To do this my way you need a mage and chanter.
Run the mage off the zone in platform and go left along the wall until you hit the blue werewolves. Pull them all with tank. Zerg! AE mez. Destroy!
As soon as you kill your tenth mob run your mage along the wall, past the wreckage and to the right side of the underground entrance there, then up the hill to stand directly under that extended metal platform there on the ledge path. (You can also run up the hill just before this platform on the left side and get on the path there...they will path along there to you but its hard to get the mage there in time to COH before they walk through. /target climber - then pet attack chanter pet, all 8 will come. (I make hotkeys for the chanter, socials, and label them climber, another infiltrator and one howler, ie /target climber. I also put next to them on the bar pet attack and a regroup button.)
As soon as number 8 is dead you can jump off and land in front of the entry to the tunnel and coh as the infiltrators will start coming off the wall and one by one run into your group. Plow away! Once all are deaded, Immediately run left again to the landing platform (which also sticks out) and up to the right side onto the ledge that is level with this platform, run down that path until you are not to close to the landing platform (the normal residents tend to aggro with the aoe stuff most tanks cast so the 10 on your extended target list can multiply to 16 easily but with a chanter its no probs)...the mobs path through here. Will auto aggro. Will get all ten. Dont worry, they hit you with their purses during this whole thing. Once done, you probably need some mana. This is a good place to chill for a minute if you do.
Next head to the opening to the left further down along the wall. I recommend you install Brewall's map http://
www.eqmaps.info/wp-content/uploads/2019/03/gnomemtn.zip for this phase. Pull up the map and you can see where the howlers are, not that you cant just zerg kill everything but that takes time meh...move to the howlers proximity and /target howler on your chanter and send in the pet and hit regroup once mob is on target window (same with earlier). Move down as needed on the paths on map. Without the map, getting to know this area can be aggravating and time consuming. Also, the rare namer that can spawn is in the howler area outside the wall here.
Once you box this 3 or 4 times it's super easy!
All these mobs hit like gimps, nothing like TBL mobs. They also have very little hps. Fun trip and 3 pieces of loot each run, with a short lockout timer! GOOD LUCK!
