DIABLO II. ON OUR TERMS.

C9Realm vs LoD

Lord of Destruction is our foundation. We extend it with custom mechanics, selected D2R adaptations and community tools. See what actually changes in game, without mixing plans with live features.

Feature review: · 0.5.121Release history →

The baseline is unmodified LoD 1.13c/1.14d, mainly closed Battle.net play — not D2R. Beta means available but still in development.

Stash and items

Shared stash

Live

Standard SC/HC

Original LoD
A personal stash for each character.
C9Realm
Personal P, eight shared tabs I–VIII and a dedicated materials tab M.
Details and limits · Shared stash

Move items between characters through shared tabs. Materials have dedicated slots and counters. Socketed items, runewords and items taken off your character are supported. Use the stash while it is open, in a client started through the C9 launcher.

Stacks instead of a full backpack

Live

Standard SC/HC

Original LoD
Runes, gems and potions occupy separate slots.
C9Realm
Stacks of materials, rejuvenation potions, full rejuvenations and TP/ID scrolls.
Details and limits · Stacks instead of a full backpack

Refill your belt from a rejuvenation stack. Right-click TP to open a portal or ID to identify an item. Drag scroll stacks onto the matching tome; unused scrolls remain in the stack. See the FAQ for shortcuts and belt-refill rules.

Additional runewords

Live

Standard SC/HC

Original LoD
The original LoD runeword pool.
C9Realm
Additional D2R runewords, including Mosaic and Hustle.
Details and limits · Additional runewords

Mosaic includes its charge-retention mechanic. BH displays the added runeword names and runes. The guide lists rune order and eligible bases. These are selected adaptations, not a claim of full D2R balance parity.

Set upgrades in the Cube

Live

Standard SC/HC

Original LoD
Base-upgrade recipes do not cover set items.
C9Realm
Upgrade set-item bases to higher tiers.
Details and limits · Set upgrades in the Cube

Normal → Exceptional → Elite recipes keep your set item on an upgraded base. The new base changes its requirements. Check the recipe catalog for ingredients and restrictions.

Combat and on-screen feedback

Physical melee splash

Live

Standard SC/HC

Original LoD
No general melee-hit splash; AoE depends on the skill.
C9Realm
Part of the physical damage also hits nearby monsters.
Details and limits · Physical melee splash

The current version transfers 50% of the raw physical component to up to 6 neighbours, applying each target’s own resistance. Corrected combat-skill, kick and Blade Fury paths are included. Fire Claws fire damage and Maul stun do not currently spread; that extension is in development. Secondary targets do not add leech, Crushing Blow or item-proc rolls.

Read more →

Party Enchant

Live

Standard SC/HC

Original LoD
Cast Enchant on a selected target.
C9Realm
Enchant also covers nearby allies and their units.
Details and limits · Party Enchant

Party handling includes allied mercenaries and summons within range. Enchant strength and duration use native calculations. Target handling that could interrupt a game when casting outside town has been corrected.

Read more →

Party experience across the area

Live

Standard SC/HC

Original LoD
Experience sharing limited by distance from the kill.
C9Realm
Party experience is shared across the same area.
Details and limits · Party experience across the area

You need not stand next to the killer, but other experience eligibility rules still apply. This does not cover an entire act or all dungeon floors; party rules and level-based calculations remain.

Read more →

DPS meter

Live

Standard SC/HC

Original LoD
No table of damage dealt over time.
C9Realm
Physical, magic and elemental DPS for you or game participants.
Details and limits · DPS meter

The table covers the last 5 seconds. Drag it anywhere, switch Me / Players and hide it with the close button or .dps. It measures in-game combat, not a build’s theoretical potential.

Read more →

Buff timers

Live

Standard SC/HC

Original LoD
No combined panel counting down remaining buff seconds.
C9Realm
Active buff icons with a server-synchronised countdown.
Details and limits · Buff timers

The panel includes BO, BC, Shout, Enchant, Hurricane and druid transformations. Small icons near the bottom bar show time without opening another window. It covers supported buffs, not every state or effect in the game.

Your pace and endgame

.players on the realm

Live

Standard SC/HC

Original LoD
Player-count simulation outside closed Battle.net.
C9Realm
.players 1–8 online, without filling slots with extra accounts.
Details and limits · .players on the realm

The creator chooses difficulty, experience and NoDrop scaling. After the first kill, the manual value can only increase. Human presence is counted separately: its contribution may fall as people leave, but not below the requested setting. This does not instantly recalculate existing monsters’ HP.

Terror Zones

Live

Standard SC/HC

Original LoD
Fixed area levels, without an hourly TZ rotation.
C9Realm
15 area groups for XP, MF and runes, with an upcoming-rotation calendar.
Details and limits · Terror Zones

Zones apply on Nightmare and Hell and change on the full hour, in running games too. Monster-level scaling and +25% base experience diversify farming routes; access to a higher drop tier does not guarantee a valuable item.

