Got the Aetherials and the Chlithonions at Nemesis a couple of days ago, have not found any Nemesis bosses yet. Keep looking in their “territories” - any hints as to how to find them???
Good info here, thanks! Still have not found one though! I will keep looking…
Finally! Found the Aetherial Nemesis in the area right before the lab in act 1.
Loot was underwelming though! I’ll keep trying.
