Valâ€™kyr Twins is one of the more interesting fights in the Coliseum especially for healers. The encounter consists of two Valâ€™kyr who share a relatively large health pool (28 million+). This encounter requires relatively decent buff management along with snap DPS switching in order to get through it.
Divide your raid equally in two groups. Split the tanks, DPS, and healers down the line. One group will be on the left, and the other group will be on the right. For the sake of healers, use groups 1 and 2 on the right, groups 3 and 4 on the left. Doesnâ€™t matter which groups. Just have it set in such a way that group positions match group numbers.
How the essences are positioned
Right clicking on the color provides the appropriate essence buff. Your DPS will wish to pick up the buff that is opposite the twin they are engaging. Healers may wish to collect the same colored buff as the twin their DPS is attacking.
Example: The half of the raid that is attacking Fjola Lighbane will be picking up a dark buff. The healers on that side will wish to pick up the light buff.
Each twin has a vortex that will do ~6000 damage per second every 5 seconds. Itâ€™s an 8 second cast. The best way to mitigate it is to gain the same colored buff that matches the twin who is casting the vortex.
Example: Eydis Darkbane is about to case Vortex. The players who are attacking Darkbane should immediately pick up the dark buff to mitigate incoming damage until her channel is finished.
When I did this encounter as DPS, I would stand next to the buff that was opposite the one that I currently had. This way, I could switch easily and DPS the opposite twin.
One twin will cast a shield on themselves. It absorbs ~700000 damage. While their shield is up, they will cast Twinâ€™s Pact. It takes 15 seconds for them to cast that and when it goes off, 20% of their health is restored. The idea here is to have the entire raid switch to the twin who is casting Twinâ€™s Pact and break their shield. A Rogue or a Shaman can then interrupt Twinâ€™s Pact.
Example: Fjola Lightbane just cast Shield of Light and is channeling Twinâ€™s Pact. The DPS attacking Edyis Darkbane will run behind her, pick up the darkness buff, and start opening up on Fjola. MacktheKnife, a Rogue, manages to kick and interrupt Lightbane from healing.
Surge of Darkness and Surge of Light are raid wide â€œaurasâ€ that inflict damage to everyone who is of the opposite buff. Light buffed players take damage from Surge of Darkness and viceversa. Nothing can be done about it.
Periodically throughout the fight, there are going to be balls that come in from all sides. Youâ€™re going to have a dark ball and a light ball. If a ball hits a player who has the same buff as the color of the ball, they will gain a buff. If the ball hits an opposite coloured player, they take damage. The balls will naturally be drawn toward the twins.
If you want some practice for hard mode, have your healers run interference with their colored balls so that the DPS wonâ€™t get hit by them.
Example: Mattâ€™s healing the side thatâ€™s DPSing Darkbane. Mattâ€™s buff is the dark essence. Balls start appearing. Matt starts shield everyone and begins chasing dark balls and running interference so that the light balls can get through and hit the DPS.
Raid groups starting out will want to try their luck with 6 healers before dropping down to 5. Split them down the line. If you have an odd healer, coin toss it or random roll the side for them to go on.
Do not get tunnel vision here. Remember, just because youâ€™re on one side with one buff doesnâ€™t mean you cannot heal the other group if you need to. You can cross heal if one side happens to be struggling for some reason.
How do Discipline Priests heal through the raid-wide tick?
Drop some gold on the Prayer of Healing glyph. That will help soften the blow. Shield spamming 10 different targets helps too if you can keep working the global cooldown.
This is going to require a bit of cooperation from the raid. Try to have your members stand near each other when theyâ€™re not trying to intercept balls. Holy Light splashing helps. If not, stick to beaconing the tank and going on auto heal on everyone in the area.
