Mining

Walls within the 49 tiles (7x7) of a cave entrance cannot be mined. Be careful, as mining without supports may cause a cave-in that can cause HHP and SHP damage and will kill you if you get hit by too many. Mining drains stamina based on the type of the tool used, it's quality and the hardness of the tile relative to a character's mining ability.
