March 22, 2021

Today is a big day for fans of Blizzard games. Between the Overwatch experimental card notes and the new Hearthstone 20.0 patch notes, they should be set for a while.

Creating online TCG’s is not something easy to do. Maintaining one and keeping casual and hardcore players interested is even harder.

Luckily, Blizzard does just that and continues to keep fans coming back with each subsequent update to Hearthstone.

Today, we got the beefy Hearthstone 20.0 patch notes, so strap in because this is a big one. Here’s everything you need to know about what’s new in the Hearthstone 20.0 patch notes.

Hearthstone 20.0 Patch Notes

Here is the full list of patch notes for the Hearthstone 20.0 update:

Why Ratchet & Clank is the Most Important PS5 Game

Balance Update

Nitroboost Poison

  • Old: [Costs 1] → New: [Costs 2]

Dev Comment: We’re moving Nitroboost Poison to 2 mana to reduce the amount of cheap burst damage available in Rogue and create a real cost for Corruption. When evaluating Rogue’s future weapon-centric archetypes, we want to position the play patterns around building up a weapon over multiple turns and fighting for board rather than the hyper-aggressive strategies seen in decks like Stealth Rogue.

Nitroboost Poison will be eligible for a full dust refund for 2 weeks after the 20.0 patch goes live.

Battlegrounds Updates

  • Piloted Shredder has been removed from the Battlegrounds Minion Pool.

NEW HERO

Overlord Saurfang

  • For the Horde! [Costs 1]
    • Give +1 Attack to the next minion you buy this turn. (Upgrades each turn!)

Players with Battlegrounds Perks will have early access to Overlord Saurfang before the Hero is formally released on April 8.

NEW MINION

Barrens Blacksmith (Golden Watermark is not final)

  • [Tier 3] 3 Attack, 5 Health. Frenzy: Give your other Minions +2/+2.

Classic Format, Set Rotation, and the New Core Set

Ready for some nostalgia? The Classic format invites players to craft decks and compete using Hearthstone’s original 240 cards as they were in 2014, the year that Hearthstone launched! When the patch lands on March 25, your entire collection of relevant Basic, Classic, and Hall of Fame cards will be mirrored and available for deck building in the Classic format—as they were in the 1.0.0.5832 patch of June 2014 (after we made a few important changes), with any and all balance changes since then reverted. Classic packs will now add to your Collection for the Classic format, as well as the Legacy set in Wild. The Classic format leaderboards will launch on March 30. Read our announcement of the Classic format to learn more.

We’re celebrating the launch of the Classic format by rewarding all players with one Golden Classic Card Pack just for logging in after the 20.0 patch has gone live!

Set Rotation for the Year of the Gryphon will take place when Forged in the Barrens launches on March 30! Rise of ShadowsSaviors of UldumDescent of DragonsGalakrond’s Awakening, Demon Hunter Initiate, Basic, and Classic will be rotating to Wild. Replacing Basic and Classic in Standard will be the new Core Set comprised of returning, reimagined, and completely new cards! The full breakdown is as follows:

  • 88 cards returning from Classic (54 class cards, 34 neutral cards).
  • 52 cards returning from Basic (41 class cards, 11 neutral cards).
  • 55 cards returning from Wild (36 class cards, 19 neutral cards).
  • 4 cards returning from Ashes of Outland (4 Demon Hunter Class cards).
  • 4 cards returning from Demon Hunter Initiate.
  • 1 card returning from Hall of Fame (Shadowform).
  • 31 new cards (20 Class cards, 11 Neutral cards).

You might notice that the numbers for Basic and new cards have changed since we last shared the Core set breakdown. That’s because, after taking time to consider community feedback, we’ve replaced the previously announced Core set versions of Stonetusk Boar and Bluegill Warrior with two brand new minions—Emerald Skytalon and Redgill Razorjaw!

Lastly, we’ve updated the Shaman Hero power to replace the Wrath of Air (Spell Damage) Totem with a new totem, Strength Totem, which gives a friendly minion +1 Attack at the end of your turn!

The Great Unnerfing

We’re also reverting nerfs for 36 cards rotating to Wild! There are five days between when the 20.0 patch goes out and when these cards rotate so, we’re expecting the Standard meta to be very interesting this weekend. Watermarks on cards shown below are not final.

Spell Schools

Magical Spell Schools—Arcane, Fel, Fire, Frost, Holy, Shadow, and Nature—are being added to 545 previously released Spells across Standard and Wild as a permanent addition to Hearthstone with the patch on March 25! Spell Schools will add synergies and a new layer of depth throughout your Collection, and there are 24 more being added with Forged in the Barrens! You can find the updated breakdown below. For specifics, head over to the card library.

