From Dark and Darker Wiki
-volley orb attack is inside of the wall 75% of the time, which makes it impossible to tell which direction the "cresent moon" orientation is in (obviously try stay in the middle, but come on.. make them like visible through a wall or something) -mist part of the boss is boring -her dash can literally spawn on top of you
definitely a promising, skill required boss, but if you get RNG'd there's no chance for you.
