Travel

Cartel Travel Pace

After 5 seconds out of combat you move 30% faster, on foot and mounted. A buff with the Goblin Rocket Boots icon shows while it's on. It switches off the moment you enter combat and comes back 5 seconds after.

Speed, yards a secondVanillaWith the pace
On foot7.09.1
Cartel Pack Mule9.111.83
Level 40 mount (60%)11.214.56
Level 60 mount (100%)14.018.2
  • It's a flat 30% on top of whatever speed you have. Sprint, Aspect of the Cheetah, Travel Form and Ghost Wolf get the 30% and nothing more; Mithril Spurs, Carrot on a Stick and mount-speed enchants still add.
  • Never in dungeons, raids or battlegrounds, while dead, on a flight path, or in combat. Walking, swimming and ghost speeds are vanilla.
  • The anticheat knows about it: long runs at full pace are never flagged.

Hearthstone

The Hearthstone's cooldown is 30 minutes instead of an hour.

The Cartel Pack Mule

Your first mount, from level 20, with no riding skill needed. It's a riding horse in a golden-dun pack-mule coat, leased from the Mithril Cartel: "It hauls, it doesn't fight."

  • Speed: 30% (11.83 yards a second with the travel pace).
  • How to get it: Trade Prince Mithrix's quest A Mule for the Road, from level 20: bring 10 [Wool Cloth] and pay 250,000 MITH at the turn-in. One mule per character.
  • The item: uncommon, unique, bind on pickup, 3-second cast.
  • Level 40 and 60 mounts, riding skill and their prices are vanilla's.

Controls

The defaults are 1.12's, with one change: A and D strafe and the arrow keys turn. Q and E are left free.

Everything can be rebound in Game Menu, Key Bindings, and Defaults brings back this layout. Your bindings are saved in your browser, per account and character.

In the browser, the game keeps Tab, F1 to F12, Alt, Space and the arrows for itself, so the page doesn't scroll or switch focus while you play. Copy and paste stay with the browser. Ctrl+W can't be stopped by a web page, so the page asks before closing while you're in the world.

Interface and addons

The interface is the stock 1.12 one. The server installs five addons for everyone; they're on by default, and you can switch any of them off with the AddOns button at character select. Only addons with a free licence are shipped.

AddOnWhat it doesLicence

Instant Quest Textonoff
Mithril moneyon (/console mithrilMoney 0 and /reload bring gold, silver and copper back on your screen)

Also new: the login screen has one Sign in with Phantom button instead of an account name and password, the loading screens are repainted, and friendly nameplates stay on between zones.

Mithril in game

Gold, silver and copper are replaced by one number and a Mithril coin everywhere money appears: bags, merchants, repairs, the auction house, mail, trade, quest rewards and the loot window. 1 Mithril is 1 vanilla copper, so prices are vanilla's: a [Linen Cloth] still sells for 13 MITH.

  • Chat reads "You loot 1,500 Mithril" and "Not enough Mithril".
  • Money boxes take one number: type 15000, or 25k.
  • Long numbers shorten only where a row is too narrow (12.5K, 1.2M), and hovering shows the exact amount.
  • Fresh loot shows as still settling for about two seconds while it's recorded on chain; until then it can't be traded, mailed or withdrawn.

The Mithril Cartel

Mithril Exchange goblins

Goblins that send the Mithril in your bags to your wallet, and bring it back. They stand beside the bankers in Stormwind, Ironforge, Darnassus, Orgrimmar, Thunder Bluff, Undercity, Booty Bay and Gadgetzan, in the inns of Everlook, Goldshire, Razor Hill, Kharanos, Dolanaar, Bloodhoof Village and Brill, and right in front of you in every starting area.

  • Withdraw: the page shows your purse and offers 1%, 10%, 25%, 50% or all of what can go now, or any amount you type. One free withdrawal every 15 minutes; any amount from 1 Mithril. A window shows your wallet's balance and when the Mithril has arrived.
  • Deposit: opens a window where Phantom signs. No SOL needed.
  • Chat commands: .withdraw 25000 or .withdraw max from anywhere; .deposit, .deposit 25k or .deposit max.

