Carve on floor. The first monster to move onto the square becomes deeply confused. Zargon rolls 1D4 to determine its direction (1=North, 2=East, 3=South, 4=West) and it moves as far as its normal movement allows in that direction, stopping at a wall or figure. It may still attack any Hero it ends up adjacent to. The glyph lasts 1D4+1 turns or until triggered.
