(Update: Mercenaries Y’Shaarj Event Is Live Now) Hearthstone 23.4 Patch Notes

Blizzard has just dropped patch notes for the latest Hearthstone Patch 23.4. The patch drops tomorrow, presumably around the usual 10 AM PDT (19:00 CEST) time. While a new mini-set – Throne of Tides – is the biggest part of the patch for Constructed, it also comes with big updates to other game modes. You can find full patch notes below, but here’s a quick summary:

• Throne of Tides Mini-Set – A new mini-set is getting released with 35 new cards. You can buy it for $15 or 2000 Gold (alternatively, new cards will be added to Sunken City card packs).
• Mercenaries Update – Limited-time Y’shaarj event, 18 new Mercenaries (including one cross-promo with Diablo – Tyrael, who you can claim for free), new zone & bounties.
• Battlegrounds Update – New Hero (Ozumat), new minion (Bubblette) and Diablo returning for a limited time (only a week) as a cross-promo with Diablo Immortal.
• Arena Update – New Arena rotation, with some extra cards either retuning to the pool or getting banned.
• Book of Heroes: Faelin – The first PvE content after Book of Mercenaries. You can play a 17 missions long adventure as three characters – completing it with the first one will give players a Ghost Ship card back, second one a Standard pack and third one a Sunken City pack.
• New Feature: Overcapped Decks – Players can add up to 50 cards to their decks during deck building in order to make it easier. The deck won’t be legal until you go down to 30 cards, of course.
• Bug Fixes – Just like always, we’ve got a lot of bug fixes and small game improvements.

Mercenaries Updates

General Updates

• N’Zoth is now available through all normal acquisition means.
• You can now borrow a Party from your opponent in a Mercenaries friendly challenge.
• You can now copy a Mercenaries Party to build a new Party.
• A new option has been added to the Mystery nodes on Heroic Bounty maps. Whenever you land on a Mystery Treasure node, you’ll get additional rewards if you successfully complete the Bounty!  But beware, much of that treasure is Cursed, and will hinder your characters throughout the rest of your run. However, every once in a while your Mystery Treasure will turn out to be straight Bonus Rewards: all the additional prizes at the end of your Bounty without the added Curse! So… are you feeling lucky?

New Limited-Time Event: Y’Shaarj

Y’Shaarj watched enviously as N’Zoth sunk its tentacles into Mercenaries, so now Y’Shaarj, too, is coming to join the Party in its own limited-time event, starting on June 7. The event will consist of 10 special Tasks centered around the Old God Y’Shaarj. Two new event Tasks can be unlocked on each of the first five days of the event, but you have until June 21 to complete all 10 Tasks. Completing all 10 Tasks will get you the Y’Shaarj mercenary, a random Golden Y’Shaarj Portrait, the Diamond Y’Shaarj Portrait, and 750 total Mercenaries Coins. Humans and Pirates will be your best allies for this event!

Y’Shaarj and its Portraits will not initially be obtainable through packs or crafting. Y’Shaarj, its Portraits, and its Coins will all be obtainable through normal means in a patch after the event ends.

Despite many long years, Ambassador Faelin has never forgotten his youth in Zin-Azshari, an ancient city now in ruins at the bottom of the sea. When the opportunity to visit finally arrives, Faelin is eager to face any danger that may cross the path of his intrepid crew. But is the distant past truly as he remembered it, or did something darker lie beneath the surface all this time? This adventure can be played as three different characters. Completing all 17 missions the first time will grant the Ghost Ship card back; completing all missions with a different character will earn you a Standard pack; and completing all missions with the third character will earn you a Voyage to the Sunken City pack.

New Feature: Overcapped Decks!

Have you ever started building a deck and run out of slots before you even made it to the Neutrals? Now, when building a deck in “My Collection,” you’ll be able to add up to 50 cards as you tinker, and then trim it down to 30 when you’re done narrowing down your options. (You’ll still need to make a legal deck before playing with it). There’s no telling what you’ll brew up now that your limits are overcapped!
