History of Diablo 2

The Making of Diablo 2

Diablo 2 was developed by Blizzard North (formerly Condor Games), led by David Brevik, Erich Schaefer, and Max Schaefer. Over 70 people worked on the game. It was announced in 1997 with a planned Q1 1998 launch, but development stretched past three years. The team entered a brutal crunch period in 1999 after missing key deadlines.

Famously, the game never had an official, complete design document. As Erich Schaefer put it: "Diablo II never had an official, complete design document... for the most part we just started making up new stuff." This creative freedom contributed to delays but also to the game's depth and replayability.

The iconic cover art by Gerald Brom originally featured a bullet hole in the Dark Wanderer's forehead, which was hidden following the Columbine High School massacre in 1999.

Launch Day

Diablo 2 launched on June 28, 2000 in North America (June 30 in Europe, July 26 on Mac). It was an instant phenomenon:

• 184,000 copies sold on day one
• 1 million copies sold globally within two weeks — earning it a Guinness World Record for fastest-selling PC game at the time
• 2 million copies within six weeks
• 2.75 million copies by end of 2000, with South Korea as the largest international market
• By 2001: 4 million copies worldwide

The game dominated awards season, winning PC Game of the Year, PC RPG of the Year, and Game of the Year at the 2001 Interactive Achievement Awards. It holds an 88 on Metacritic.

Lord of Destruction

The expansion Lord of Destruction launched on June 29, 2001 — exactly one year and one day after the base game. It added:

• Act V — set on Mount Arreat, culminating in the battle against Baal
• Two new classes — the Assassin and the Druid
• Runewords — 33 runes and the runeword system that would define endgame itemization for decades
• Ethereal items, jewels, charms, and hundreds of new Horadric Cube recipes
• 800x600 resolution — double the original 640x480
• Enhanced hirelings — mercenaries could now follow you through all acts and be equipped with gear
• Weapon swap — the W key to switch weapon sets became second nature

LoD sold over 1 million copies within a month, becoming the fastest-selling expansion pack ever at that time. It generated 9.2 million in US sales alone in 2001.

The expansion caused controversy when Blizzard simultaneously patched the base game to increase difficulty — many players felt this was forcing them to buy the expansion to access items and abilities needed to keep up.

Major Patches

Diablo 2's patch history is a story unto itself. Each major patch reshaped the entire game:

• 1.08-1.09 — the early era. Items from these patches became legacy collector's pieces when later patches changed their stats
• 1.10 (2003) — the biggest patch in D2 history. Added Uber Tristram, Pandemonium Event, ladder-only runewords, Annihilus and Hellfire Torch charms, synergies between skills, and completely rebalanced the game. This patch is what most veteran players think of as "the real Diablo 2"
• 1.11 (2005) — added Diablo Clone (Uber Diablo) spawning and Warden anti-cheat
• 1.13 (2010) — free respec via Akara (first quest reward per difficulty), and the ability to respec stats and skills completely changed how people played
• 1.14 (2016) — compatibility update for modern Windows and macOS, keeping the game alive on current hardware sixteen years after launch

Longevity & Records

Diablo 2's staying power was extraordinary. In 2010 — a full decade after release — 11 million users were still playing Diablo 2 and StarCraft on Battle.net. The Diablo Battle Chest was still charting in the top 10 PC games as late as 2010, and ranked as the 19th best-selling PC game of 2008 — eight years post-release.

The game has appeared on virtually every "best of" list in gaming: #21 on Time Magazine's "50 Best Video Games of All Time" (2016), #8 on Game Informer's "Top 100 RPGs", and #6 on IGN's "Top 10 RPGs of All Time."

Diablo 2: Resurrected

Diablo 2: Resurrected launched on September 23, 2021 on PC, PlayStation 4/5, Xbox One/Series X|S, and Nintendo Switch. It featured remastered graphics, re-rendered cutscenes, cross-progression between platforms, controller support, shared stashes, and countless quality-of-life improvements — while preserving the original gameplay underneath.

