Pain Elemental Evolution Quest

Go to Astral and start the Memory Lane run. Follow the directions until you kill a pain elemental that opens a portal. Enter the portal and proceed through a short maze until you get to the leech area. Kill all of the leeches withing a repop (about 5-10) to spawn the pain essence ticket. Wander around until you find the room called PAIN with a gate in it. Enter the gate and go 2n 3w until a dead end. Enter the door (priv) and give the essence to Scorn. Leave, go east until you hit a dead end and enter the inferno to talk to Hatred. He will open a door for you back towards Scorn's direction. Go to the door and enter for a fairly large fight. Loot the Power and bring it back to Hatred to unlock Pain Elemental evolution.
