To Hell and Back

From Diablo Wiki

The adventuring book for Diablo-flavoured 3rd edition D&D, To Hell and Back's quests and adventures are similar to those in Diablo II. Three hirelings are also introduced - the Rogue, the Desert Mercenary and the Ironwolf. It also contains a great collection of Diablo monsters. It can be played with or without the Diablerie, but for those who want a fuller Diablo flavour should use both.
