Overgrowth
Labyrinth of Ruin includes a new feature called overgrowth. Overgrowth are set up similar to doors in a quest and are shown as green doors in the Labyrinth of Ruin Quest Guide. Figures cannot trace line of sight through overgrowth.
Even though adjacent spaces separated by overgrowth are still considered to be adjacent, figures cannot attack through overgrowth. However, figures can move through overgrowth. In addition, when counting spaces for an ability, players can count spaces through overgrowth. Large monsters cannot occupy two spaces that are separated by overgrowth.
A figure may perform an open or close a door action to remove one adjacent overgrowth from the map and return it to the game box. When a figure does this, it is considered to be opening a door.
