Is there a pattern to Vanaduke's shadow fire tile creation?
Solo'ing FSC is a daily routine to me now, but one thing that may still trouble me is the shadow fire created by Vanaduke's mace smash: debris fall, parts of the floor light up, then shadow fire tiles may appear.
I usually try to move away from the lit floor; but as far as I can tell the location of shadow fire tiles is not really related to lit up parts. Shadow fire tiles may appear there, or may just pop into right where I was running towards.
