Diablo is basically Blizzard's second most famous action role-playing series, next to Warcraft, where instead of fighting orcs, you're on a mythical quest to murder everyone's friendly neighborhood dark-lord.

Diablo was originally developed as a turn-based game by Condor Inc. Condor was later bought by Blizzard Entertainment and transformed into Blizzard North. As part of the arrangement, Diablo would have to include real-time combat instead of turn-based combat, and feature multiplayer. Blizzard was convinced that these two features were key after the success of Warcraft. It turns out that they were correct. David Brevik experimented with real-time combat by simply reducing the turn length to 0 seconds, and the rest is history.

NPCs

Tremain

Originally, the town of Tristram was going to feature a priest, Tremain, who would've guided you in the last few missions, only to have been killed by a cursed sword. It's clear that this character was cut fairly early on - he has a very incomplete set of dialogue that doesn't even include gossip about the other townsfolk. Graphics for this character exist in /towners/priest/priest8.cel, implying that he was either the eighth character developed or that there were eight different iterations of his graphics. His dialogue is in /sfx/towners, along with all the other townsfolk.

Graphics

File Name	Audio	Transcription	Notes
priest00.wav		All I can do now is pray for us all.	Most likely his greeting when you interact with him, just like with other characters.
priest01.wav		I seek a champion to undertake a serious duty and the people of this town speak well of your courage and skill. The Archbishop Lazarus, once King Leoric's most trusted advisor and a member of our order, has taken the path of evil. Not long ago, Lazarus lead a party of simple townsfolk into the labyrinth to find the king's missing son, Albrecht. Only a few of them escaped with their lives. Curse me for a fool! I should have suspected his veiled treachery then, for I have learned that it was Lazarus himself who kidnapped Leoric's son and has since hidden him within the labyrinth. I still don't understand why the Archbishop has turned to the darkness, or what his interest is in Albrecht. Unless...he means to sacrifice him at the full moon! That must be what he has planned! The survivors of his rescue party say that Lazarus was last seen in the deepest bowels of the labyrinth, some sixteen levels beneath the cathedral. You must hurry, and save the prince from the sacrificial blade of this demented fiend!	Lazarus is on the fifteenth level in the final game instead of the sixteenth (which has Diablo). Sacrificing the prince on the full moon could possibly be related to the Strange Map quest, which also involves a time limit based on celestial bodies. The existence of this line creates a paradox; if Tremain has been killed by Shadowfang, he shouldn't be able to give this quest. This could mean that either the story was slightly different before, or that Lazarus quest could either appear or not, instead of being mandatory. This is also could be simply an oversight that they fixed by giving this quest to Deckard Cain.
priest02.wav		Why do you delay? Time is of the essence! The prince and the people of this kingdom are counting on you!
priest03.wav		So, Lazarus has paid the price for his betrayal, and justice is served. For your services this day, I bestow this mace unto you. Its name is Lightforge, and it is the holiest of our order's artifacts. As I am the last of this order, I entrust it to you. May the light guide you.	Lightforge exists and can be found in the final game as a random unique item. Deckard Cain is also revealed to be the last member of an ancient order; perhaps this plot point was reused.
priest04.wav		This is terrible! Lazarus will surely burn in hell for his horrific deed. Although the boy you describe may not be our prince, I believe that Albrecht may yet be in danger. Whatever vile power lies beneath the ground has assuredly secured its foothold in our world. All I can do now is pray for us all.	This is possibly the "bad ending" if "Albrecht" is not saved in time.
priest05.wav		I have had a most disturbing experience that I must share with you, my friend. Earlier today, I was called upon to help one of the men that escaped from the labyrinth. He was deranged, violent, and kept lashing out at all of those who tried to calm him. I suspected that he was possessed by some sort of demonic entity, and so, began to drive the evil from within him. After many hours, I was able to exorcise a demon who called himself Fleshdoom, but the hellion fled into the labyrinth. You may think that I am mad, but after speaking with the man and battling with Fleshdoom, I believe that the labyrinth has somehow become a gateway to the underworld. As you descend deeper, you may find yourself upon the doorstep of hell itself. Finally, the man who was possessed retained memories of an ancient demon blade named Shadowfang. If you find the demon Fleshdoom, beware this foul sword. While I fear the dangers below grow even greater, you must find Fleshdoom and slay him. Bring the sword to me and I can destroy it. But do not wield it; for its power can corrupt absolutely.	This begins the Shadowfang/Fleshdoom quest.
priest06.wav		Fleshdoom's demise is a great good to the world, yet Shadowfang remains. It must be found and destroyed. Do not attempt to use the demon blade, champion. It will corrupt and madden any mortal who wields it. I alone can end its dark evil.	Presumably this would be used when talking to Tremain after killing Fleshdoom but while not possessing Shadowfang.
priest07.wav		Light be praised! You found the cursed demon blade. Only its destruction can ensure the safety of us all. Wait. What treachery is this? Ow! It burns! Hellfire, consuming me! You must take this to the Hellforge, and cast it in before...no!	Tremain dies after saying this line.

