Hidden Basketball Court
Proceed through the training section until reaching the courtyard. Fight with the
guard until he retreats, then hit him until he stops. Take the key from the table
and enter the area where the guard originally appeared. Move to the end of the
hall and use the key on the door. Then, enter the door to reach a court
containing a ball and scroll.
Flash Bombs And Undead
Flash bombs not only blind, but damage undead. I
believe two bombs will take them out.
