Warcraft Rumble Advanced Rulebook

The user interface of Warcraft Rumble emphasizes visuals over numbers. This page is an attempt to document the mechanics and functionality of the game in more detail than the client provides.

This page approaches the topic from the perspective of mechanics and features. Individual minis are occasionally discussed, and you can find more mini-specific details from the accompanying Warcraft Rumble Advanced Mini Details as well as from our individual Mini pages.

Rulebook Contents

Buildings and Map Objects

Barracks

The main base of a player.

• 3500 health (4300 health in Raids, 5400 health in PvP)
• 9 range
• 1.5 seconds attack speed
• Fury
• 70 Physical damage
• Vulnerable to Siege damage (+100% Siege damage taken)
• Dragon Barracks and Rocket Barracks have attacks identical to Dragon Tower and Rocket Tower

Barracks take half damage from most spells:

• Arcane Blast
• Blizzard
• Chain Lightning
• Earth and Moon (Starfall)
• Eclipse’s Moonfire (Sunfire deals even less)
• Holy Nova
• Living Bomb

Eclipse’s Sunfire deals less than half damage to Barracks, 150 damage, whereas it deals 400 damage to minis.

Deep Breath, on the contrary, deals additional damage to Barracks (200 damage and the Burn effect). This is probably a mistake, as the Barracks damage was not changed when Deep Breath was nerfed.

Execute deals damage equal to 5 percent of Barracks health at even level. The level modifier is 1 percent.

Banshee cannot possess Barracks, but will apply a damage-over-time effect instead. It deals 10 Elemental damage every 0.1 seconds for 10 seconds, for a total of 1000 damage.

Guard Tower

The regular Tower.

• 1600 health
• 9.5 range
• 1.3 seconds attack speed
• Fury
• 70 Physical damage
• Vulnerable to Siege damage (+100% Siege damage taken)

Minis that can outrange Guard Towers:

• Meat Wagon (range 11, range 13 with Filet Trebuchet talent)
• Plague Farmer with Splashing Pumpkins talent (range 10)
• Sylvanas with Queen’s Reach talent (range 10.2) - Sylvanas can always hit a Guard Tower from outside its range, but there needs to be something directly on the path to make her attack without the talent
• Flamewaker can hit a Guard Tower from outside its range, but Flamewaker only attacks when it has a target within a range of 7.5, so there needs to be a mini in front of the Tower

Dragon Tower

Tower with an elemental breath attack.

• 1600 health
• 9 range
• 2.4 seconds attack speed
• Up to 4.5 range: 5 ticks of 80 Elemental damage, for a total of 400 damage
• Up to 9 range: 5 ticks of 8 Elemental damage, for a total of 40 damage
• Vulnerable to Siege damage (+100% Siege damage taken)

Rocket Tower

Tower with a piercing rocket attack.

• 1600 health
• 14 range
• 3 seconds attack speed
• 160 Piercing damage on a radius of 4
• Vulnerable to Siege damage (+100% Siege damage taken)

Gold Mine

The standard gold respawn time is 30 seconds.

Treasure Chest

Contains 2 gold. Treasure chest has 220 health.

The standard treasure chest respawn time is 40 seconds.

The contest radius of chests is 9. This means that some minis (such as Plague Farmer with Splashing Pumpkins talent and Meat Wagon) can open a chest even though they are not in range to contest it. If an enemy mini is within a radius of 9 when that happens, they will claim the chest instead.

Chests can only be claimed by ground minis: knocking back minis around a treasure chest causes them to bounce upwards, which makes them ineligible to contest the chest. In practice, you can claim a chest even if the enemy also has minis around it if you can knock them back, even if they remain within range of the chest.

Deploy Zones

Lane splitting

• When you play a squad mini on the line between two deploy zones, the squad will split up with some of the minis heading for each lane.

Mechanics

Damage Types

There are four types of damage in the game.

Physical damage that can be mitigated by Armored.

Siege damage that is like physical damage, but also deals double damage to buildings. It can be mitigated by Armored.

Elemental damage that can be mitigated by Resistant.

Piercing damage that cannot be mitigated. This is not a separate damage type in the game files. Instead, there are two ways damage can be Piercing: either it is specifically configured to ignore any type of armor (such as Rocket Tower missiles) or it is a percentage-based effect (such as Execute). Currently, percentage-based effects cannot be mitigated.

Execute has a unique damage model. Its damage is a percentage of the target’s maximum health.