The other townsfolk have unused, voiced gossip lines about Tremain:

Speaker	Audio	Transcription	Notes
Adria		Faith is absolute belief in the unseen. The priest Tremain is from a holy order long asleep in this land. He keeps a promise and a charge issued ages ago and sustains a union with realms that even my vision cannot reach. He knows much, but not as much as he believes.
Deckard Cain		Tremain is an occasional visitor to our town, and seems to have little problem coming and going. It is strange how at times anyone that tries to leave Tristram is hunted down and slain by the cloaked rides, and at other times it is a simple matter to leave. I think that it is that uncertain fear that keeps some of us here. But we are glad for Tremain's bravery and luck in keeping some contact with the rest of the kingdom.
Farnham		I haven't ever see a priest around here. If I did I'd kick him right in the *BBBBUUURRRPPP* Can't even keep a church free of those Hell spawn - bastards. What good are they, those holy men? Liars! Liars!
Gillian		I really don't know much about the priest Tremain. He never visits the tavern, preferring to keep to the company of Pepin and Cain. Perhaps it is because they, too, have more scholarly pursuits.
Griswold		The priest Tremain. *Griswold Noise* He's a solitary fellow who has no time for most of us. He seems to prefer the company of Pepin or Cain. Ah, that's fine by me. I respect his passion and his commitment to his order, but I've no time for his prattling.
Ogden		The priest Tremain is a bit of a mystery. He certainly never stays here, and he often comes and goes to many of the nearby towns.
Pepin		His Holiness is a wondrous man of great knowledge and understanding. He has shown me many cures for rare and deadly diseases. He brings me books and reagents for my work whenever he can. But I fear that he may some day take on a task that is too great even for him.	This is foreshadowing a later event.
Wirt		Yeah, Tremain. He gets around, doesn't he? Or haven't you heard? My friends in some of the other towns say that he passes through. Picking up some books here, a pinch of bat claw there. Never seems to have the kind of problems most do getting in and out of Tristram, that's for sure.

Unused Walk Sequences

Walk sequences exist for Griswold, Gillian and Ogden in eight directions. All town NPCs are stationary in the final game, and these sequences go unused.

Cut Spells

In many prerelease screenshots, the spellbook can be seen with 6 tabs instead of the 4 that are present at release. If the player clicks at a very specific spot on the spellbook page, they can access the fifth page, which doesn't show any spells on it.

Sentinel/Sentinal

Sentinel (misspelled as "Sentinal" in the code) unleashes a floating eyeball that shoots fireballs at enemies. Given that this is very similar to Guardian, it was probably cut for this reason. Spell icons, graphics and code all exist for this spell, but it is unable to appear as a book or charges on a staff and the code for it is incomplete. The spell would've used a red book, similar to Fire Bolt and other fire spells.

	The fireball sent by the Sentinel?
	The sentinel in its idle state.
	The sentinel spawning.

