A Web Enhancement for Monster Manual III
A SHORT ADVENTURE FOR FOUR 8TH-LEVEL PLAYER CHARACTERS
You (the DM) need the D&D core rulebooks-the Player’s Handbook, the Dungeon Master’s Guide, and the Monster Manual-as well as Monster Manual III to run this adventure. This scenario utilizes the D&D v.3.5 rules.
To get started, print out the adventure, including the map. Read through the scenario at least once to familiarize yourself with the situation, threats, and major NPCs (particularly their motivations). Then review the information on the trolls and mindshredder in Monster Manual III. Text that appears in shaded boxes is player information that you can read aloud or paraphrase for the players at the proper times. Monster and NPC statistics are provided with each encounter in abbreviated form or, where appropriate, the proper page in the Monster Manual or Monster Manual III is referenced.
