Hey everybody, haven't contributed in awhile, searched and found nothing so here we go...
While attempting Halls of Reflection for the first time today, I noticed while being feared by Falric, you can avoid running all over the place by simply standing on the skull altar before the fear is casted.
Defiling Horror - Inflicts 4,000 Shadow damage every 1 second for 4 seconds, and sends all players fleeing in horror. Falric will not attack while the Horror lasts
Simple and handy, works like a charm.
