| '''21-60''' ||style="text-align:left"| '''Chance to find a creature.''' See below.
If creatures are going to appear in the section, the GM must roll &creature, then check the mine level and the creature type.
* '''Reroll''' If the creature type rolled belongs to the Humans, Halflings, Youkai, Angelics, or Demonics category.
* If mine level is -4 or lessshallower: '''The maximum threat level is 3''' (TL4 and TL5 must be rerolled)* If mine level is -5 to - 14: '''The maximum threat level is 4''' (TL5 must be rerolled)* If mine level is -15+or deeper: '''The maximum threat level is 5''' (no rerolls based on threat level)
=== Ore patch generation ===
Then, the GM checks the current mine level.
* If mine level is -4 or lessshallower: '''All ores are common''': the GM uses '''&ore-c''' to determine ore type.* If mine level is -5 to - 14: '''Ores can be of any rarity''': the GM uses '''&ore''' to determine ore type.* If mine level is -15+or deeper: '''All ores are rare''': the GM uses '''&ore-r''' to determine ore type.
See the [[Mining#How to mine ores|section below]] to understand how mining and extracting ore works.
