Well, I was playing a game of monstrum (Having meeting the brute and the hunter, excepting one of them) I walked around a bit, collecting stuff and walking around. as I walked around a lit area 6, The lights started flickering. I thought this was a thing that happens, then BOOM! I saw the fiend's little purple field. He saw me, I ran down stairs, than he shocked me. I thought I was for sure Dead, but he is really slow. I outran him. Of course he cutted me later, ending my life like a twig.
And that's why you should run/hide if the lights flicker
Just move back and forth between areas of the ship and run away if you see lights flickering in the distance. If they flicker on top of you then hide until they go. If you keep moving between different ends of the ship you'll encounter him a lot less and you'll have more time to search.
