Something fun you should try

I was having trouble completing the challenge to capture at least 15 beasts in a area for Einhar, most I could get was 12.

So I took the Great Migration atlas passive, juiced a T16 Dunes map, added a winged bestiary scarab, then wham bam 35 packs of Einhar beasts to capture. Not the easy kill mobs but the tough ones.

The entirety of the map was filled and was non-stop fighting. At one time I must have been fighting 8 packs at once.

I'm probably not explaining it very well, but was definitely one of the most enjoyable things I have ever done in PoE.
