If you're daring and/or can do enough damage in a short period of time, you can take on the other side as well. If you can handle the quick respawn and you can manage not to fall off, it seems like a fairly decent place to do farming without going further away. I've had periods where I picked up 10 cloths in about 2 minutes, and also went about 5 minutes with only like 4-5 cloths. The embersilk drops 1-2 at a time, up to 45 silver per kill.
If you can manage to pick 'em off slowly, it's pretty much a consistant flow of respawns (I wanna say they respawn in a minute, if not shorter). In the northwest part of that little pillar, there's a group of 5 of them.
Only problem is that they're close together and they'll likely come at you in a big group. There are quite a bit of them and seem to spawn very quickly.
