The Avatar of Below or Brell The Duke of Below can be found inside the Butcherblock Mountains just past the first griffon tower at the start of the zone. He is in a small area near a giant crack in the mountains exact location unknown.

Throughtout the fight Brell will continously call upon two sets of Bugbear adds which can add damage to the raid. They can also cast some impairments on the raid force which are unknown at this time. The first set of adds is a group of 7-9 Bugbears about level 83-85 heroic ^^^ creatures. Brell will also call upon 2-4 level 83-85x2 epic bugbear adds.

At the start of the fight and throughout the fight Brell will also cast an area wide Knockback that can send people flying. This is why you must pull him into an area which will negate the knockback effect. However this problem is the least of the worries since he has a nasty buff that is permanently on him called Miner's Curse.

The Miner's Curse is problematic for the raid force and as a bit of warning this snapshot is from the level 76x4 version not the newer 88x4 version. The damage potential and percentages may have changed on the buff or they could remain the same.

You will want your raid members to have atleast 70% or higher resistance to disease to negate the buff's damage effect.
