Strategy

As the last boss of the max-level Coilfang Reservoir wing, Kalithresh is an appropriately difficult and time-consuming fight. He is fought in a room lined with tanks, full of some unknown substance. The party must keep up steady damage per second on him, as he has a fairly large amount of health, and he periodically reflects magic. His only other ability of note at this point is a randomly targeted Impale, which does 500 damage every 3 seconds. If he retargets someone before their Impale wears off, it will stack and refresh the duration, so healers must be paying attention.

Every so often he shouts and begins to channel a spell to the closest container near him. At this point, the container becomes targetable, and the party must attack it. Note that the warlord continues attacking while channeling, so the tank will still be taking damage, however, if he is not enraged his damage on any average geared tank will be negligible, so it's recommended everyone in the party starts dealing damage to the container, including the healer. It is imperative that the container be destroyed before he finishes channeling (10 seconds). If he manages to get the spell off, he enrages, increasing his attack speed by 100% and his damage by 75%. This ability will stack if more containers are not destroyed. Since they are only targetable while he's channeling, there's a certain urgency to this fight. As he will use this technique on the container close to him, a good technique to killing the containers quickly is if the tank places the boss next to each container. That way you maximize the time you have the whole group attacking the container.

Mages should cast Amplify Magic on the party beforehand, as all of Kalithresh's attacks are physical damage. Rogues and feral druids should save their energy for a container when the timing for a container is near.
