Each week Arcane Brilliance conjures a portal into the darkest regions of your soul. You should tip Arcane Brilliance, though....those reagents cost money, guys. Also, your soul has a lot of dark regions, so finding the darkest ones is actually kind of a pain. Seriously, tip. Arcane Brilliance took time out of its day to come over and open that portal for you--time that could have been spent killing Warlocks.
