From the back of the book
You have in your hand all you need to play the Tunnels and Trolls complete fantasy role-playing game! As a Games Master you direct your friends through the deadly labyrinths that you have designed for their evening's entertainment: this book will give you the framework of how to create complete fantasy characters, use combat and magic with simulated dice rolls. You will be the master of all actions!
The World of Tunnels and Trolls is one where you lead your players through dank dungeons, where there are deadly traps and dire monsters at every turn, where death lurks in cobwebbed vaults alongside undreamt-of treasure, wheer sword clashes with shield, where arcane magic burns the underground air with strange energies.
These are the complete Tunnels and Trolls rules for multi-use adventures and are an expanded version of those found at the end of the Two-in-One adventures
