Hole

Hole is an Adventure Map feature that can be located on land tile, that is neither water nor shoreline. They can either be placed on the map by the map-maker, or they appear after a hero has digged the ground. Digging and holes have two purposes. Firstly, digging is typically the only way to find the grail artifact – another possibility is to find a hero with the grail artifact. Secondly, tiles with holes in them cannot be disembarked with a boat. This makes digging holes next to the shoreline in order to prevent enemy heroes' invasions a strategic feature.
