5. Create Encounter Tables

When designing a wilderness area, one touch that will really set it apart is a custom encounter table. Choose those monsters that seem most appropriate to the area, using the standard encounter tables as a guide. If you have placed humanoid lairs or encampments, you may wish to include their patrols on the custom table. Another alternative is to roll six or eight or ten random encounters using the "generic" encounter table for the relevant terrain type, and use that list as your random encounter table for the area. When doing this, you probably should re-roll duplicates.