• Most targets: 50% with a 5% level modifier, minimum 5%
• Bosses: 10% with a 1% level modifier, minimum 1%
• Barracks: 5% with a 1% level modifier, minimum 1%
• Raid bosses: 3% with a 0.5% level modifier, minimum 0.5%

Gold Income

Players gain 0.330078 gold per second (it takes roughly 3 seconds to gain one gold). During overtime, the gold income is doubled.

Additional gold is available from mining and from opening chests.

Players start the game with 7 gold.

Each PvE boss has a gold income of their own and it also varies by game mode. Blizzard uses the gold income of bosses to adjust their difficulty.

Level Scaling

Mini power in Rumble scales with levels. Each additional level multiplies the values (health, damage) from the previous level by 1.100098 (roughly +10%).

Because the scaling is exponential, all level differences have the same effect, regardless of the absolute levels. A level 29 facing a level 30 (-1 level) is the exact same as a level 9 facing a level 10 (-1 level).

Values are usually presented as level 1 values for clarity. Comparing a level 1 value to a level 2 value gives the same answer regarding hits needed to kill a mini and so on, as comparing a level 23 value to a level 24 value.

Pushing and Collisions

Minis can bump into each other, block each other, and even push one another. Pushing is sometimes used to help a slower mini get into action faster. You can also gather faster minis behind a heavy mini that prevents them from passing.

The addition of Dryad with Nature’s Swiftness talent, which can make minis Fast, has made pushing strategies largely obsolete, but the physics for it still remain in the game. Raptors were often used for pushing in the past because of their speed and the fitting shape of their collision model.

Minis have weight, which affects their interactions with other minis. Heavy minis are more difficult (often practically impossible) to push than light minis. The vast majority of minis actually weigh the same, 100, but there are exceptions.

PvE Boss Functionality

PvE bosses play by the same rules as the player. They have a defined deck from which they draw minis to their hand, and they can only play minis that are in their hand. They must also have enough gold to play their minis.

There are two rulesets for opening hands: either the hands are reshuffled for each attempt (Dungeons, Raids) or the hands are shuffled once and then stay the same until you win (Campaign). This applies to both the player and the boss.

Blizzard has several tools that they use to adjust boss balance separately for each encounter:

• Starting gold
• Hand size (bosses can hold fewer or more minis than the player)
• Deck size (Heroic Bolvar has the smallest deck in the game, only 4 minis, and he can play any of them at any time. More commonly, the boss’s deck and hand size are similar to the player’s)
• Gold income (most bosses have a lower income than the player)
• Map mechanics, such as timed or conditional spawns and various phases

Targeting

The most common targeting method for abilities is the closest eligible target, and a mini usually keeps the same target until the target dies or moves too far from the mini. However, there are several other ways abilities can work in the game.

Stun effects reset a mini’s target, so a mini always acquires a new target after even a brief stun.

Lowest distance. The most common targeting mechanic. Mini targets the closest eligible target. This is what makes Whelp Eggs and Quilboar combo work: a boss targets Whelp Eggs, and when a Quilboar is played closer to the boss before the Eggs are popped, Quilboar becomes the closest eligible target and the boss will switch to it now that its old target - the Egg - is dead. This leaves the Whelps free to shoot the boss in the back.

Lowest current health. Mini chooses the target based on the lowest current health total.

• Chimaera Lightning Ball
• Priestess Power Word: Shield
• Witch Doctor

Highest current health. Mini chooses the target based on the highest current health total.

• Chimaera Poison Spit

Lowest maximum health. Mini chooses the target based on the lowest maximum health total.

• Abomination Hook
• Arthas Death Grip talent

Lowest turn angle. Mini chooses the target based on the smallest amount it has to turn to hit it.

• Angry Chickens Walking Crate talent
• Footmen Shield Bash talent
• Kashoch (campaign boss)

Highest health percentage. Mini chooses the target based on the highest current health percentage.

• Dryad Barrage talent
• Emperor Thaurissan Incinerate talent

Lowest health percentage. Mini chooses the target based on the lowest current health percentage.

• Priestess Renew
• Shaman Chain Heal
• Skeleton Party 5-Man talent Priest
• Tirion Holy Light

Highest health missing. Mini chooses the target based on the most missing health.

• Priestess Greater Heal

Do not retain target. Mini chooses its target each time it attacks based on its targeting mechanic. This can be the same target, if it is still the best match.

• Chimaera Lightning Ball and Poison Spit
• Dryad Barrage talent
• Emperor Thaurissan Incinerate talent

Abilities and Traits

Ambush

Double damage when attacking from Stealth.

