Brell's Rest: Don't Fear the Destroyer
Quest giver - Algera Chindlebolt
Requirements - Gnoll Who Your Friends Are, Clash of the Kobolds, and Gnoll With the Punches
Request phrase: investigate
Entry phrase: ready
Algera wants you to go investigate the rumors of this "Destroyer" that the gnolls have been talking about. Start by heading southwest towards the Pellucid Grotto zoneline to find Shorf the Shaman (marked 1 on the map). Chat with him, and he tells you to talk with Zakarf the Assassin who is standing right beside him. Do so and he attacks, hits for under 6k, nothing special. He is snareable and runs at low health.
With Zakarf dispatched we follow his clue to the watery nook, southeastern area of the zone where you find Grothroth (marked 2 on the map). When you hail him he and his cohorts attack. You'll want some cc or a fd puller for this to avoid getting swarmed over. Grothroth hits for just under 8k, rampage, and flurry while the other gnolls in the area top out around 5k. They all seem to run at low health when down to one in camp. Once everything is dead you can loot the Badge of the Destroyer off the priests of undeath.
Head back to the central area to find Garrhuff Gabblepaws (marked 3 on map). Hand him the 3 badges and med up. When you hail him you are beset by a wave of ambushers: 2 gutpiercers, 2 ambushers, and Reurhof Gnawbones. Reurhof hits for around 7500, rampages, and summons, gutpiercers and reavers hit around 7k and don't summon. All are rootable and mezable, so bring some sort of cc. Once those 5 are dead the next wave spawns: 2 gutpiercers, 2 ambushers, and Vark Scrapseater. Vark hits 7500, rampages and summons.
When both waves are dead, head a bit west to find Urkbark Pinchpaw (marked 4 on the map). Hail him to wake him up, then kill him. He hits around 8500, rampages and summons. Once he is dead hail Algera to spawn the chest, lock the instance, and finish the mission. Say "leave" and she will port you out of the instance.
The chest contains one of the following:
