Wilderness Encounters

From OSE SRD

This section provides encounter tables by terrain type, 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.

How to Roll an Encounter

Roll 1d8 and 1d12: 

  • Look up the d8 result on the column in the table below that corresponds to the terrain being explored. The result indicates which sub-table to consult.
  • Look up the d12 result in the sub-table indicated.

Notes

Aerial encounters: Always use the Flyer table, in sub-table 1, opposite.

Lost World: In Lost World or prehistoric settings, any Animal result may be rolled on the Prehistoric Animal table, in sub-table 2, opposite.

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