Mogu Shan Vaults: Elegon (10)

msv_005

Elegon is the toughest fight in Mogu Shan Vaults and in my opinion should have been the end boss. 
This is a 3 phase fight, each phase repeats twice throughout the fight and you fight Elegon in a circular room with an Inner Ring and an Outer Ring.
The Inner Ring is covered by a floor made of energy. Any raid member that stands in this area receives two debuffs, one that increases damage done and healing received by 50% and the other, Overcharged, increases damage taken by 5% per stack, up to a maximum of 20 stacks. A new stack is applied every 5 seconds. Leaving the Inner Ring immediately removes the Overcharged debuff.
Phase One lasts from 100% to 85% of Elegon’s health. Elegon is located in the center of the Inner Ring, and he is stationary. He can be turned, but he does not move from his position.
Elegon does a frontal cone AoE attack every 20 seconds. He also summons a Celestial Protector (every 35 econds) who melees its main aggro target and regularly attacks a random raid member and applies a debuff which reduces the healing taken by that target by 50% for 20 seconds, and MUST be dispelled. When the Celestial Protector is outside the Inner Ring and has over 25% health, he takes 90% reduced damage. At 25% health the Celestial Protector deals a small amount of damage to all raid members every second until he dies upon death he deals a large amount of damage to all raid members and should therefore be killed in the Outer Ring as he also gets the 50% damage buff.
Phase Two starts as Phase One ends and lasts until the adds that the boss repeatedly spawns are not all killed in a given amount of time. The time frame for killing each wave of adds is shorter each time, generally it lasts 40 seconds.
Phase Three starts as Phase Two ends and the floor disappears (fail and you will fall to your death). Phase three lasts until the all of the objects the boss spawns during phase Three are dead. The raid takes increasing raid damage that will lead to a wipe and should not last beyond 80 seconds.
Phase One starts for a second time when Elegon reaches 50% health, and the cycle repeats.
Once the second cycle ends, Elegon will no longer wipe the raid but will stay at Phase 1 and deal massive raid wide damage.
Because of the high DPS requirement it needs to be 2 healed.

Strategy Phase One

Have Elegon tanked facing away from the raid, so that he does not hit anyone except the tank with AoE conal attack. The OT should pick up the Celestial Protectors, and tank them on the edge of the Inner Ring until they hit 24%. Make sure no one is low on health when the Celestial Protector dies (a good time for a tank swap too). 
  • Everyone (including the tank) needs to leave the Inner Ring to reset their stacks of Overcharged (10 is time to panic). The tanks will need to switch tanking Elegon.
  • Healers must be quick to dispel Closed Circuit from players.
  • Ranged DPS and healers should stack up close to the edge of the Inner Ring, so that they can reset their Overcharged debuff easily.
  • The melee DPS and any healers who prefer melee range will simply stack up behind Elegon.
  • There is no reason for the ranged DPS and healer group to move from their location.

Improving Raid DPS in Phase 1

Getting Elegon to Phase Two (85% health) with as few Celestial Protector spawns as possible (preferably 2) needs some tricks melee DPS can stay in, and not reset Overcharged for the first Celestia Protector but will need to use defensive cooldowns to survive. 
Ranged can find a sweet spot at the edge of the border between the Inner and Outer Rings, so a simple jump will reset the debuffs and you can try to find one even before the fight starts. Simply stand as close to the Outer Ring as you can, while still benefiting from Touch of the Titans, and see if jumping in that location resets your stacks of Overcharged.
You should be able to push Elegon to phase Two without the use of major cooldowns.

Strategy Phase Two

This is a DPS burn phase, but there is some raid damage to consider.
When Elegon reaches 85% health, he cast Draw Power for 15 seconds after which he gains a debuff (that increases the damage he takes by 10% per stack which persists until the end of the fight) and will spawn 6 Energy Charge adds around him, these adds will begin moving towards 6 fixed points at the edge of the Inner Ring and must be killed within 15 seconds. 
  • If all the adds are killed before they reach their destination, he will gain a new stack of the Draw Power debuff and spawn another set of 6 adds that move faster so they must be killed with 12 seconds, seconds. 
  • If all the adds are killed before they reach their destination, he will gain a new stack of the Draw Power debuff and spawn another set of 6 adds that move faster so they must be killed with 10 seconds.
  • If all the adds are killed before they reach their destination, he will gain a new stack of the Draw Power debuff and spawn another set of 6 adds that move faster so they must be killed with 8 seconds.

This process continues, with the casts of Focus Power being shorter and shorter, until one or more Energy Charges reach their destination.

When at least one Energy Charge reaches its destination, the boss will enter phase Three and you will have about 20 seconds before the floor of the Inner Ring disappears.
While Elegon casts Daraw Power hit him hard especially on the first cast as this takes 15 seconds. 
Kill as many waves of Energy Charges as possible, when they spawn they can be AoE’d, they have 500K health. Assign specific groups of DPS players for each add. But you will know how many waves your raid can kill it is a waste of DPS to half kill a wave so if you can’t kill a wave ignore it completely and DPS Elegon. The number of waves will depend on your raid’s DPS, but most raids ignoe the fourth or fifth waves.
Ranged DPS and healers, should spend their time at the outer edge of the Inner Ring and simply side-step or jump to reset their debuff of Overcharged. Melee DPS players should quickly step outside the Inner Ring whenever they finish killing an Energy Charge or be prepared to use defensive or self-healing cooldowns to survive the next wave of explosions.

Strategy Phase Three

When one or more Energy Charges reach their destination, phase Three begins.
Run to the Outer Ring and after about 20 seconds, 6 pylons, Empyreal Focuses, will appear around the inner edge of the Outer Ring that are stationary, killable adds that deal no damage. Phase Three ends when all 6 pylons are killed. You need to put a tank, healer and 3 DPS on each side of the room and each group kills the pylons on their side of the room, avoid the ground AoE and don’t run through the walls of fire!
Tanks will have to pick up and tank the Cosmic Sparks, while healers must heal the damage from Elegon and the Cosmic Sparks.
When the phase is over, your raid can AoE the Cosmic Sparks.

Round 2!

When phase Three ends, phase One will restart and will end when Elegon reaches 50% health, instead of 85%.
When Round 2, Phase 3 ends, Elegon gains a buff called Radiating Energies, which periodically deals raid-wide damage to all players, in both the Inner and Outer Rings. The damage in the Outer Ring is considerably higher than that in the Inner Ring. Aside from this, Elegon will simply melee the tank and cast Celestial Breath.
This is a burn phase, when the boss will be taking increased damage from all the stacks of Draw Power that he should have by now (hopefully 8-10 stacks!). Your raid will have a limited amount of time before Elegon enrages (9mins 30secs). 
Everyone should stack on Elegon, heal through the damage, DO NOT reset stacks of Overcharged. Heroism and cooldowns should be blown now.
