(Live Now!) Hearthstone 29.4 Patch Notes – Dr. Boom’s Mini-Set, Balance Changes, New Twist & Arena Seasons, In-Game Event, Bug Fixes

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

Blizzard just posted patch notes for the upcoming 29.4 update! The patch drops tomorrow (probably around 10 AM PT / 19:00 CET), and while the main new addition is the mini-set, we have some other cool stuff too. Here’s a summary of what’s coming in the update:

• Dr. Boom’s Incredible Inventions Mini-Set – Mini-set for the Whizbang’s Workshop expansion is released together with the patch. It will add a total of 38 new cards (including 4 Legendaries) and, just like always, should have sizeable impact on the meta. You can buy the regular version for $15 or 2000 Gold. Full golden version is also available.
• Standard Balance Changes – We have a couple of Standard balance changes. Deepminer Brann now costs 8 mana and Saddle Up! now costs 4 mana.
• New Twist Season – Whizbang’s Heroes – After 2 months without Twist, we’re finally getting a new season on June 1. And it actually looks quite promising. Choose one of the 19 Heroes with special Hero Powers, passive effects and unique, pre-made decks. Heroes are unlocked by owning a Legendary card on which they first appeared in Hearthstone. So, for example, in order to unlock Dr. Boom, you need to own the original Dr. Boom card from Goblins vs Gnomes. The good news is that 4 of the Heroes and 2 more were available as a free card in past expansions (so they can still be easily unlocked by simply buying one card pack from that expansion). It means that 6 out of 19 Heroes are readily available for F2P players. Additionally, in order to unlock a whole deck, you just need to craft a single Legendary card, so the format as a whole is much more accessible. More info will be provided closer to the season’s start in June.
• New Arena Season – A new Arena season launches and all of the current runs will be retired. As always, you can start a new Arena run and play until 2 loses, when it gets retired you keep all of the regular rewards and get a Tavern Ticket refunded. The new Arena season will still use the premade pool of cards, but now with the addition of the new mini-set cards. We’re also getting some changes to randomly generated cards – now they will only include cards from Ashes of Outlands (2020) and forward, so you will no longer be able to Discover or generate older cards.
• Dr. Boom’s Aisle Of Mischievous Toys – A new in-game event happens from May 21 to June 11. Earn six Whizbang’s Workshop card packs and a new Thunder Ape Shaman skin for participating.
• Weekly Quest Update – We also have a small update about the state of the Weekly Quests. Apparently, the updates didn’t make it into this patch, but they are planned for the next client patch (29.4.2). That should be within 2 weeks from now. I’m not happy that it took so long, but it’s good that the pressure worked. However, before judging them we first need to actually see them.
• Bug Fixes & Game Improvements – Just like every major update, 29.4 comes with a sleuth of bug fixes and smaller QoL stuff.

Check out the full patch notes below:

Patch 29.4, launching tomorrow, brings an explosive new mini-set, Dr. Boom’s Incredible Inventions, and more!

Incredible New Inventions!

Dr. Boom’s tired of everyone calling Whizbang the world’s greatest inventor. So he kept tinkering away in the basement until he came up with something bombastic, something Gigantic, something… INCREDIBLE!

The Dr. Boom’s Incredible Inventions Mini-Set has 38 all-new cards. Get them in Whizbang’s Workshop packs or as a complete 72-card* Mini-Set. Get the normal version for $14.99 or 2000 Gold, or get the all-Golden version for $69.99 or 10,000 Gold. The all-Golden version comes with a bonus Diamond copy of the Puppetmaster Dorian Legendary minion! You can see all the cards from Dr. Boom’s Incredible Inventions Mini-Set in the official Card Library.

* 4 Legendary cards, 1 Epic card (x2), 17 Rare cards (x2), and 16 Common cards (x2).

Gigantify Your Fun!

Dr. Boom’s Incredible Inventions include a new keyword: Gigantify! Gigantify is like Miniaturize, but bigger: whenever you play a card with Gigantify, you get an 8-mana, 8/8 Gigantic version added to your hand. That’s huge!

Hearthstone Balance Changes

Dev Comment: Our last balance update was a massive shakeup with over 35 changes, based on our general design philosophy and overall health of Standard. With so many changes at once, we built this extra balance window into this content patch to catch a couple power and playrate outliers that have cropped up since those changes. We still have our regular hotfix balance window planned for a little after this patch, once players have had a chance to play with the new mini-set cards and explore the new meta.

Deepminer Brann

• Old: [6 Mana]
• New: [8 Mana]

Saddle Up!

