(Live Now) Hearthstone 25.0 Patch Notes – March of the Lich King Launch, Death Knight Prologue & Launch Event, Constructed, Battlegrounds, Duels, Mercenaries & Arena Updates, Bug Fixes & More

Update: The patch is now live on both PC and mobile – enjoy!

Patch 25.0, March of the Lich King pre-patch, launches tomorrow (November 29). While the main focus is Constructed (and the biggest card launch ever), it adds something to all of the game modes. Here’s a summary of what’s coming:

• March of the Lich King – New expansion launches on December 6, alongside Path of Arthas set and new Death Knight cards in Core Set + other things like Undead & Dual minion types. You can check out our full expansion guide here to learn more.
• Signature Cards – New cosmetic card type is launching. They can be opened either in normal card packs (at the rate of Golden Legendaries), or in new Signature Card Packs at a much-increased rate. While they can’t be disenchanted, they offer another kind of duplicate protection – if you get one for a card you already own, you can reroll that card into something else.
• Death Knight Prologue – In order to unlock the new Death Knight class, you need to play through a single player Death Knight Prologue launching with the expansion (December 6). You get 32 Core Set Death Knight card for completing it.
• Death Knight Launch Event – With the Hallow’s End event behind us, we’re getting the second official event in the new system, this time for the launch of Death Knight class. Rewards for the event seems to be 6x Signature Card, 1x Card Pack and 1x Cosmetic Card Back. We’ll also have another event later in this patch, called Winterveil event – more details will drop later (probably shortly before Christmas).
• Constructed Update – Two cards are getting nerfed – Theotar, the Mad Duke (goes up to 6 mana and 4/4 stats) and Ice Revenant (now gains +1/+1 instead of +2/+2 for every Frost spell).
• Battlegrounds Updates – Small BG update, the mode gets a new Hero & new Quest reward.
• Mercenaries Update – Another small update, with one new Mercenary added (Chromie). Chromie will be obtainable on Patch 25.0 rewards track.
• Duels Update – A big update to the Duels game mode, with two new Death Knight Heroes, new Treasures, as well as a revamp to how card buckets work.
• Arena Update – Dual-class Arena is gone and we’re getting a new rotation. Death Knight class will be added to Arena with drafting update – as you pick cards, what you’re offered will be automatically adjusted based on the Runes you picked (so you follow the normal Runes deck building rules).
• Improved Duplicate Card Handling – We already covered it in a separate post, but we’re getting some changes to how duplicates of cosmetic cards are handled. For example, if you already own a regular version of X Legendary and then get a Diamond copy, you will get an option to reroll the regular version into another Legendary from the same set. Read more here.
• Bug Fixes & Game Improvements – Just like every big patch, it comes with a multitude of bug fixes and other small improvements (however, just like always, it will probably break a lot of stuff too, especially with the release of a new class, so stay tuned for our Patch 25.0 Known Issues post).

Patch 25.0, launching tomorrow, rallies the troops for Hearthstone’s newest expansion, March of the Lich King, launching December 6! This patch also includes updates to Battlegrounds, Mercenaries, Duels, and Arena, as well as bug fixes and more.

March of the Lich King Launches on December 6!

Hearthstone’s next expansion, March of the Lich King, sets off on December 6! The new expansion includes 145 all-new cards, featuring the new Death Knight class, dual-type and Undead minions, the new Manathirst keyword, and more! See all the new cards in the official card library today, and don’t forget to get your pre-purchase bundle—this time, available until up to one week after expansion unlock!

The Mega Pre-Purchase Bundle is entirely focused on the Hearthstone mode this time, granting more cards than ever before, including Signature cards, Signature Packs, and the entire 49-card Path of Arthas set!*

* Path of Arthas includes 26 distinct Death Knight cards (2 copies of each, except for 1 copy of each of the 3 Legendary cards) that are not part of March of the Lich King and can’t be opened in packs. In addition to being included in the Pre-Purchase Mega Bundle, Path of Arthas cards can be crafted or purchased as a complete set after the expansion goes live.

With the launch of March of the Lich King comes a new Rewards Track with tons of cosmetics, XP boosts, packs, and a huge infusion of Gold! Check out our Rewards Track Refresh blog for details.

Undead Invade the Tavern

A new minion type has been added with March of the Lich King, Undead! Hundreds of minions from past card sets have been given the new Undead type, along with an army of minions in this expansion. With the addition of Undead, we’ve also added Dual-Type Minions so that we can best capture the essence of these minions. Some past and new minions will now feature two minion types, such as Undead Dragons and Demon Pirates.

The Reborn keyword is making its return in March of the Lich King, and it will become a keyword we regularly use going forward. Minions with Reborn return to life with 1 Health the first time they die. Reborn is commonly featured on Undead minions, but you might occasionally see it on other cards as well.

Card Updates

Theotar, the Mad Duke

• Old: [5 Mana] 3 Attack, 3 Health
• New: [6 Mana] 4 Attack, 4 Health

Dev Comment: The release of a new class is an incredibly exciting moment for Hearthstone players everywhere, and a moment that we want to be as enjoyable and accessible as possible. Knowing the importance of this new class release, our plan with Theotar was to test out a smaller change to the card (from 4 to 5 mana in Patch 24.4.3) before potentially moving for a larger change if necessary. Theotar’s play rate did not drop as far as we would have liked it to with the smaller change, and is still higher than we would like it to be leading into March of the Lich King. Our aim with this second change is to lower the card’s play rate to ensure that the release of Death Knight is as fun as possible for players with a wide variety of interests and experience levels.

