Diablo

A descent beneath Tristram

Diablo begins in the troubled town of Tristram and draws you into the cathedral above its underground labyrinth. The original game offers Warrior, Rogue and Sorcerer characters, with different abilities, equipment and approaches to combat. New gear and changing dungeon layouts make the next descent an opportunity to improve a character as well as uncover more of the story.

The setting gives the game a focused rhythm: a small town above, a dangerous labyrinth below, and an increasing sense of what lies at its bottom. This is the first Diablo, not Diablo II or the later games built around different classes and systems.

Try shareware, or use your own full game

d07RiV's DiabloWeb adapts the reconstructed Devilution engine to WebAssembly. Its included shareware lets you play the Warrior through the first two dungeon floors. It is an opening dungeon run, with Rogue and Sorcerer reserved for the retail game.

Supplying DIABDAT.MPQ from your own Diablo copy adds those two character choices and the rest of the base game's dungeon beyond the demo boundary. A store bundle containing Hellfire does not make that expansion part of this client's setup; the retail input here is Diablo's base-game archive.

The character belongs to this browser profile

The retail archive and your character are separate files. Importing DIABDAT.MPQ supplies game content; a save carries your progress. Moving only the archive to another browser will not bring the character with it.

Before switching devices, export the save and keep its original backup until the destination loads the expected character. The save controls below explain the .sv import and export steps for this client.

Which Diablo browser client is this?

This is the earlier DiabloWeb client. JohnImril's Diablo Web builds on that work with a newer browser interface and storage management, while DevilutionX is another project with its own feature set. Choose between their specific setup and save workflows rather than treating their shared Diablo ancestry as identical support.
