Hello all I wanted to post the link to my Helm's Hold node map, I do not recommend farming this area as a go to spot due to the aggro and mob placement. However if your just questing or leveling in the area and are looking to pick up some extra astral diamonds on the way I figured I would share it here. The map is at the start of the video, the end of the video is just the last quest line boss fight in the zone.
