Cruel Slayers are found in all floors of the Echoing Library. Normally they will not move, serving as roadblocks to the player; however, if you are spotted by a Silent Killer it will sound an alarm which activates this monster. Once activated it will relentlessly pursue you, moving at twice the normal steps per turn. Great caution must be taken, as up to three of these may be found in any one room.
