I found this post while searching for a way to turn the lighting effects down for the bosses. I still want to see the attack indicators; I just want to reduce the cosmetic lighting. As someone with light sensitivity stemming from a medical condition, this is becoming a big issue for my game play. My vision becomes temporarily impaired by the flashes and then I keep dying because I can't see the mechanics. Alexandria is really bad. I dread going into expert roulette but I need it for tombs and gear. I am really hoping someone replies to this with a solution.

BTW...I have already adjusted the character, party, etc. effects. Like Bearskjold indicated, this is about the BOSSES.
