Digging is the act of applying a [[Tools#Pick-axe|pick-axe]] to a wall with the intention of demolishing the wall to form a passage. How long it takes to dig is dependant dependent on both the player's ASTR (for damage to the wall) and DEX (how many action points it takes for 1 turn of digging.)<br>

Every tick the player strikes the earth for damage equivalent to his ASTR multiplied by the pick-axe's material strength divided by 500. When the wall runs out of HP, it will break and turn into a tunnel for the player to walk through.<br>Destroyed walls also have a small chance to drop a valuable [[stone]].

Every tick (regardless of how long it took) the player consumes 500 nutrition points (see [[Eating#Fullness|Eating]]) and gains some ASTR experience. This rapid consumption of NP will starve the player very quickly over extended periods of digging, therefore it is recommended that you always dig with the strongest pick-axe available and to keep digging to a minimum.
