Got this augment today. Grelik spawns at the bottom of Kaesora Library. You go to the pit side of Kaesora and drop into the pit (you can die if you fall wrong). You then take the halls down to the very bottom of the dungeon where you'll see a platform surrounded by water. On the platform are various Iksar model mobs. In the center of the platform you'll find either our named mob (unlikely) or an Imperial Scourge.
As far as I know, his placeholder is the Imperial Scourge in the center of the platform. You can set up in two areas (or more if you're creative). I used the surrounding ledge (it surrounds the water and the platform) to campfire in my party. While you can't set up a campfire right on the ledge as it's sloped, there is a flat area that works. There are no roamers on this ledge so it's safe to buff and prepare.
I then used group invis and we dropped down. There are two hallways in which you'll find a golem model roamer. The hallway to the (East?) has only that golem, the other hallway has a golem and two Iksar guards. I set up in the hallway with one golem.
We killed the golem. He respawns in approximately 21 or 22 minutes. Basically, when there is 8 minutes left on the last golems corpse, you'll get the next roamer popping. So I arranged that I wasn't pulling or killing when he was about to pop.
Nothing in that area that I ran into saw through invis. There are a few mobs in Kaesora that do see through invis. For example, I ran into a diviner that sees through invis. But so far on the way to this camp, invis has worked fine. We used this for pulling. we would group invis, then our puller would bring the mobs right to our feet and we'd tag whoever stayed behind.
We did this killing the center Imperial Scourge until we got our named. There is another aug dropper in this area. I have yet to kill him. The named hit the 4K AC tank for an average of 1700. We had two healers and for our tank, this was a good thing. It was a fairly straight up fight.
Of the mobs in this area, only the golems can be snared as far I found. They will run. We used Call of Challenge and fast burns and had no real problems. It's not a hard augment to get and it has great AC and nice hit points.
