The Hellfire dungeons are populated with new enemies that do not appear in the main Diablo quest, however. It should be noted, however, that there are almost no unique monsters found within Hellfire's exclusive dungeons. The new unique monsters, which appear as palette-swapped, but otherwise normal monsters with a unique name, also appear in the Diablo quest like any other. New shrines are found where shrines would normally be found.

Objects like oils, new weapons, rings and armor, and runes drop amid other more common kinds of items, and the new spellbooks, including books for two previously existing spells that did not have books, and scrolls are found in the same kinds of places.

The rest of the expansion integrates more fully into the main adventure. However, if the player speaks to Lester before reaching a certain point of the main Diablo quest, he will be hesitant to ask them to enter the new dungeons. In order to gain access to the dungeons, the player must speak with Lester, who is north of Tristram, near the herd of cows. Hellfire integrates into Diablo, and because of its design, its dungeons can be avoided entirely. The expansion pack adds several enhancements to Diablo, including an additional Monk class, two new dungeon settings, namely The Festering Nest and the Demon Crypts, additional quests to undertake, several extra game items, including oils which affect item statistics, runes that can be placed as traps, a new page of spells, new affixes for weapons and armor, new shrines, new miniboss enemy names, a noticeable boost to Diablo's strength and power, and a number of interface improvements.
