S4 The Lost Caverns of Tsojcanth - Tsojconth Encounters Comparison

This page details the encounters in the 1976 Tsojconth tourney version of the module with those published in S4 in 1982.

Note that the Tsojconth scenario did not include any wilderness encounters---they were all added after the 1976 tourney was published. The Encounter Numbers and Titles are drawn from S4, since they're more colorful than those from the original tourney (in which most of the rooms were not titled at all).

The maps for the dungeon levels are very similar in both editions; in cases where encounters do not exist in the Tsojconth module, the encounter area is not keyed on the map, and is presumed empty.
