− | | ??? | + | | The base mine level. When a container can drop a weapon based on field 10, there are two chances for a weapon to be chosen as a possible drop: (a) if its base mine level is closest to the current mine level, or (b) based on a probability equal to a [[wikipedia:Gaussian function|Gaussian function]] defined by the formula <code>e<sup>(-(current mine level - base mine level)<sup>2</sup> / (2 * 12<sup>2</sup>))</sup></code>. A match from the eligible weapons is then chosen randomly to drop. |
