The Bestiary of Diablo I was filled with run-of-the-mill terrors like Zombies and Balrogs as well as exotic and unusual foes like the Acid Beast and Cave Vipers. This is a list of all the terrors you will find in the labyrinth beneath the town of Tristram. Monsters are listed by the area they first appear in: monsters might still appear in multiple areas. In addition to the information obtained from the game, a lot of information was uploaded from Jared's guide.
