Diablo 3 RoS - Ebenezer Samuel Unique Monster - Post Patch
When I finally got him I used the quest, Rumford at the Gate as my starting point and would clear all of Old Tristram Road up to the Old Ruins.
I did numerous runs on Torment levels 2 to 5 on various quests, some using the Old Ruins waypoint.
It took quite some time before I finally got him so don't give up!
I was playing Hardcore Torment V on the PS4