In 2026, the expansion Reign of the Warlock added the Warlock class (voiced by Rahul Kohli), bringing D2R's roster to eight classes and proving the game still had new chapters to write over two decades after its original release.

Ith Items

"Ith" became the universal shorthand for hacked items in Diablo 2 — even items that had nothing to do with the Ith rune. The name originated from a specific exploit: the Ith rune (#6) was used in crafted runeword formulas that, when manipulated through memory-editing tools, could produce weapons with damage values in the tens of thousands.

The most common Ith items included:

• Ith Bows — the most iconic variant. A bow (often a Stag Bow or Short Bow for speed) with manipulated rune values that dealt 30,000+ damage per shot, one-shotting any monster or player in the game. In PvP, a single Guided Arrow from an Ith bow meant instant death.
• Ith Swords & Axes — melee versions with equally absurd damage, often combined with impossible attack speed modifiers
• Ith Armor — defensive gear with impossibly high defense values, massive life bonuses, or stacked resistances beyond the normal cap
• "White" Ith items — items that appeared as plain white (non-magical) but carried hidden modifiers far beyond what the game normally allowed

These items were created through packet manipulation and memory editing — tools like Hero Editor and various hex editors could modify item data before it was sent to the server. On open Battle.net, where characters were stored locally, Ith items were everywhere. On closed Battle.net, they were rarer but still appeared through duping exploits and server-side vulnerabilities, especially in earlier patches before Blizzard tightened validation.

The term "Ith" eventually became generic slang for any obviously hacked item, regardless of whether it actually contained Ith runes. Seeing someone in a public game wielding an Ith bow was an immediate signal to either leave or accept that you were about to die repeatedly. For many players, Ith items were their first encounter with online cheating.

Occy Ring

One of the most iconic bugged items in Diablo 2 history. The Occy Ring was a ring that had the stats of The Oculus (Swirling Crystal unique) — a powerful sorceress weapon — crammed into a ring slot. It offered +3 to all skills, +20% faster cast rate, resistances, and magic find, all in a ring.

These existed due to item generation bugs and were primarily found on closed Battle.net through duping or trade. Blizzard eventually patched the bug that allowed their creation, but existing copies circulated for years, becoming status symbols and high-value trade items.

Bugged Tal Rasha's

Tal Rasha's Guardianship (the armor piece of the Tal Rasha's Wrappings set) had versions that were "bugged" with abnormally high defense values. The bugged version could roll significantly higher defense than intended due to an interaction with the ethereal bug and superior/socketing mechanics.

Players who had the bugged version guarded them fiercely, as Blizzard patches eventually fixed the creation method but didn't remove existing copies from the economy.

Sigard's Stealth (Sigon's + Stealth Bug)

This was a classic early-game exploit. By equipping pieces of Sigon's Complete Steel set and combining them with certain other items, players could achieve absurdly high stats at low levels. The name "Sigard's Stealth" became shorthand for various low-level dueling setups that exploited set bonus stacking bugs.

Low-level dueling (LLD) had its own entire meta built around these kinds of interactions, and dedicated LLD players spent countless hours perfecting their level 9 or level 18 characters.

Bugged Manas (BManas)

"BManas" or "Bugged Manas" were rings and amulets with impossibly high mana rolls that shouldn't have been possible within the game's normal affix tables. These items were created through various crafting and gambling exploits in early patches where the affix pool wasn't properly validated. A bugged mana ring could roll hundreds of extra mana — far exceeding what any legitimate combination of affixes could produce.

BManas became prized possessions for casters and energy shield sorceresses, where the massive mana pool translated directly into survivability. They were especially valued in PvP where every stat point mattered.

Snatchii's Gloves & Famous Rares

Snatchii's gloves were among the most famous rare items in Diablo 2 history — a pair of rare gloves with a near-perfect combination of affixes that became legendary in the trading community. In an era before crafted gloves dominated the meta, finding rare gloves with +2 to a skill tab, 20% increased attack speed, life leech, and resistances was like winning the lottery.

