2) Activate your mining pick and stand at the intersection of the four tiles (point E), click the ground, and select the mining action. Be sure that you do not select tunneling. Tunneling will eventually create a mine entrance, which we do not want (at least not yet).
3) Randomly, with a variable chance based on skill, you may drop the rock level at the point where you are mining by 1 dirt and produce a [[rock stone shards|stone shard]]. This is not cumulative. Sometimes you will drop the rock level very quickly for a short spurt, other times you might mine for along time not drop the level. In other words, many failures in a row does not make future success more likely. For each action, the chance to lower the rock is 20% at no skill and scales up with skill, to a maximum of 50% at 100 skill.
4) Attempting to lower surface rock below the ceiling of a mine below results in the message "The rock sounds hollow, you will need to tunnel to continue". At this point, you cannot lower the surface rock any further.
== Notes ==
* Surface mining will produce [[rock stone shards]] on each action that lowered the corner.
* The maximum depth a rock tile may be mined to beneath water is -24 dirts below water level.
* Slopes created with surface mining are limited to 3x mining skill on PvE and 1x mining skill on PvP. Be careful as its possible to surface mine a slope's steepness one mine action beyond what your skill will allow. This small mistake prevents any mining actions on top of the slope.
