I go thim to spawn at +1250, +2193 at a 2 pop point. Just to the south of this spot is an area to camp, is free of roamers and has another potential named pop point to the east (3 spawn) The Collector.
Both of these little camps can be pacify pulled or FD, the crows are a pain cos of the blind. You can either kil them as they fly nearby or just time it right and can get both named to camp without adds.
Ebontail popped twice in a row, only saw The collector once
