This mob spawns at -855, -855, -505 which is the second-most-southeast room of the zone where the cliknar caves are, south side of the room.
In the Foundation: Spawns in place of cliknar in the western part of the zone: One known location is just outside the south entrance to the cliknar cave at about -440, 2200.
Went there tonight on CZ-Ro to help a guildie Monk get an earring upgrade. Was rather disappointed to see after spending 4 hours to get the a Master Scout to spawn that while dropping the earring, that it was listed for hybrid and pure casters.
its spawns at master camp which is where a master scout, soldier and master spawn.
in the foundation you get there by hugging you left along the zone in take the first tunnel on your left go straight in (watch some of the burnyai see invis) once you go straight in take the left and you will find an opening and straight from that opening there is a bubble with 2 connection tunnels to it, the camp is the right tunnel good luck if you avoid the SI along the way some of the time when running into that tunnel the 3 burnyai see you which are all place holders to Trag.
once you get to the camp at the opposite direction of the clay golem which is the brass golems ph. all of the cliknars back there by the safe tunnel which looks like an L on the map are all the masters place holders.
also if you know them red gold golem, brass golem, Trag, a flint genati also spawn in that area as well.
