Me and a friend did this without the previous steps when one stays in the room and the other goes to the underworld (under map). We only had to do this once when we did this approach. The one on top will kill adds as they come in.
See attached for my submission. The concept is based upon all the events that has placed Neverwinter into ruin, but continues to rebuild and provides the flame of hope to the downtrodden. Thank you;
