Dungeon Encounters

From OSE SRD

This section provides encounter tables by dungeon level, using the monsters found in this book. Referees who are using additional (or alternative) monsters should either adapt the tables to include these, or should create their own encounter tables. Special tables may also be created to reflect the different balance of monsters inhabiting a specific dungeon.

How to Roll an Encounter

Roll 1d20 and look up the result on the column in the table below that corresponds to the dungeon level being explored. The result indicates the monster encountered, with the number appearing in parentheses.

Notes

NPC adventurers: Encounters with NPC adventuring parties are listed in the tables as “Basic Adventurers” or “Expert Adventurers”. Guidelines for generating NPC adventurers can be found under Adventuring Parties, p76.

Number appearing: The values listed in the tables for some monsters do not match the values listed in the monster description. If desired, the referee may use the number appearing value listed in the monster description, for consistency.
