Mining
Description
Mining is a skill gained by creating caves. Higher mining skill can get you higher quality Rock Shards or ore. Mining skill affects body strength.
Method
Mining is primarily done in caves. Activate a Pickaxe and right-click a rocktile, then select Mining -> Mine. Every mining action on a regular rock tile gives a rock shard. +/- 25 mining actions creates a cave entrance. Within a cave, +/- 50 mining actions are required to continue the tunnel.
To find specific ores, you should prospect on the surface. Prospecting in the cave itself will only tell you the quality of the tile (assuming you have at least 20 prospecting skill).
Reinforcing cave walls
You can reinforce cave walls by adding a Support Beam to it. You cannot mine a reinforced tile, but it will prevent cave collapse.
Multiple tunnels
This is a reminder that the Wurm world is a 2D world and that all tiles are pillars. you can mine up and down but you can't make a tunnel above or below another tunnel. it is possible but it will make a big hole between the tunnels.
