I've been waiting around with the blue eye orb and darkmoon covenant ring on for about 30 minutes with no invasions (I'm doing the all miracle trophy run and don't want to farm crows for 4 hours for souvenirs), what places are usually active for blue invasions at SL70?
Im on PC and im using the PVP overhaul mod, which added an item that searches for invasions everywhere.
My level 60 darkmoon was getting mostly summoned to the DLC areas.
Use the gold serpent ring, 10 soft humanities, and farm the crows. It took me about an hour last night and I was done