Most multipliers in Rumble are additive (+100% and +100% combine to +200%). However, Ambush is implemented as a different attack with a higher base damage, and therefore it is multiplicative when combined with other damage modifiers (+100% from Ambush combined with +100% from somewhere else amounts to +400%).

Stun prevents a mini from acting. After recovering from a stun effect, a mini chooses a new target. Even a brief stun forces a mini to retarget, which can be beneficial or harmful, depending on whether you want the mini to keep hitting its previous target.

Stun effects do not stack. A longer stun effect replaces a shorter stun effect.

Raid bosses and Unstoppable minis are immune to stun. Bosses are affected by a shorter stun than regular minis.

Surge

Surge minis spend all of your gold when played.

If you put a Surge mini into a Charlga deck, then one of the costs in the cost pile will be to spend all of your gold. This can be difficult to notice and you need to keep an eye on whether the cost of the current mini or the next mini changes as you gain or spend gold.

Minis with Surge:

• Ancient of War
• Treant

Taunt

Taunt forces nearby minis to attack the caster.

The interaction between Vulnerable and Resistant is additive: a mini with Vulnerable (+100%) and Resistant (-50%) still takes an additional +50% Elemental damage.

Experience, Levels, and the G.R.I.D.

Activity Tracker (Daily Rewards)

Activity Tracker is the official name of the three daily rewards that you see in the Map tab below the map and above the Quest and PvP buttons. These rewards have to be earned each day, because unearned rewards do not carry over to future days. Earned rewards can be claimed later, and the contents of XP Tomes are determined when opened, so you can get XP for newer minis by saving your Tomes. When you claim the rewards, all earned rewards are claimed; you cannot claim individual Tomes or Coin bags if you have earned multiple rewards.

To earn a reward from the Activity Tracker, you need to earn 3 points. There are 3 rewards each day, so you get all the rewards for a day by earning 9 points.

• 1 point for a Common (green) Quest
• 1 point for a Normal campaign mission
• 1 point for a Dungeon boss
• 1 point for a Normal event mission
• 2 points for a Rare (blue) Quest
• 2 points for a PvP win
• 2 points for an Arclight Surge map
• 2 points for a Heroic event mission
• 3 points for an Epic (purple) Quest
• 3 points for a Heroic campaign mission
• 3 points for a Raid boss
• 3 points for a Mythic event mission

Activity Tracker consists of multiple nested decks of rewards. For the rare rewards, it is so far uncertain whether the deck is progressed through in full (so you are guaranteed each reward over multiple cycles) or if a reward from the deck is randomly awarded. Given how decks work in most aspects of Warcraft Rumble, it is likely that you will get each item from the deck before a new one starts.

The basic Activity Tracker cycle consists of 6 days of rewards. Within the 6-day period, the rewards can come in any order. For example, you may get the Mega Reward at the end of one 6-day period and another at the start of the next 6-day period, thus getting them on consecutive days. If you miss a day, you miss the rewards for that day.

The 6-day cycle consists of the following days:

• 3 days of Modest Tome, random Family Major Tome, and either a Troop Choice (3/6, 50%), Leader Choice (2/6, 33.3%), or Rare Core (1/6, 16.7%)
• 2 days of Modest Tome, random Family Modest Tome, and random Family Major Tome
• 1 day of Mega Reward, random Family Modest Tome, and random Family Modest Tome

The Mega Reward can be one of the following:

• 300 Coins (12/44, 27.3%)
• 500 Coins (7/44, 15.9%)
• 1000 Coins (1/44, 2.3%)
• Mythic Tome (3/44, 6.8%)
• Mega Tome (3/44 for Leader Mega Tome and for each family Mega Tome, 24/44 overall, 54.5%)

Assuming that all of this works fully as decks, you can expect to get:

• A Rare Core once per 36 days
• 24 Mega Tomes over 264 days (averaging once per 11 days)
• 20 Coin bags over 264 days (averaging once per 14 days), of which one is the big 1000 Coins chest

Arc Energy Conversion

When a mini with max stars gains another star or a mini with max XP gains more XP, the excess is converted into Arc Energy.

• Troop star: 225 Arc Energy (2.5 Arc Energy per Coin on the G.R.I.D.)
• Leader star: 300 Arc Energy (2.5 Arc Energy per Coin on the G.R.I.D.)
• XP: 20 XP gives 1 Arc Energy (2.5 Arc Energy per Coin from Daily Offers)

You can always buy Arc Energy with Coins from the store at 5 Arc Energy per Coin (1000 Arc Energy for 200 Coins, 5000 Arc Energy for 1000 Coins, or 10000 Arc Energy for 2000 Coins).