The details: Withdraw and deposit.

Trade Prince Mithrix

The head of the Mithril Cartel keeps a goblin in all six starting areas, in his admiral's hat. Time is money, friend: he sells shortcuts and rare goods, never freebies. Everything he sells is a sink, like a repair bill: the Mithril is burned for good while the Vault of Undermine is well stocked, and otherwise goes back into it to pay everyone's loot.

Level boosts. Jump straight to level 20, 30 or 40. A boost teaches every spell your class and weapon trainers would teach up to that level, the class quest spells (stances, pets, forms, totems) and maxes your weapon skills. The level 40 boost also teaches riding and hands you your race's level 40 mount.

BoostPrice
To level 201,500,000 MITH
To level 304,000,000 MITH
To level 408,000,000 MITH

He only offers boosts above your level, 40 is the highest, and he asks "Pay 1,500,000 Mithril?" before any Mithril moves.

A continent: every flight path and the whole map. For 500,000 MITH, learn every flight master of your faction on the Eastern Kingdoms or Kalimdor, as if you'd flown to each one, and get the Cartel Atlas: that continent's whole world map, revealed. Exploring still gives its experience, and the fares are the flight masters'. Offered until you own that continent's map, at any level.

The Cartel Courier. For 500,000 MITH, once per character: click the mail icon on your minimap to open your mailbox anywhere in the open world. Not in combat, while dead, on a flight path or inside a dungeon, raid or battleground. The icon stays on your minimap, bright when there's mail.

The Cartel's rare goods. Things that are hard to find: rare reagents, world-drop recipes and a few world-drop epics, never dungeon loot. Stock is limited and refills over the day.

ItemPriceStock per day
[Black Lotus]2,500,000 MITH3

[Hand of Edward the Odd]25,000,000 MITH1
[Krol Blade]15,000,000 MITH1
[Kang the Decapitator]8,000,000 MITH1

The Cartel charges a premium over the auction house, so farming and selling these yourself still pays. A vendor buys any of them back only at its normal price.

Prices are realm settings; his menu always shows the current one.

Cartel quests

The Cartel's First Job

The first time a wallet's first character enters the world, the Exchange goblin in front of you has a job: bring 3 Cartel Markers from the critters around the start, about a minute and a half. You stay put until you take the quest. Markers are party loot, so a group gets one each per kill.

At the turn-inAt level 10
Cartel Founders, the first 300 wallets200,000 MITH600,000 MITH
Every wallet after them5,000 MITH20,000 MITH

The level-10 part can be spent at once and leaves for your wallet from level 20. Founders also get a founder number and, after their first withdrawal, the Cartel Founder's Tabard. Any wallet takes its founder spot at the turn-in while spots are left, a brand-new one included. The details: Getting started.

The Big Score

The Mithril Cartel has a job, and it pays. The Big Score is a six-step questline, levels 10 to 35, for both factions. Trade Prince Mithrix and the Cartel Fixers in Ratchet, Booty Bay and the Hillsbrad Foothills crossroads hand it out, one step at a time as you level. The Venture Company stole something of the Cartel's, and the Cartel would like it back, plus whatever else is in their vault:

StepLevelReward
Hostile Takeover10Serve a "completely legal" eviction notice to a Venture Co. foreman, in the Barrens or Loch Modan.400 MITH
Industrial Espionage18Put on a Venture Co. peon uniform, walk into Windshear Crag in the Stonetalon Mountains, steal the blueprints. Look busy.1,500 MITH
Insurance Fraud23Blow up a Cartel warehouse (an empty, very well insured one) in Ratchet or Hillsbrad.2,000 MITH
The Inside Man28Get a Venture Co. accountant out of Windshear Crag alive. He'll complain the whole way.2,600 MITH
Honor Among Thieves33Take the vault code from the Bloodsail pirates at Lake Nazferiti in Stranglethorn Vale.3,000 MITH
The Big Score35Fly the Cartel zeppelin to Cartel Island and crack the vault. Alone.5,000 MITH and the Made Goblin's Tabard

The finale is solo: no groups, and nobody else can fight it for you or heal you while you're inside. It's built for any class at level 35 in normal gear. Cartel Island is invite-only: without the quest, you're sent home.

