Sacred Haven of Debauchery

What kind of Barbarian are you talking about?

Here is the Diablo 1 knowledge base, and the Barbarian is here. He and the Bard are kind of secret characters, unlocked by editing the ini file. They were supposed to be in the game, but were cut during the beta stage because they were unbalanced. The Monk is also unbalanced, but not to the same extent. Nevertheless, in many pirated versions, the Bard is present, and if not, it's very easy to add him and the Barbarian back. By the way, it was in the first Diablo, and later in Hellfire, that they wanted to introduce a Blood Mage, but they didn't have time, and as a result, this idea was only implemented in War3TFT.
