Hounds Good To Me

During the fight several pools of orange and purple color will spawn throughout the room. The tanks will have to bring each felhound to the pool that matches their own color in order to get a stack of [spell=253602].

Note that the [spell=253602] stacks get removed if the felhounds come close to each other, so make sure to keep them away from one another.

Once both [npc=126916] and [npc=126915] have 5 stacks you can pop Time Warp, kill the felhounds and you'll get the achievement.

1. Normal Difficulty or higher.

2. Turn on your achievement tracker, the text will turn from Red to White when it is satisfied.

3. I let my pets take the purple boss, while I took the orange boss. Minimal damage.

4. Keep them spaced out the entire fight, they do not get close to each other, ever, or else the stacks fall off.

5. To get Fel Imbuement, you must bring your color boss to their respective pool color. The pools don't spawn on the ground, they spawn in the green fel pools located at the edge of the den area.

6. Bring the Orange boss to the orange pool when it spawns, rinse & repeat until you have all 5 fel stacks on the boss.

7. At the same time order your pet to bring the Purple boss to the purple pool when it spawns, rinse & repeat until you have all 5 fel imbuement stacks on the boss.

8. Once there are 5 stacks of fel imbuement on both the Orange and the Purple bosses, you are good to go. With the achievement satisfied, the text has turned from Red to White.

9. Nuke bosses, and continue to keep them separated.
