This section provides encounter tables by terrain type. Referees who are using additional (or alternative) monsters should either adapt the tables to include these or create their encounter tables.
Roll 1d8 and 1d12 :
Look up the d8 result on the column in the table below corresponding to the explored terrain. The result indicates which sub-table to consult. Look up the d12 result in the sub-table indicated. Aerial encounters: Always use the Flyer table in sub-table 1.
Lost World: In Lost World or prehistoric settings, any Animal result may be rolled on the Prehistoric Animal
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 .