The D2 community had a tradition of naming godly rare items after their owners or finders. These items became celebrities in their own right, with their own trade histories and reputations. Entire forum threads would be dedicated to showcasing and debating whether a particular rare was "GG" (good game — meaning perfect) or not.

The Ethereal Bug

One of the most well-known and long-lasting bugs in D2. Ethereal items had 50% bonus defense (armor) or damage (weapons) but couldn't be repaired and would eventually break. The bug: if you socketed an ethereal item using the Larzuk quest reward or the Horadric Cube, the ethereal bonus would be applied again during the socketing process, stacking the bonus. This meant bugged ethereal items had significantly higher stats than intended.

This was especially impactful for mercenary items, since mercenary equipment doesn't lose durability. A bugged ethereal Gladiator's Bane or Shaft Stop could hit defense values that looked fake to anyone who didn't know about the bug.

Constricting Ring & Other Unobtainables

Items like the Constricting Ring existed in the game's data files but were never intended to drop. They had extreme stats (Constricting Ring drained life) and could only appear through hacks or bugs. Other examples include the Amulet of the Viper and various "white" unique items that existed in code but had no legitimate drop path.

Godly Rares & Crafts

Before runewords dominated the meta (especially after 1.10), rare and crafted items were king. Cruel prefix weapons (massive enhanced damage), Jeweler's prefix armor (4 sockets on magic items), and crafted blood gloves with crushing blow + life leech + attack speed were the most sought-after items in the game.

Some of these items were so rare that finding one was a once-in-a-lifetime event. Players would run the Hellforge quest, gamble millions of gold, and craft thousands of items chasing the perfect roll. The 1.10 patch shifted the meta toward runewords, but pre-1.10 rares remained valuable collector's items for years.

The 08 Valkyrie Wing & Legacy Items

"08" items (from patch 1.08) were another category of coveted gear. Certain unique items from earlier patches had different — often superior — stats compared to their later versions. The 1.08 Valkyrie Wing had higher stats than post-patch versions, and 1.08 Arkaine's Valor could roll with 2 sockets. These legacy items couldn't be found anymore after the patch, making surviving copies extremely valuable.

Similarly, 1.09 items sometimes had properties that were nerfed in 1.10. Players who held onto their pre-patch gear found themselves sitting on gold mines.

What Were Hybrid Runewords?

Hybrid runewords were one of the most fascinating exploits in Diablo 2 history. Players discovered that by using specific timing exploits during the runeword creation process, they could create items that combined properties of multiple runewords into a single item.

How They Worked

The most common method involved manipulating the game's socket-filling process. By using packet-editing tools or precise timing with town portal scrolls, players could interrupt the runeword creation mid-process. This could result in:

• Stacked runeword properties — where bonuses from two different runewords appeared on one item, such as Enigma's teleport combined with Fortitude's damage
• Runewords with wrong rune combinations — the visual runes in the sockets didn't match the runeword name or properties that appeared
• Partial runewords — items that triggered a runeword bonus but still had empty sockets remaining, allowing further customization

Impact on the Economy

Hybrid runewords were highly sought after on certain realms. An armor combining Enigma's teleport with Fortitude's enhanced damage, or a weapon stacking Grief and Last Wish properties, could trade for astronomical amounts. However, they were always considered illegitimate by most of the community and were a bannable offense on closed Battle.net.

Some players specialized in creating and trading hybrid runewords, building entire reputations (and fortunes in forum gold) around the craft. The debate over whether owning a hybrid made you a cheater or just a savvy trader was a perennial forum argument.

Patch History

Blizzard addressed hybrid runewords in several patches, tightening the runeword creation validation and adding server-side checks. By the later patches of Lord of Destruction (1.13+), most methods of creating hybrid runewords had been eliminated. In Diablo 2: Resurrected, these exploits are effectively impossible due to modern server-side validation.

