Lineage of Power

I just soloed this achievement in normal mode on a 120 protection warrior. If I can do it, any class should be able to do it as long as they can sustain the damage from the encounter. I took almost no damage, so I don't expect it would be a stumbling block for any other class/spec at 120.

1. You'll want to push the boss to the intermission, and then run to the blue circle for the [npc=78121] that spawns closer to the boss (to the right if you're looking at the mages from the center of the room).

2. Using the circle at the [npc=78121]'s feet as a guide, you want to stand in or near the edge of the mage's melee range and watch his cast bar.

3. When he finishes a cast, run towards the cloud under the boss. The [npc=78121] should take one or more steps in your direction if you time it right. Once you have the timing right, just repeat for as many cast intervals as you can until he's in the cloud.

4. Once he's in the cloud, be careful not to drag him out of it until the intermission is over. Kill the other adds including the other [npc=78121].

5. When the intermission is over, check that he has the buff and begin moving him to the area for the second cloud BEFORE you deal any damage to the boss. It's a lot easier to get him into place if you don't have to worry about the intermission time window and adds.

6. Once he's in place, DPS the boss until the final intermission starts. Kill the adds that spawn, being careful not to kill the boss or the one [npc=78121] you've been dragging around. When the intermission ends, check that the [npc=78121] has both buffs (Fortification and Replication) before killing him. Once he's dead, you can finish the boss.

Notes: I had a pretty healthy buffer of time to do this despite not getting the timing right for several casts. The [npc=78121] also casts [spell=157801] which is really annoying but should allow you to keep moving the mage if you're careful with the timing. It's a magic effect and snare, so use any abilities you have to dispel it. I used [spell=107574] once during each intermission. You can move to the spawn location for the [npc=78121] before the first intermission, but the delay between the start of the intermission and the mage's spawn should be long enough that most people shouldn't have to worry about this.

I hope this helps! Good luck!

In order to empower each add you have to drag them to the purple mist spawned when Mar'gok channels during each intermission. Knock backs don't work and it's hard to effectively move the mob without a Death Knight Grip. We only had one Death Knight so he talented into [spell=108199] so he could move the Gorian Warmage three times (2x Death Grip, 1 Gorefiend's) in one intermission. The Warmage did not seem to regain health after receiving the Replication buff after the Fortification Phase so we had our boomkin dps the Warmage to lower health while our Death Knight gripped him over to the new intermission location. As soon as Mar'gok went up and the Warmage received the replicating buff we killed the add and the achievement progress turned from red to white. You just have to finish off the boss then you will get the achievement.

Keep in mind, players will still become fixated through the Fortification phase by the Warmage so make sure the fixates run out of the group!

Here is short video guide (2 mins): http://youtu.be/Z28Gv538nAI

1) Keep 1 Warmage from intermission phase
2) Death Grip this Warmage under the Imperator's purple mist
3) Death Grip him under the next Imperator's intermission location and keep him on low hp
4) Kill Warmage after he gets empower from white mist.

Ps: +1 heal will make it much easier.
