Well i dont really know how to describe where I am, I went to this house at the beginning which was on fire and a guy with a skull mask on sent me to some underworld place or something and I got a mask and come back to the church as people need saving, the first couple of baddies are easy to kill, but then a "shadow baddie" appears and just sits there doing a move in the same spot.

The game says to press "Shift L" (Left Shift? or Shift + L?) this does a roll but thats all. I can jump behind the guy and hit him all day but he has infinite health. What am I supposed to do here?