Maphack

MousePad's Maphack (later BH Maphack) was arguably the most-used third-party tool in D2 history. It revealed the full map, showed item levels, monster immunities, and had dozens of quality-of-life features that Blizzard wouldn't officially add for over a decade. Many features from popular maphacks were eventually incorporated into Diablo 2: Resurrected — item level display, monster immunity indicators, and enhanced map overlays all trace their origins to the maphack scene.

TMC Hack

The TMC Hack (The Mousepad Collection, named after community member MousePad) was one of the most notorious multipurpose hack packages for Diablo 2. It bundled together a collection of exploits, hacks, and tools into a single downloadable package:

• Maphack — full map reveal and item/monster info overlays
• Chicken — auto-exit the game when health dropped below a threshold, saving hardcore characters from death
• Pickit — auto-loot specific items the moment they dropped, faster than any human could click
• Far Cast — cast spells from outside normal range
• Various PvP hacks — teleport hacks, desync exploits, and hostile automation

TMC became so widely distributed that it practically defined the hacking scene on closed Battle.net. New versions would release after each Blizzard patch, and the cat-and-mouse game between TMC developers and Blizzard's Warden anti-cheat system became a saga unto itself. Getting "Warden banned" after a TMC update was a rite of passage for many players who dabbled in the dark side.

D2BS & Kolbot

D2BS (Diablo 2 Botting System) was the definitive botting framework for Diablo 2, emerging from the BlizzHackers community. Unlike simple auto-clickers, D2BS was a full JavaScript scripting engine injected into the game client, allowing users to write complex automation scripts.

Kolbot was the most popular script collection for D2BS. It could run entire characters autonomously — leveling from 1 to 80+, farming specific bosses (Mephisto, Pindleskin, Baal), managing inventory, muling items to storage accounts, and even handling game creation cooldowns. A single player could run 4-8 bot instances simultaneously across multiple game windows.

The botting economy was enormous. Entire ladder seasons were shaped by bot farms flooding the market with items and runes. Some players ran bot operations as a side business, selling items and high runes for real money or forum gold.

Other Notable Bots & Tools

• D2Loader — allowed running multiple Diablo 2 instances simultaneously, essential for multi-boxing and bot farms
• AutoIt scripts — simpler bots built with the AutoIt scripting language, popular for basic farming loops
• Mousepad's D2 Maphack — the original standalone maphack before it was absorbed into TMC
• D2Hackit — an older modular hack platform that predated TMC, with a plugin system for loading different hack modules
• Etal — another popular botting script that competed with Kolbot, known for its Baal run automation

Hero Editors

Programs like Hero Editor, Jamella's D2 Editor, and Shadowmaster became household names in the D2 community. These tools let you edit every aspect of a locally-saved character — stats, skills, items, waypoints, quests. While primarily used on open Battle.net (where characters were stored locally), they also served as item databases and theorycrafting tools.

For many players, hero editors were their first introduction to the concept of modding a game. The simple act of giving yourself a Windforce or a pair of Stone of Jordans in single-player scratched an itch that kept people engaged with the game even when they weren't playing on Battle.net.

Warden & The Anti-Cheat War

Blizzard's Warden anti-cheat system was introduced to combat the rampant hacking. It ran as a background process that scanned for known hack signatures in memory. The back-and-forth between hack developers and Warden was relentless:

• Blizzard would update Warden to detect a new hack → mass ban wave
• Hack developers would reverse-engineer the new Warden signatures → release an updated version
• Players would wait nervously after each update to see if it was "Warden safe"
• Some ban waves caught tens of thousands of accounts simultaneously

The Warden system was controversial — privacy advocates argued it was essentially spyware scanning your computer's memory. Blizzard maintained it only looked for known cheat signatures. The debate presaged modern anti-cheat controversies by over a decade.

The Wild West

Open Battle.net was where chaos reigned. Unlike closed Battle.net (where characters were stored server-side), open B.net used locally-saved characters. This meant anyone with a hex editor could modify their character files to have any items, stats, or skills they wanted.

