from infected players.
-Inflicts 1950 to 2050 Shadow damage every 1 sec for 6 sec.
-This can stack up to 5 times if you are in range of 5 Gas Spore infected players, which should never occur. After you receive Blighted Spores, you must return to your original position to avoid multiple people being hit with Vile Gas. When the six second duration is over you will become...

INNOCULATED
-Instant Cast. 2 minute duration. Stacks up to 3 times.
-You have become resistant to the blight, decreasing Shadow damage taken by 25% for 2 min. Stacks up to 3 times.
Each instance of Inoculated will reduce Shadow damage by 25% up to 75%. This mechanic allows your raid to survive Pungent Blight. Before each Pungent Blight cast, all raid members must have a 3 stack.

After you have been hit with Pungent Blight, rinse and repeat the strat until the boss is dead.



IMPORTANT NOTES:
1. The key to this fight is heavy DPS and getting everyone x3 stacks of Inoculated before Pungent Blast.
2. Make sure the tank is in range to get hit with Blighted Spores from a Gas Spore infected player. If not, he will die to Pungent Blast. Best bet is to have the melee infected player move directly under the boss, as Festergut's hit box is very small.
3. If by the off chance that a melee player is not hit with Gas Spore, have one ranged player run to the center of the boss to hit both the melee and the tank.
4. RANGED & HEALERS STAY SPREAD OUT! 8-10yd range. You do not want multiple people hit with Vile Gas.
5. GET BACK TO ORIGINAL POSITIONS AFTER YOU HAVE RECEIVED BLIGHTED SPORES! See (4).
6. If the enrage timer remains at 5min, then it is recommended to ignore all spores after the second Pungent Blight. He will not have time to cast another one before his enrage.
7. Use DR/Avoidance CDs during the 3rd Inhale period. Your tank will be taking massive damage during this time.


As always, this strat is subject to change.