Read more →

Personal Diablo Clone

Live

Standard SC/HC

Original LoD
A Battle.net event tied to server-wide SoJ sales.
C9Realm
Sell one SoJ on Hell to trigger the event in your game.
Details and limits · Personal Diablo Clone

No need to wait for collective ring sales. The trigger applies only to the seller’s game, at most once per game. It does not spawn Clone in everyone else’s games.

Choose your starting town

Live

Standard SC/HC

Original LoD
No command to save a preferred starting town.
C9Realm
.set home 1–5 saves a character’s preferred town.
Details and limits · Choose your starting town

On joining a new game, the character starts in the selected town if that act is accessible. The command does not unlock quests or acts.

Refresh gambling stock

Live

Standard SC/HC

Original LoD
Reopen the window for new stock.
C9Realm
An ODSWIEZ (Refresh) button without leaving the NPC window.
Details and limits · Refresh gambling stock

Only your gambling stock is refreshed. The button waits for a server response and has a short cooldown between uses.

Your character beyond the game

Build Lab

Live · beta

Website / community

Original LoD
Plan in game or with external tools.
C9Realm
Armory import, A/B comparison and 5 named loadouts.
Details and limits · Build Lab

Plan items, rolls and skills with Armory-style tooltips. Sign in to save a private plan and share a revocable link. Calculations are partial: this is not yet a complete DPS simulator. Loadouts exist on the website; they do not equip characters or move in-game items.

Holy Grail and achievements

Live

Website / community

Original LoD
Keep your own collection and challenge records.
C9Realm
Automatic find collection, achievements and rankings.
Details and limits · Holy Grail and achievements

Track Holy Grail, ethereal Hard Grail and achievement points. Finds are verified by the realm. When drop-source evidence is available, the monster and location are retained rather than guessed.

Read more →

Armory and statistics

Live

Website / community

Original LoD
Inspect your own equipment in the game client.
C9Realm
Equipment, sockets, weapon switch, mercenary and character history online.
Details and limits · Armory and statistics

Inspect item tooltips and character/session statistics. Move from the Armory into Build Lab planning without editing the character save.

Read more →

A community connected to the realm

Live

Website / community

Original LoD
Chat and ladder without Discord integration.
C9Realm
Linked accounts, leader roles, clans and a trade board.
Details and limits · A community connected to the realm

Discord carries realm events; the C9 Advisor answers questions and the Chronicle summarises the day. Ranking roles belong to the actual leader with a linked account, not the next person merely because the leader has not linked Discord.

A client you can customise

BH and optional helpers

Live

C9 client

Original LoD
Basic drop labels and the game’s map.
C9Realm
Richer drop labels and NUM1–6 toggles with saved preferences.
Details and limits · BH and optional helpers

BH 1.9.10-b3.1: NUM1 — lighting, NUM2 — weather, NUM3 — Infravision, NUM4 — reveal, NUM5 — navigation, NUM6 — monsters. All six start disabled in new profiles. Choices persist after restart and custom hotkeys are preserved. Disabling reveal cannot undo map discovery in the current game.

Automatic gold pickup

Live

C9 client

Original LoD
Click gold piles on the ground manually.
C9Realm
Pick up gold close to your character without an extra click.
Details and limits · Automatic gold pickup

The server still checks distance, ownership and carried-gold limits. This does not transfer excess gold into the stash or bypass your gold cap.

Read more →

Launcher, HD and multiple windows

Live

C9 client

Original LoD
The original client and its configuration.
C9Realm
An isolated C9 installation, D2GL HD, PL/EN and automatic updates.
Details and limits · Launcher, HD and multiple windows

The launcher prepares the client from your legal LoD copy without overwriting the source installation. Start each game window through the launcher and sign in to a different account. The stash helper runs independently of the visible launcher window.

Keep the rules at hand

DEVELOPMENT DIRECTION · NOT IN GAME YET

What’s next for C9Realm?

These are separate development stages, not features of the current client. Dates are not promised before testing is complete. The goal is more viable builds and better gameplay, not automatically easier gameplay.

  1. IN DEVELOPMENT

    Splash: elements and skill effects

    Extend splash to effects such as Fire Claws fire and Maul stun, and audit the Act V mercenary. Additional leech, Crushing Blow and random item effects are to remain limited to the primary target.

  2. DIRECTION · AUDIT

    Skills closer to D2R

    Compare changes to existing classes and mercenaries one mechanic at a time. Adapted runewords do not mean the full D2R balance has already been ported.

  3. PROTOTYPE · NOT LIVE

    In-game equipment loadouts

    Safe equipment swapping at the stash requires separate item and save tests. The 5 loadouts currently in Build Lab are website planning only.

  4. CONCEPT AND PROTOTYPES

    Circle of Nine

    New endgame after Hell Baal: extra bosses, unlockable portals and maps. Rules, rewards and balance remain under design; these portals are not live on the realm.