The Culture

Open B.net developed its own unique culture:

• "Legit" communities — groups of players who chose to play without hacks and policed their own games, often using honor systems and community vouching
• Hack vs. Hack PvP — where the goal was to out-hack your opponent with the most absurd character builds imaginable. Characters with 32,000 strength, instant-kill spells, and items with every mod in the game were common
• Town kill hacks — some players figured out how to kill other players in town, a supposedly safe zone, causing rage and ragequits across the realm
• Crash hacks — programs that could crash other players' games or even the entire game server, used for griefing or to disrupt duels

The Dupe Methods

Duplication exploits shaped Diablo 2's economy more than any other factor. Major dupe methods included:

• Town Portal dupe — one of the earliest methods, involving precise timing with town portals to duplicate items on the ground
• Trade window dupe — exploiting the trade window to duplicate items during the trade process
• Crash dupes — intentionally crashing the game server at specific moments to roll back item transactions while keeping copies
• Perm methods — duped items initially weren't "permanent" and would disappear ("poof") when the game closed. Players developed elaborate methods to make duped items permanent.

Stone of Jordan as Currency

The Stone of Jordan (SoJ) became the de facto currency of Diablo 2. Its relatively consistent stats and universal usefulness made it the gold standard for trades. "40 SoJs" or "2 SoJs" became price tags everyone understood.

This was also tied to the Uber Diablo mechanic — when enough SoJs were sold to vendors on a server, Uber Diablo (Diablo Clone) would spawn. This created an entire meta around SoJ selling and tracking.

Forum Gold (FG)

Eventually, the community created its own cross-server, cross-season currency through sites like d2jsp. "Forum Gold" (FG) became a controversial but widely-used currency that persisted across ladder resets, fundamentally changing how the economy worked. Debates about whether FG was good or bad for the game continue to this day.

BlizzHackers

BlizzHackers was one of the most influential underground communities in Diablo 2 history. Originally a forum dedicated to reverse-engineering Blizzard's games, it became the birthplace of many of the hacks, bots, and exploits that defined the D2 experience. Members dissected the game's code, documented the packet protocol, and published findings that powered nearly every major hack and bot in the game's history.

The community had a complicated reputation — many of its members were genuinely talented programmers who contributed to the deep technical understanding of how Diablo 2 worked. Research from BlizzHackers led to the creation of private servers, custom mods, and tools that the broader community eventually embraced. At the same time, it was also the source of the most destructive exploits and dupe methods that plagued Battle.net for years.

d2jsp & Forum Gold Controversy

d2jsp (Diablo 2 Java Script Pages, founded by Paul "njaguar" Shortino) became the largest Diablo 2 trading community and one of the most controversial sites in the game's history. Its introduction of Forum Gold (FG) — a virtual currency that persisted across ladder resets and even across games — fundamentally changed how D2's economy functioned.

The drama around d2jsp was endless:

• Pay-to-win accusations — players could buy FG with real money, then use it to buy items on a fresh ladder. Veterans with massive FG reserves could gear up within hours of a reset while newcomers had nothing.
• Scamming — despite a mediator system, scams were rampant. Forum drama over failed trades, chargebacks, and mediator corruption filled thousands of threads.
• "FG ruins the economy" — a perennial debate. Critics argued FG removed the thrill of self-found play and made item prices meaningless since everything had a FG value. Defenders countered that FG provided stability and cross-ladder liquidity.
• njaguar's profits — the site generated significant revenue from FG sales and premium memberships, leading to accusations that the entire system was designed to enrich its founder at the community's expense.
• RMT gateway — d2jsp was widely seen as a "legitimate" gateway to real-money trading (RMT), blurring the line between in-game trading and commercial transactions.

Love it or hate it, d2jsp shaped Diablo 2 culture for over a decade and remains active to this day, having expanded to cover other games while maintaining its D2 roots.

USEast vs. USWest vs. Europe

Each Battle.net realm had its own distinct community and culture. USEast was the largest and most active, home to the biggest trading communities and the most competitive PvP scenes. USWest had a smaller but tight-knit community that often looked down on East's chaos. Europe had its own trading language and customs, and Asia was known for extremely efficient botting operations and different meta preferences.