Ice Revenant

• Old: Whenever you cast a Frost spell, gain +2/+2.
• New: Whenever you cast a Frost spell, gain +1/+1.

Dev Comment: The nerf to Ice Revenant might appear out of place, but it feels like a necessary one in a world where Death Knight has access to multiple cheap Frost spells (like Horn of Winter). In testing, we were frequently seeing Ice Revenants at game-ending sizes as early as turn 4, and the card was simply overshadowing many of the new and exciting things in the set.

Signature Cards are Here!

Signature is a new cosmetic quality (like Golden or Diamond) that cards can have, starting with Patch 25.0, featuring full-art images! Signature cards can’t be crafted or disenchanted; they can only be opened in packs or obtained through special means. Two are included in the Pre-Purchase Mega Bundle, along with regular and Signature March of the Lich King packs that will give you chances to open more! Learn more about Signature cards and Signature packs in our Expansion Announcement blog and explainer post.

Death Knight Prologue Available December 6

Play through the iconic story of the haughty prince Arthas Menethil as he forsakes the Light and becomes The Lich King, Hearthstone’s first Death Knight! The prologue will show you the strength of the Death Knight as you explore its new Hero Power and three Runes: Blood, Frost, and Unholy. Complete the Death Knight Prologue to unlock the Death Knight class and immediately receive 32 free Death Knight cards, added to the Core Set.

Death Knight Launch Event Starting December 6

To celebrate the launch of the March of the Lich King, a special expansion launch event will be taking place using the new Events system. From December 6 to December 20, complete daily Event Quests to earn Event XP on a special Event reward track! Complete the Event rewards track to get 6 Signature cards (2 copies each of three non-Legendary cards), a March of the Lich King pack, and a special Card Back.

A Winterveil Event will be coming later this patch. Stay tuned for more details on that event in the coming weeks.

Tavern Brawl: A Lich King Recipe – December 7

The deck recipe brawl is back for March of the Lich King! Choose one of Hearthstone’s now 11 classes and play with a battle-ready Standard deck. But this time, there’s a twist! When you choose Death Knight, you will randomly play with one of three decks, each highlighting a different rune.

Battlegrounds Updates

The following updates will go live with Patch 25.0, on November 29.

New Hero

Enhance-o-Mechano (Armor Tier 1)

• Enhancification
  • Passive. After each Refresh, give a minion in Bob’s Tavern Taunt, Reborn, Windfury, or Divine Shield.
  • Dev Comments: The odds for each enhancification are equal (25%), except that a minion won’t be given a keyword it already has. So if ALL minions in a shop offering already have one of the keywords, it will roll something else.

This new hero will be available in all lobbies for two weeks after patch launch.

New Quest Reward

Enhance-a-matic: At the start of your turn, get an Enhanced Part that gives +5/+5 and a random bonus.

Enhanced Parts:

• Mega Horn: Give a minion +5/+5 and Taunt.

• Blazing Blades: Give a minion +5/+5 and Windfury.

• Bunker Plating: Give a minion +5/+5 and Divine Shield.

• Death Rewinder: Give a minion +5/+5 and Reborn.

Dev Comment: The odds for each of the Enhanced Parts are equal (25%).

New Mercenary

Duels Updates

General Updates

• On November 29, there will be a major change to how Duels card buckets function (discussed below).
• On November 29, March of the Lich King, Path of Arthas, and Knights of the Frozen Throne will be added to the Duels card buckets (subject to the new buckets logic). At the same time, Knights of the Frozen Throne will also be added to deckbuilding.
• On December 6, the current Duels season will end, ratings will be reset, and ongoing runs will be concluded.
• On December 6, March of the Lich King and Path of Arthas will be added to deckbuilding and the two new Death Knight heroes will be added to the hero pool.
• Death Knight deckbuilding rules will apply to the initial Duels deckbuilding phase, just like the Hearthstone mode.
• You are not required to complete the Death Knight Prologue to unlock the Death Knight heroes in Duels. However, you won’t have the Death Knight Core Set available to you in deckbuilding if you haven’t unlocked the class. If you don’t have any Death Knight cards, you will only be able to use Neutral cards in your deckbuilding.

Card Bucket Revamp

With Patch 25.0, the Duels card bucket system will be getting a major update. The “Group Learning” bucket will be removed entirely. All other buckets will be adjusted to give cards by expansion, instead of by grouped type of effect. Cards for buckets will be generated based on cards from your deck, then a bucket will be generated based on the associated bucket pool.

Additionally, Death Knight will be added as a playable class in Arena. When playing as a Death Knight, Arena deckbuilding will dynamically update as you pick cards so that the Death Knight Rune system is followed.

* As a reminder, Knights of the Frozen Throne will be rotated back out of the Core Set with the launch of March of the Lich King.

New Feature: Improved Duplicate Card Handling

We often include specific non-disenchantable cards as part of Reward Tracks, Events, Achievements, and Shop purchases. Starting with 25.0, if you claim one of these, but already own a lower quality copy that’s disenchantable, you’ll get a popup that offers to re-roll the lower quality copy to a different card of the same rarity from that card set.

For example, Diamond Grand Magister Rommath is on the March of the Lich King Tavern Pass. If you already own a Golden Rommath when you claim the Diamond, you’ll immediately get a popup offering to reroll Golden Rommath into a different March of the Lich King Golden Legendary (which, of course, respects duplicate protection). This feature also applies when you find a Signature card in a pack!