• Old: [3 Mana]
• New: [4 Mana]

Upcoming Twist Season: Whizbang’s Heroes

Twist is back with a huge, all-new season in June: Whizbang’s Heroes! In Whizbang’s Heroes, choose from exciting new Heroes, each with their own pre-constructed deck, Hero Power, and unique passive effect.

Each Hero is unlocked if you have their corresponding Legendary card (the first-appearance card with the same name as the Hero—except Illidan, who is unlocked by Metamorphosis in Core).

Whizbang’s Heroes will launch with 19 Hero options:

• Illidan Stormrage*
• Al’Akir the Windlord*
• Arch-Villain Rafaam*
• Leeroy Jenkins*
• Kael’Thas Sunstrider**
• C’Thun**
• Nozdormu
• The Lich King
• Xyrella
• Patches the Pirate
• Sir Finley Mrrgglton
• King Krush
• Forest Warden Omu
• Dr. Boom
• Zul’jin
• N’Zoth, the Corruptor
• Brann Bronzebeard
• Guff Runetotem
• Arfus

Keep an eye out for more details closer to the start of the June Twist season!

*These heroes are unlocked by cards in Core, so they will be automatically unlocked for all players at the start of the season.

**These two cards were free login rewards for older expansions. If not already unlocked, C’Thun is automatically unlocked by having a Whispers of the Old Gods pack and going to the pack opening screen and Kael’thas is automatically unlocked by having an Ashes of Outland pack and going to the pack opening screen.

Arena Updates

On May 14, all current Arena runs will end and a new Arena season will begin. The Arena rules and draft pools will remain the same, except that cards from Dr. Boom’s Incredible Inventions will be added to the pool. However, the random generation and Discover pools will be updated to only include cards from Ashes of Outland onward.

In-Game Event: Dr. Boom’s Aisle of Mischievous Toys

Dr. Boom’s inventions are, of course, incredible, but one or two of them have been known to… have a little extra boom. From May 21 to June 11, complete Event Quests to earn Event XP on the special event rewards track. Complete the rewards track to earn 6 Whizbang’s Workshop packs and the Thunder Ape Shaman Hero Skin.

Bug Fixes and Game Improvements

• Dev Comment: As we continue iterating on our progression system, and our communications around it, we’re working on some updates that didn’t quite make it into this patch. Our next Weekly Quest update is planned for the next scheduled client patch, Patch 29.4.2.
• [Hearthstone] Updated Photographer Fizzle to now load his Snapshot in existing hand order instead of timestamp order (meaning, for example, Mini cards will appear where they are in your hand when the Snapshot is taken, even though they were added to your hand later than other cards).
• [Hearthstone] Updated the order of Discover options in Illidan’s Gift to match the order on the card’s text.
• [Hearthstone] Fixed a bug where The Headless Horseman unfroze upon drawing Horseman’s Head (finding your head is nice, but your body’s still on ice).
• [Hearthstone] Fixed a bug where Open the Cages would not trigger off Observer of Mysteries before disappearing.
• [Hearthstone] Fixed a visual bug on some mobile devices where the enemy Secret zone overlapped and was difficult to see with hover. Fixed another visual bug on some mobile devices where the friendly Secret Zone couldn’t be hovered to see at all.
• [Hearthstone] Fixed a bug where Dr. Stitchensew could cause disconnects in rare circumstances.
• [Hearthstone] Fixed a bug where a Spell Damage Chia Drake wouldn’t have the Spell Damage effect when control was swapped or a copy was summoned.
• [Hearthstone] Fixed a bug where a Cosplay Contestant cosplaying as Magtheridon, Unreleased would trigger its Dormant effect twice each turn. That’s not canon!
• [Hearthstone] Fixed a bug where Fairy Tale Slime didn’t update its text from the opponent’s perspective.
• [Hearthstone] Fixed a bug where Spirit of the Badlands’s Mirage can create an extra, fake Mirage in hand—that was a bit too immersive.
• [Hearthstone] Fixed a bug where Crimson Expanse wouldn’t create an exact copy under certain circumstances.
• [Hearthstone] Fixed a bug where Felscale Evoker’s effect sometimes wasn’t tracking properly.
• [Battlegrounds] Fixed a bug where Battlegrounds Ratings were showing as stuck on 0 on tablet devices.

• [Battlegrounds] Fixed a bug where passing a minion to your partner while they were in the Choose One interface soft locked the client.
• [Battlegrounds] Fixed a bug where passing a minion to your partner while they are holding another copy of that minion, and the passed card forms a triple, blocks all functionality until the newly tripled card is played.
• [Battlegrounds] Fixed a bug where minions affected by Suspicious Stimulant couldn’t be passed from hand.
• [Achievements] Fixed a bug where the Tick, Tick, Boom! Achievement didn’t track properly after Boomboss Tho’grun’s effect was updated.