Cross-realm drama was common — realm-specific duping methods, different economies, and regional rivalries all contributed to a fractured but passionate global community. When a major dupe hit one realm, refugees would flood to another, bringing their drama with them.

Ladder Resets

Every ladder reset was an event. The entire community would prepare, plan their rush strategies, and race to be the first to reach level 99 or find specific items. The first few hours of a new ladder were some of the most exciting moments in gaming — everyone starting fresh, rushing through acts, and the first high runes dropping felt electric.

Realm Down

"Realm Down" was the bane of every serious player's existence. Blizzard's anti-spam measures would temporarily ban your IP from creating or joining games if you did so too quickly. For Baal runners, chaos runners, or MF runners who were cycling games rapidly, getting "realm downed" was an infuriating but regular occurrence.

Rust Storm

Blizzard's periodic anti-dupe sweeps were called Rust Storms. During these events, the servers would scan for duplicated items and delete them. The aftermath was dramatic — players would log in to find their inventories gutted, and the economy would temporarily collapse before rebuilding. Some players lost legitimate items that were falsely flagged, adding to the controversy.

The Pindle Run Era

Pindleskin became the most-killed monster in gaming history. His proximity to a waypoint, combined with his ability to drop almost every item in the game, made "Pindle runs" the go-to farming method for years. Players would kill Pindleskin thousands of times in a single day, perfecting their routes to sub-30-second runs.

Baal Runs & Chaos Sanctuary

Public Baal runs were the backbone of the D2 leveling experience. Channels like "Baal-1" through "Baal-99" on USEast were always full. The etiquette was established — don't take the last portal, don't go AFK, and always say "TP up" when the throne room was clear. Chaos Sanctuary runs served a similar purpose, and debates about which was more efficient raged for years.

Blood Moor Dueling

The Blood Moor outside the Rogue Encampment became the unofficial PvP arena. "Duel games" were a staple of Battle.net, with names like "PvP LLD 09" or "NH GM Duels" (no hostility, guided missile — a set of community rules). The PvP community developed its own terminology, tier lists, and honor codes.

BM vs. GM

"Bad Mannered" (BM) vs. "Good Mannered" (GM) was a constant debate. GM dueling had rules — no potions in some formats, no chicken (leaving game when about to die), no use of certain overpowered skills or items. BM was anything goes. Both had their devoted communities.

Classic PvP Builds

Some PvP builds became legendary:

• Bone Necromancer — the ultimate GM dueler, bone spear could pierce through everything
• Hammerdin — controversial in PvP due to the invisible hammers
• Ghost (Assassin) — Weapon Block + Mind Blast + traps made them nearly unkillable
• V/T (Vengeance/Templar) Paladin — the rare hybrid that could compete against everything
• Wind Druid — Tornado's random pathing made it incredibly hard to dodge
• WWS Zon (Widowmaker Guided Arrow) — before the nerf, Guided Arrow could pierce and re-hit the same target

Major Mods

The modding community kept Diablo 2 alive long after official support waned:

• MedianXL — a total conversion that's practically its own game, still actively updated
• Path of Diablo — added quality-of-life features and balance changes while keeping the core game intact
• Project Diablo 2 — similar philosophy to PoD with seasonal ladders and community events
• Eastern Sun — one of the earliest major mods, expanded endgame significantly
• Plugy — single-player mod that added infinite stash, ladder-only runewords, and Uber events to offline play. For many solo players, Plugy WAS Diablo 2.

The Legacy

Diablo 2's impact on gaming cannot be overstated. It defined the ARPG genre, created the template for loot-driven games, and built a community that persisted for over two decades. When Diablo 2: Resurrected launched in 2021, many of the players who logged in were returning veterans who still remembered their first Shako drop, their first Jah rune, or the heartbreak of losing a hardcore character to a lag spike.

The bugs and exploits weren't just problems to be fixed — they were part of the shared experience that made Diablo 2 unforgettable.