  • Arcane (2 Spells in Forged in the Barrens, added to 44 Spells from past sets)
  • *UPDATED* Fel (3 Spells in Forged in the Barrens, added to 23 Spells from past sets)
  • *UPDATED* Fire (2 Spells in Forged in the Barrens, added to 45 Spells from past sets)
  • Frost (2 Spells in Forged in the Barrens, added to 24 Spells from past sets)
  • Holy (5 Spells in Forged in the Barrens, added to 67 Spells from past sets)
  • *UPDATED* Shadow (4 Spells in Forged in the Barrens, added to 113 Spells from past sets)
  • *UPDATED* Nature (6 Spells in Forged in the Barrens, added to 117 Spells from past sets)

Rewards Track Refresh & Diamond Cards

When the Rewards Track refreshes for the first time on March 30, all players will automatically be granted any unclaimed rewards on both the free track and the Tavern Pass track if owned, and a completely new Rewards Track featuring a bevy of new unlockable loot will take its place!*

We’ve made several additional changes for the new Rewards Track in the 20.0 patch aimed at making in-game progression feel even better. In summary, we’ve doubled the number of core reward levels from 50 to 100 and halved the amount of XP required to reach each level. Where possible, we’ve also adjusted the amount of rewards at each level, in order to distribute them more effectively across the whole track. You can find the full table of rewards and specifics of how we’ve further improved the track here. Please note that incomplete Madness at the Darkmoon Faire Gameplay and Duels achievements as of March 25 will no longer grant Rewards Track XP, and instead a new set of Forged in the Barrens achievements will!

With the introduction of the Forged in the Barrens Tavern Pass, we’re excited to announce an all-new cosmetic card tier for Hearthstone: Diamond cards! Each expansion will include one or more handcrafted Diamond Legendary cards that feature completely new 3D animations, more real estate for card art, and a stylish Diamond border.

Blademaster Samuro and Bru’kan will receive the Diamond treatment in Forged in the Barrens! The unlock criteria for these cards are as follows:

  • Diamond Blademaster Samuro – Obtained instantly by purchasing the Forged in the Barrens Tavern Pass and claiming the card on the Rewards track.
  • Diamond Bru’kan – Obtained by completing the Forged in the Barrens Legendary Collector 5/5 Achievement (Collect all Legendary cards from the set.)

*Level 50 Hero skin choice must be made before the Forged in the Barrens Rewards Track refresh. Additionally, all players who are online at the time of the refresh will not see their Rewards Track immediately change over. These players must relog to receive the updated rewards track. We’re working to have the level 50 Hero skin automatically granted for those who missed claiming it and for the refresh to happen seamlessly for actively online players in a future patch.

Forged in the Barrens Tavern Pass

The Madness at the Darkmoon Faire Tavern Pass will expire with the launch of Forged in the Barrens and a new Tavern Pass will be made available for purchase—offering a host of brand-new cosmetic rewards and XP boosts.

Purchasing the Tavern Pass at any point during the expansion will immediately grant the Diamond Blademaster Samuro Legendary card, a 10% XP Boost that lasts for the duration of the expansion, and all items up to your current level on the paid track. As you progress with the Tavern Pass during the Forged in the Barrens expansion, you’ll earn additional XP Boosts, the Barrens card back, the uncraftable Shadowhunter Vol’jin Golden Legendary minion, the Firefang Rexxar Hero Skin, and an all-new cosmetic coin! You can also earn Hero Skins for the new Mercenaries introduced in Forged in the Barrens: three Rokara Warrior Hero Skins, three Kurtrus Demon Hunter Hero Skins, and three Xyrella Priest Hero Skins!

New Cosmetic Coins

There are three new Cosmetic Coins on the way, two of which are themed after Forged in the Barrens and obtainable by the following means:

  • Completing the first 90 levels of the Rewards Track with the Tavern Pass.
  • Collecting 135 unique Forged in the Barrens cards.

We are planning a 35 card Mini-Set for Forged in the Barrens, so that second Achievement will become much easier once there are 170 to collect in total! We’ll have more information to share on the Forged in the Barrens Mini-Set in the coming months.

We’ve also added a Bigglesworth Coin for collecting one of every card from Scholomance Academy. Collect all 135 cards from Scholomance Academy and this new coin will be yours!

Book of Mercenaries Rokara

Forged in the Barrens introduces 10 all-new Mercenary characters as Legendary minions! We’ll be telling the stories for these characters over the course of the year through our expansions, our website, the Hearthstone Mercenaries game mode, and through Book of Mercenaries!

Book of Mercenaries will tell an epic, serialized story featuring all 10 new Mercenary characters and will release on a semi-monthly basis like Book of Heroes. Book of Mercenaries Rokara, the first installment in the series, will release on April 6 and reward a Warrior class pack for its completion!

March 30 – Arena Rotation

When Forged in the Barrens launches on March 30, the Arena will include cards from the following sets:

Bug Fixes & Game Improvements

  • Fixed a visual bug where parts of the Zhuge Liang Anduin and Diao Chan Valeera Hero Skins were not appearing animated.

What’s Next for Hearthstone

Obviously, the Hearthstone 20.0 patch notes are really lengthy, so hopefully, players are satisfied for the time being. That said, people always want more, luckily, as Hearthstone is a Blizzard game, they’ll surely get more in upcoming fixes, rebalances, and updates soon. Blizzard is known for how often they update and rebalance their games, so you can probably expect some sort of hotfix or update in addition to the 20.0 patch relatively soon. If I had to guess, it wouldn’t be anywhere close to as extensive, but it might make some small rebalances or fix some bugs.

For more Hearthstone, make sure to stick right here with DualShockers.
