The quality of the tile is randomly generated between 20-100ql this does not change, but every time you mine, the quality of the shards is randomly generated based on the tile quality.<br>
See [[Prospecting]] for more details on the tile output.
For example, if the tile is generated as 47ql, every time you mine you will get a shards that is between 1-47ql. Assuming you have enough [[mining]] skill.<br>
If you get a message that the cave shudders, it is because there is something behind that tile that prevents you from continuing to mine, for example, a [[Dirt Tile|dirt tile]].
