We'll need to be more organized on Heroic Eonar than we needed to be on Normal. To this end, we will be dividing the raid into sub-groups and we will be sending these sub-groups to various levels to handle different types of adds.
Here's a quick overview of the adds:
Small adds
Small adds have no abilities and move on a set path toward Eonar. They must be CC'd in every possible way. Slows, knock-backs, grips, stuns, and roots all work.
Fel Lords are slow and have high health,
Felguards have normal speed and medium health,
Fel Hounds are fast but have low health, and
bats (Volant Kerapterons) have normal speed and medium health but they fly.
Big Adds
The
Fel-Charged Obfuscator runs on the same set path as the little adds, but
he has a cloak which causes all nearby adds to become untargetable. He needs to be single-targeted down. Adds can also be CC'd so they fall behind the Obfuscator and then targeted and killed. The Obfuscator is the top priority kill target.
The
Fel-Powered Purifiers are only on Heroic Mode. They have a
Purification aura which makes
all nearby adds immune to CC. Tanks should pick up the Purifier and move it away from the small adds. Fel Purifiers also cast
Fel Swipe,
a short-range frontal cleave, at the tank --> tanks face the Purifiers away from other players.
The
Fel-Infused Destructor is the big fel reaver type add. He'll move to a set location and then becomes tankable. He must be tanked (melee let the tanks hit him first). If he is not engaged in melee combat he will cast
Artillery Mode, which launches a rocket at Eonar which does a lot of damage. Artillery Mode must be interrupted.
Kill order: Obfuscators have top priority, followed by the
little adds, then the
Destructors, and lastly the
Purifiers.
Obfuscators --> little adds --> Destructors (big fel reaver types) --> Purifiers.
RAID DIVISIONS
For some of the raid, we'll be fighting all together as a group. However, we will designate two sub-groups which we will pull away to handle particular waves:
*
Ranged group for bats: We'll designate one sub-group of ranged with cleave and multi-DoT abilities, plus a healer, to handle the bats (on the middle platform). This will happen twice during the encounter.
*
Strong AoE group: We'll also have a sub-group with strong AoE, plus a healer, which can be split off to handle a problematic Felguard spawn on the upper level. This will happen once during the encounter.
*
Two halves: We will divide the raid into two halves (minus the ranged group) for the last wave of adds. This wave spawns from two different levels simultaneously (upper and middle). For this wave, the ranged will already be handling bats, so the rest of the raid will split into two groups to handle the upper and middle spawn points, then we will all regroup at Eonar to finish killing off the bats.
HEROIC MODE PORTAL SPAWNS
Red = middle platform
Purple = lower platform
Blue = upper platform
Green = bats (middle platform)
Spawn 1: 0:05. Middle Portal. Felguards and a Destructor. Raid stays together. ALL TOGETHER.
Spawn 2: 0:30. Lower Portal. Felhounds and a Destructor. Whole raid jumps down from middle to lower path. ALL TOGETHER.
Spawn 3: 1:00. Upper Portal. Fel Lords, one Destructor, and one Obfuscator. Whole raid uses Extra Action button and jump pads to get to upper paths. Focus down the Obfuscator, then kill the Fel Lords, then the big Destructor. ALL TOGETHER.
Spawn 4: 1:50. Middle Portal. Felguards and a Purifier. Entire raid travels to the middle platform. Tank the Purifier to the side. Kill the Felguards, then the Purifier. ALL TOGETHER.
Spawn 5: 2:30. Middle Portal. Bats. The group of ranged & multi-DoT DPS and a healer splits off to intercept the bats as they fly past the middle path. RANGED GROUP.
AOE Group heads to the upper portal, while...
Spawn 6: 3:05. Lower Portal. Felguards, one Destructor, and one Purifier. Each tank should take one of the big adds. The rest of the raid kills the Felguards, then the Destructor, then the Purifier. RAID MINUS THE AOE GROUP. Meanwhile...
Spawn 7: 3:15. Upper Portal. Felguards. The small group of strong AoEers intercepts and damages these adds. AOE GROUP.
Spawn 8: 3:40. Middle Portal. Felguards, Fel Lords, Felhounds, and one Purifier and one Obfuscator. The raid should regroup on the middle path. Tank pulls away the Purifier. Raid focuses down the Obfuscator, then the small adds, then the Purifier. ALL TOGETHER.
Spawn 9: 4:35. Middle Portal. Bats. The group of ranged & multi-DoT DPS and a healer splits off to intercept the bats as they fly past the middle path. RANGED GROUP.
Spawn 10: 5:15. Upper Portal. Fel Lords and a Destructor. Half the raid fights off the adds at the upper portal. Once these adds are dead, head straight to Eonar to kill off remaining bats. HALF THE RAID (minus the ranged)
Spawn 11: 5:15. Middle Portal. Fel Lords and a Destructor. The other half of the raid fights off the adds at the middle portal. Once the adds are dead, head straight to Eonar to kill off any remaining bats. HALF THE RAID (minus the ranged)
Spawn 12: 5:20. Lower Portal. One Obfuscator. Ignore this add because the fight should be over by the time it reaches Eonar.
Note: I got this portal order from Wowhead. There is a contradiction in their last wave which I believe I have rectified. I am trying to verify the portal spawn order & add waves, as different guides have different portal orders. If you know of a totally accurate guide please post it below and I'll fix this one.
It also appears that many guides lump some of these waves together. Here's a different visualization:
