When an Ambush card is revealed, examine the grid in the top-right corner of the card to see which corner of the Map is shown.

On your Map sheet, attempt to legally draw the Monster Shape without flipping or rotating it.

You try to draw the Monster Shape starting in the corner indicated by the Ambush card, and proceeding along the edge of the Map in the direction indicated by the arrow.

If the Monster Shape cannot legally fit along the outside, then try again one ring closer to the center.

Repeat this process, moving one ring closer to the center each time, until you are able to legally draw the Monster Shape OR confirm that it cannot be legally drawn. If the Shape cannot be legally drawn, disregard the Ambush card.
