Encounter

Moroes stands with 4 of 6 randomly selected undead. Any combination of these four undead will fight alongside Moroes when your raid starts the encounter:

Moroes will spawn with 4 out of 6 possible adds:

Baron Rafe Dreuger – Retribution Paladin
Lady Keira Berrybuck – Holy Paladin
Baroness Dorothea Milstipe – Shadow Priest
Lady Catriona Von’Indi – Holy Priest
Lord Robin Daris – Mortal Strike Warrior
Lord Crispin Ference – Sword n’ Board Warrior

Crowd control makes this encounter vastly easier as you can potentially have a rough fight on your hands.
Depending on your raid’s priest count you may be able to shackle one or two adds.
I suggest shackling any melee adds before casters with emphasis on the Mortal Strike Warriors.
The only exception is the Retribution Paladin.
If his Shackle breaks he will immediately stun a priest and that’s never good.
Either way you’ll want to have three forms of crowd control for this fight, be it hunters or priests or perhaps even stun locking rogue.

The fight starts as our main tank and off tank pulls Moroes away from the rest of the group.
They will continue to tank Moroes alone until all but one of the adds are eliminated.

Kill precedence is huge as we kill the adds.
Always take out the casters first then move on to a paladin and finally warriors.
You’ll want to leave one add shackled at all times and the hunters will play a very important role because they’ll need to frost trap throughout the fight for added crowd control.
When only one add still stands shackled, the group focuses on DPS while the hunter and priest chain shackle and frost trap the remaining add.
If keeping one up is not working for your group’s composition, it may be better to simply eliminate all four adds before working on Moroes.

At this point the fight becomes much, more simple because Moroes is relatively easy to control.
Moroes frequently vanishes throughout the fight and to combat that we’ll want our Warriors and melee DPS to stand still.

The nasty part about Moroes is when he vanishes, he Garrote’s someone.
Garrote is a bleed that is not dispellable and will last for 5 minutes or until Moroes dies. There are a few tricks for certain classes to get out of the Garotte.
Paladins can bubble, Dwarves can go to stoneform, Shaman’s can self rez, Mages can Ice Block and Warriors can intervene the priests to lessen the chance of a priest getting Garotted.
Garotte is also a good time for a druid tank to innervate another team member or for group member’s to bandage each other.

At 30% health Moroes will enrage, boosting his DPS.
Do not falter, keep up the pace, and remember to continue crowd controlling the final add (if you have one).
If we keep up with our roles when Moroes dies we just have his 4th add to deal with.

Tips

The kill order should be established before the pull.
Since the adds with Moroes are randomly selected, each encounter and dynamic can be drastically different.

Have a hunter or another ranged class do the initial pull.
The hunters should use the pull as a means to lure an add to their frost trap.
Make sure the Main Tank is very safe and secure when the pull occurs because you’ll need Moroes isolated from the rest of the group.
