Random Dungeon Encounters

Directions: When a random monster encounter is called for, roll a d12. Cross-reference the result with the dungeon level where the encounter occurs on the Monster Sub-table Matrix. Once the sub-table is found, roll a d% to determine the actual monster(s) encountered.

The # column lists the numbers encountered on the dungeon level equivalent to the monster's level. If encountered on a lower or higher level, adjust the numbers encountered as follows:

Lesser monsters encountered on a lower dungeon level should have their numbers increased by the same amount for each dungeon level lower than their monster level. For example, the sub-table# column lists 2d10 for goblins (first level) encountered on the first level of the dungeon. If encountered on the third level of the dungeon, they would be three times as numerous (6d10). The same procedure applies equally to higher level monsters, with the following exceptions:

NPC parties or individuals encountered have their class-level increased rather than their numbers.

Ninth and tenth level monsters usually are encountered with attendants or minions at lower levels in lieu of greater numbers.

Greater monsters encountered on a higher dungeon level will have their numbers decreased by 1 for each dungeon level higher than their monster level (minimum of 1). For example, the sub-table # column calls for 1d8 Shadows on the fourth level of the dungeon. If encountered on the third level, the range would be reduced to 1d8-1. Greater monsters that may normally have minions will have fewer minions or none at all if encountered on a higher dungeon level.
