Maybe a mechanic similar to the abyss in croatas end and when you are in the safe zone for that short amount of time the whole arena is lit up??? Or even scrap the safe zone. Survive the darkness and woe of darkness and when you activate 2 of 3 beacons it lights the whole arena for a few secs to unload on the boss thrall or something similar?[spoiler]Captain Insano shows no mercy[spoiler]