The Town Portal spell uses a sound effect called sentinel.wav instead of portal.wav (which goes unused), indicating that this sound effect was probably used for the Sentinel spell at one point.

sentinal.wav (used for Town Portal)	portal.wav (unused)

Blood Boil

Blood Boil would've slowly killed a target in melee range, while also dealing damage to yourself. A spell icon and sound effects exist for this spell, both of which were re-used (except bldboil.wav, which is listed here) in Hellfire for the Rage skill. Unfortunately the code for it in the retail game is incomplete and does not work correctly.

File	Description
	The spell icon for Blood Boil.
	This would've played if a character died, similar to the Stone Curse shattering effect (also cut).

Blood Ritual

Blood Ritual exchanges health for mana in various prototypes, but does not function in the retail game. A spell icon exists for this spell. Notable is that the spell icon design was later reused for the Slow Missiles skill in Diablo II.

Doom Serpents

Doom Serpents appears to be a missile skill that shoots serpents at your foes. A spell icon exists for this spell, but it is a duplicate of the Guardian spell icon. Additionally, there are sound effects, graphics and an entry in the spell table within the code.

File	Description
	The spell icon for Doom Serpents.
	The missile.
	The "explosion" effect when it hits something.

Invisibility

This spell would've most likely made you invisible for a period of time, but the code does not function. A spell icon and a sound effect exist for this spell. The design of the spell icon was later reused for the Teleport skill in Diablo II.

File	Description
	The spell icon for Invisibility.

Etherealize

This spell would make you stop taking damage for a certain period of time.

File	Description
	The spell icon for Etherealize.
	This icon would appear above your head, similar to Mana Shield.

Mind Mace

All that exists of this spell in the retail game is a single graphic, mindmace.cel, which looks like a spinning mace.

• 

Unused Misc Spell Icons

There are five additional unused spell icons that are not attached to any particular spell. Given that they have a red tint to the icon, they would've costed Life to cast instead of Mana.

Unused Areas

To do: Get screenshots of these. According to the Diablo Evolution, one unused Catacombs pattern, with a circle in the middle of the room (screenshot with it can be seen on Alpha 3 page) is still in game files. Check it out.

The Hall of Heroes

levels/l1data/hero1.dun and levels/l1data/hero2.dun are unused sections of the Cathedral map. Originally, they were related to the Catacombs sections; in the pre-alpha versions of the game, the Catacombs were accessible throught a special room called "The Hall of Heroes", where you needed to read a book to open the door, but later the entrance to the Catacombs was changed to just a stairwell. The text was later re-used for the Chamber of Bone quest, and the mention of "The Hall of Heroes" was left as an oversight.

• 
• 

Old Butcher's Chamber

levels\l1data\rnd5.dun is an old variant of the Butcher's Chamber. Still can be seen on old screenshots.

• 

The Maze

levels/l1data/Lv1MazeA.DUN and levels/l1data/Lv1MazeB.DUN are unused - they are part of an unused Maze level. They were used for an old variant of the Ogden's Sign quest, that originally used the same name—"The Maze". In the final game, it uses a little sub-area instead of separate level.

The Lair?

levels/l3data/lair.dun is not used. It was likely intended for the cut quest involving worms beneath the town.

Hidden Developer Messages

Installer

Hidden between Diablo's horns in the setup and boot executables for the first Windows release:

Original	Edited

The text on the left reads "BUY WAR II", while the other set reads "NATALIE PORTMAN ROCKS". While it's not 100% certain what the former refers to, it's most likely Warcraft II, another Blizzard game.

Diablo's Lair

Entering Diablo's lair plays an ominous-sounding demonic chant. Reversing the audio, however, reveals the decidedly non-demonic message of "Eat your vegetables and brush after every meal." This is satirizing the Satanic Panic, in particular the idea that certain songs could be played backwards to reveal demonic messages.

Original	Reversed

Mac OS Dialogs

Some development remnants survive in the resource fork:

(Diablo never would support 680x0 processors.)

To do: There are two "Click here to use this monitor" dialogs: a plain black-on-white design and one matching the game's aesthetic. The former is likely unused.
