The timing is really quite hard. Farming here is a lot harder than for example griffons. It's guess it's as hard as soloing FoW.
The drops are quite nice. I farmed half a day and got ~90platin. The nice thing is, because the mobs are lvl 24 they drop like 110g compared to the 70g that griffons do. I usually get like 2 purple items a run.
I tried out a few things yesterday and found a set of skills that's a lot safer. I tested a few zealot fire builds as well, but I find them a bit slow.
With these skills one run is about 2:50min.

Glad you like the video

Skills, attribute levels and weapons can all be seen in the video.
Or just look above for an improved version.

If you just want some easy money kill those griffons.
For me it was more about the farming challenge to be able to farm these mobs.
