Diablo + Hellfire (1997)

Diablo (otherwise known as Diablo I) is an action role-playing game developed by Blizzard North and released by Blizzard Entertainment on December 31st, 1996.

Set in the kingdom of Khanduras that is located in the world of Sanctuary, Diablo has the player take control of a lone hero or heroine starting outside of their house in town as they set out on a journey to rid the town of Tristram of the titular Lord of Terror, and his horde of demon minions lurking in the shadows within the Dungeon lying underground, beneath the Cathedral located on the outskirts of town.

Diablo was a best seller. Following its popularity, an unofficial expansion pack entitled Diablo: Hellfire was developed by Synergistic Software and released in November, 1997 by Sierra Entertainment.

Hellfire is an add-on to the action RPG Diablo.

It adds two new dungeons to the game: the Demon Crypt and the Festering Nest, both crawling with all-new creatures. The Nest has the appearance of an insect hive and is populated with insectoid monsters and a boss creature called the Defiler. The Crypt is controlled by the demon Na-Krul, a former lieutenant of Diablo who turned on his master and now works on his own.

To master the challenges of the new dungeons, a new character class is available: the Monk can use staff weapons to attack several enemies at the same time and also is an expert at unarmed combat as well as an able spellcaster.

Also added are new spells, items and weapons. New magical items include oils (once applied, they add magical effects to weapons) and runes (they can be set on the ground as booby traps, unleashing magical effects on unsuspecting monsters).
