20.2 Patch Notes – Quilboars & 3 New Heroes in Battlegrounds, Duels Humble Blessings Nerf, New Hero Skins, Diamond Ragnaros And More – May 4

20.02 Patch Notes have just dropped and it’s huge! The patch releases on May 4 and here’s a roundup on all changes and new features:

  • 3 New Heroes (Death Speaker Blackthorn, Vol’jin, Xyrella) + 1 Hero Update (The Rat King) in Battlegrounds.
  • Quilboar minion type added to Battlegrounds – 17 new minions with a new “Blood Gem” mechanic.
  • Quilboar minion type also added to other formats, including Constructed – but there are no plans for any extra synergies for now. However, adding a new minion type alone affects some cards – e.g. N'Zoth, God of the Deep.
  • Humble Blessings got nerfed from 3 to 4 mana in Duels.
  • Diamond Ragnaros is out, and it’s a reward for collecting all 36 Classic Legendaries.
  • 10 new Hero portraits were added (one for each class) – they’re a reward for an achievement tracking your total rewards track level across multiple expansions. For each tier (every 200 levels), you get to pick one skin.
  • Battle-ready decks will launch too – learn more about them here.
  • Book of Heroes for Thrall is coming on May 25. The rest of Book of Heroes will probably release interchangeably with Book of Mercenaries.
  • Lots of bug fixes.

The 20.2 patch, which will release on May 4, includes a major update for Battlegrounds, purchasable decks, and more!

Battlegrounds Updates


Quilboar have been added as a new Battlegrounds minion type! There will still be five minion types per Battlegrounds game once Quilboar are added, meaning that three minion types will be excluded from each game. Just like when Dragons, Pirates, and Elementals were added, Quilboar will show up in every Battlegrounds match until our next major content patch.


The Quilboar update includes 17 new minions, 3 new heroes, and a new mechanic: Blood Gems! Blood Gems are spells that give a friendly minion +1/+1. Some Quilboar give you Blood Gems, while others have special interactions when Blood Gems are played.

We’ve also added Battlegrounds support for your favorite Coin! As a reminder, you can set a Coin as your favorite by clicking on the Coin icon in the top right of your Collection.

Finally, prepare for a fresh playing field as all players’ Battlegrounds ratings will be reset to 0 when the 20.2 patch launches on May 4!

    Patch is live but seems I cant claim any “tavern regular” portrait, even though I have completed the first level. Anyone else with this issue?

    It is interesting that 100 lvl Rewards Track Hero Portrants are based on the WoW Tier 1 sets (https://ru.classic.wowhead.com/guides/classic-wow-tier-1-molten-core-set-overview) and the new ones show Tier 2 sets (https://ru.classic.wowhead.com/guides/classic-wow-tier-2-blackwing-lair-set-overview).

    Looking forward to see T5 sets:)

    what if I have all the award already for classic but I disenchant some since (I think I’m currently missing 5 legendary)? Do I have to recraft those?

  4. JoyDivision

    Sooo … I checked the Classic Achivement and I’m missing 6 Legendaries …

    Went to my collection, checked ‘missing’ on ‘Klassikkarten’ (dunno the English word(s) for it; third one from the top in the filter list).

    Viewing my normal missing cards, those Legendaries are shown:

    Gelbin Mekkatorque
    The Beast
    Elite Tauren Chieftain
    King Mukkla

    Viewing Goldens, Illidan is shown (thought that card was replaced completely when DH became a thing); Chieftain and Gelbin aren’t shown then.

    So… to receive Diamond Rag, I need to actually craft Chieftain and Gelbin?? Those where promos back in the day, right?

    I’m a little confused, tbh.

    • Advocaat
      April 30, 2021 at 4:08 am

      Yes, you have to craft them. When I found out which classic legendaries I’m missing, I just gave up on diamond rag. I absolutely will not craft 10 totally useless legendaries to get it.

      • JoyDivision
        April 30, 2021 at 5:39 am

        Besides that, Rag doesn’t see play anymore so he is somewhat useless, too. 😉 But it’s DIAMOND RAGNAROS, so I’m not so sure I can withstand it’s … power. 😀

    • MJT3ll3r
      April 30, 2021 at 4:33 am

      You wouldn’t have to craft the special ones (gelbin and etc) but you have to craft gruul etc

      • JoyDivision
        April 30, 2021 at 5:33 am

        But it says I’m missing 6 … that number includes the promos. Well, if I decide to take that road, I might as well start with the other 4 and see if you’re correct. 😉

        • Mikek12003
          April 30, 2021 at 5:56 am

          i never crafted / opened promos still gotten the achievement. Will check to make sure

    For ragnaros if you aleardy finish the clasic achievement just have to click the achievement again or have to have again all legendary from clasic?
    For portraits the levs of the last expansion track count to the portrait?

    • MJT3ll3r
      April 30, 2021 at 4:32 am

      I assume you just have to click it again.
      I am wondering though for my case, i have the achievement but disenchanted Edwin after nerf. Would I have to recraft him or does the fact that I have the achievement suffice?

      • JoyDivision
        April 30, 2021 at 5:37 am

        A short while ago (regarding disenchanting that Battlescar-Dude), Stonekeep responded to me and told me that once you finished an achievement, it won’t be taken away if you disenchant afterwards. So my guess is you just have to ‘re-click’.

        Then again, it’s Blizzard we’re talking about, so who knows. 😉

    Will there be no balance changes for standard?

    Can’t wait to see the animations on the diamond Rag.

    Also I hope the next diamond card has taunt because the diamond taunt border looks SO COOL.

    • INeedHealing123
      April 30, 2021 at 9:06 am

      how do you know how diamond taunt looks? I dont think they made that yet

      • Noelle
        April 30, 2021 at 9:34 am

        You can give a diamond card taunt with stuff like Sunfury Protector etc. It looks really cool.