Collection Level

Collection Level determines how much XP you get from various sources in the game. The maximum benefits are gained at Collection Level 50, although you gain minor level-up rewards for increasing your Collection Level beyond that.

Each Collection Level you gain gives a one-time reward of 50 Coins. Starting from Collection Level 55, you also get a Star Tome every 5 levels (55, 60, 65, and so on).

Each Collection Level requires 50 points, and you gain points from mini rarity and levels:

• +5 points for collecting a mini
• +5 points for each rarity level (Uncommon, Rare, Epic, Legendary)
• +1 point for each level

Therefore, you can get a maximum of 45 Collection Level points per mini (Legendary level 20).

Daily XP cap

There is a cap of 50,000 XP per day from campaign missions, quests, PvP games, raids, sieges, and rewards. After reaching the cap, quest and end-of-game XP for the remainder of the day is set at 0. The day resets at the daily reset.

Dungeons

Dungeons are the source of army bonus slots in the early game and the main repeatable source of Arc Energy in the late game.

Dungeon level is Leader-specific. Each Leader starts from dungeon level 5, and the dungeon gains levels each time you defeat it. From level 5 to level 22, defeating a dungeon gives the Leader more army bonus slots. After completing a level 22 dungeon, a Leader will have all army bonus slots at gold level (+3 levels for a mini that matches the bonus slot trait).

Level 23 dungeons are repeatable weekly with eligible Leaders for 100 Coins (150 Coins for owners of Arclight Booster) and 1200 Arc Energy per Leader.

Leaders can only enter a dungeon when it is their family week. You may need to wait several weeks for an opportunity to use a Leader in a dungeon.

When you enter a low-level dungeon, there is a catch-up mechanic: each clear of the dungeon can count as clearing up to the next 3 dungeons (with all associated rewards). This catchup mechanic lasts until the dungeon level is 2 levels below your average army level, rounded up.

Examples:

• Clearing a level 15 dungeon with a level 21.1 army (rounds up to 22) gives you rewards for clearing 15, 16, and 17, and offers a level 18 dungeon next.
• Clearing a level 18 dungeon with a level 21.6 army (rounds up to 22) gives you rewards for clearing 18 and 19, and offers a level 20 dungeon next. (two levels, up to 2 levels below your average army level)
• Clearing a level 20 dungeon with a level 21.9 army (rounds up to 22) gives you rewards for clearing 20, and offers a level 21 dungeon next. (no more catchup)

G.R.I.D Appearance Rates

The full G.R.I.D. logic has not been figured out, but several parts of it are known. Many things in the G.R.I.D. are determined by decks, which ensure a consistent rarity spread over medium sample sizes.

For new players, the G.R.I.D. will offer a wide variety of minis before becoming random.

Every time a part of the G.R.I.D. is refreshed, it offers at least 2 new items. For example, if you have only 1 mini on the bottom row at the daily reset, the new row will have 2 items on it.

Troop rarity - deck of 2000 troops

• 1889 Common (94.45%)
• 100 Uncommon (5%)
• 10 Rare (0.5%)
• 1 Epic (0.05%)

Leader rarity - deck of 2000 Leaders (uncertain if in use or if combined with Troops at Troop rarity rates)

• 1789 Common (89.45%)
• 200 Uncommon (10%)
• 10 Rare (0.5%)
• 1 Epic (0.05%)

XP Boost deck

• 9 Modest (69%)
• 3 Major (23%)
• 1 Mega (8%)

General appearance rates

• XP Boost: every 18 minis cycled, needs an empty space
• Leader: every 16 minis cycled, other Leaders may crowd out a specific one, in which case it is offered as soon as possible after
• Talent: every 14 minis cycled (assuming one mini with an open talent slot)
• Same talent you just saw: no sooner than after 34 minis cycled (if you have one mini with an open talent slot, you will not be offered the same talent twice in a row)

G.R.I.D. Gadgets

Gadgets return to your inventory if you do not use them after placing them on the G.R.I.D.

Rare-O-Matic turns the affected mini into a direct Rare, regardless of what it originally was. Rare-O-Matic cannot be used on talents.

Tinker’s Gems can be used with talents to give XP to the mini the talent is for.

Mini XP per level

The XP scaling is not linear, but it is also not a simple exponential function.