The race. The first wallets to finish win a prize, paid once:

PlacePrize
1st20,000,000 MITH
2nd to 10th2,000,000 MITH each
  • The first finisher is announced to the whole realm, and every Cartel goblin sets off fireworks. The first ten go on the Hall of Fame plaque on the island.
  • One place per wallet; game master accounts don't count. You need a linked wallet to claim; signed in with Phantom, you have one.
  • Prizes are paid like any other Mithril, so they show on the public ledger and can go to your wallet like the rest.

What's in the vault? Get there and find out.

A Mule for the Road

From level 20, at Trade Prince Mithrix: 10 Wool Cloth and 250,000 MITH for the Cartel Pack Mule.

Launch weeks

The starting areas get crowded at launch, so for the first weeks:

  • Faster respawns where it's busy. Ordinary mobs below level 20 in the open world respawn faster when four or more players of their level are nearby: 6% faster per extra player, up to 75% faster, and never under 30 seconds. A Young Wolf's 3 minutes becomes 45 seconds with 16 players around.
  • Faster quest spawns. Eight lone named quest mobs (the Agamands, Ivar the Foul, Vejrek, Vorlus Vilehoof, Oakenscowl) respawn in 60 to 90 seconds, and six looted quest objects (Milly's Harvest, Fel Cones, the Well Stone, Ambercorn, Shimmerweed baskets, the Stolen Books) in 30 to 45.

Both scale back once the crowds thin out, and at the latest two weeks after launch.

Keeping it fair

Spam gates for new characters

Below levelYou can'tExcept
5Whisper strangersReplies within 30 minutes to anyone who whispered you, and friends, group and guild
5Talk in General, Trade, LocalDefense or LookingForGroup, or /yellYour own custom channels; /say works from level 1
5Open a trade with a strangerAccepting a trade always works; friends, group and guild
10Send a letter without an item or at least 100 Mithril attached

An account with a level 20 character skips the level 5 gates.

The anticheat

The realm checks every move against what's possible. Nothing bans; a cheat gets you disconnected.

DisconnectsLogs for review
Speed hacks, teleports, flying, wall climbing, water walking, slow fall and hover hacks, moving while rooted, jump hacks, falling without taking damageMovement-clock mismatches, which the browser client can trigger by itself (until its clock fix ships), and a few checks that need a person to judge

It was tested against honest play first: walking, mounts, the travel pace, summons, Charge, Blink and the freezes a browser tab can have are never flagged.

Accounts and money

  • New accounts per network: 2 a day and 5 a month per internet address. Wallets that already have an account always get in.
  • Money between players needs a wallet: trading, mailing or bidding Mithril needs an account linked to a wallet, which every Phantom sign-in is.
  • Logins wait for money in flight: if Mithril reaches an offline character (a withdrawal or deposit from the website), logging in waits on the loading screen a few seconds instead of failing.

Fixes vanilla servers still have

  • Master loot can't hand out the same item twice. A dupe inherited from the server core; fixed, and shown fixed by a test that reproduces it on the old build.
  • Drain Soul no longer crashes the server when the warlock has changed maps.
  • The test realm's tools are off. The old test helper's free levels, items and Mithril are switched off for every account, and the developers' sandbox map is closed.

Built, not switched on yet

  • Buying and selling Mithril for SOL at the Exchange goblin and Mithrix: built and tested, not switched on yet.
  • The Goblin Market, the auction house on the web: see Auction House.

Anything further out is on the Roadmap.