XP needed to reach level x (from previous level):

• Level 2: 2
• Level 3: 5
• Level 4: 10
• Level 5: 20
• Level 6: 32

• Level 17: 16250
• Level 18: 37500
• Level 19: 90000
• Level 20: 200000

XP needed to reach level x (cumulative):

• Level 2: 2

• Level 18: 73309
• Level 19: 163309
• Level 20: 363309

Mini Level, Base Level, and Bonus Levels

The level of a mini consists of its base level from XP, and bonus levels from army slot, rarity, and talents.

Base level: up to 20

Army slot bonus: Up to +4 (Diamond slot)

Rarity bonus: One per rarity level above common, up to +4 (Legendary)

Talent bonus: One per owned talent, up to +3 (three talents)

The maximum mini level in the game is 31.

In PvP, mini level is divided by three and rounded up:

• PvP level 2: Level 4
• PvP level 3: Level 7
• PvP level 4: Level 10
• PvP level 5: Level 13
• PvP level 6: Level 16
• PvP level 7: Level 19
• PvP level 8: Level 22
• PvP level 9: Level 25
• PvP level 10: Level 28
• PvP level 11: Level 31

Quests

Quest level is dynamic: they are always 2 levels below the average level of your army.

There are three Quest rarity levels:

• Common (green): 1x rewards, lasts for 30 minutes
• Rare (blue): 3x rewards, lasts for 24 hours
• Epic (purple): 5x rewards, lasts for 56 days

You get access to 20 new Quests per day, stacking up to 300. Quests that you do not complete do not count against your Quest limit. Therefore, it is possible to complete a larger portion of rare and epic quests.

Winning a PvP match rerolls your current Quest, if it is a common. Note that the new Quest may also be a common.

The army you have equipped when you get a new Quest determines the minis you are offered a Quest for: the options are the lowest-level mini from your army (based on the base level only, no bonus levels), a random mini from your army, and a random mini from your collection.

The Quest rarities you get are not completely random. Blizzard often splits random things into decks in Rumble. For Quests, there are 8 decks of 5 Quests each: 3 decks of 5 Commons, 4 decks of 1 Rare and 4 Commons, and one deck of 1 Epic and 4 Commons. This gives expected appearance rates of 87.5% Common, 10% Rare, and 2.5% Epic. The internal deck selection logic has not been fully explored though: in particular, the decks may be rerolled if not completed soon enough (within 48 hours), which can affect offering rates.

The XP you get for completing a Quest depends on your Collection Level.

These are the base values for a common quest (excluding the +20% lifetime bonus for Arclight Booster):

• Collection level 1: 6 XP
• Collection level 2: 10 XP
• Collection level 3: 14 XP
• Collection level 4: 18 XP
• Collection level 5: 22 XP
• Collection level 6: 28 XP

Rarity and Talents

Upgrading minis gives access to bonus levels and more talent slots. Purchased talents cannot be changed, you need more talent slots to be able to acquire different talents. Talents are offered randomly on the G.R.I.D., and you may see multiple talents for a mini before you find the one you want.

Only one talent can be equipped at a time. You can also unequip all talents from a mini by clicking the equipped talent in the selection screen.

Rarities, upgrade costs, and benefits:

Common

• The initial rarity level
• No talent

Uncommon

Time-limited Minis

Some minis are not always available to collect. Minis that are only available for a limited time can be used in armies at all times, you can get XP for them at all times, and talents for empty talent slots are always available.

However, gaining stars for time-limited minis is not possible outside of specific opportunities. They do not appear on the G.R.I.D. or in the Daily Offers. You can upgrade them to a new rarity level, if you already have the stars, but getting new stars is difficult or impossible.

Time-limited minis that have been released so far:

• Headless Horseman (Recurring during Hallow’s End event)
• Arthas Menethil (Split Leader)
• Malfurion Stormrage (Split Leader)
• Orgrim Doomhammer (Split Leader)
• Anub’arak (Split Leader)

Split Leaders have no confirmed return schedule. However, Split Leader stars are available in limited quantities from Split Leader Star Tomes. The only current source of these Tomes is Heroic Siege.

Even if you own a time-limited Split Leader, its stars will not appear during its family weeks. However, you can use it in the dungeon to earn Coins and Arc Energy.

XP Tomes

The experience gained from XP Tomes increases based on Collection Level. 5% of Tome pages give double experience.

G.R.I.D. and Daily Offer XP Gems are based on Mega Tome pages.

• Modest XP Gem: 1 Mega Tome page (5000 XP at Collection Level 50)
• Major XP Gem: 2 Mega Tome pages (10,000 XP at Collection Level 50)
• Mega XP Gem: 5 Mega Tome pages (25,000 XP at Collection Level 50)
