And why do you think so? I have an answer, but I’m not going to share it until we have some other ideas presented.
The hardest achievement is having to complete all the World of Warcraft achievements before playing Hearthstone. Kappa.
No frick that im not telling mine first, Do yours first
12 wins in a row by far.
Reason why is simple, the many enlighten users in this forum that say the game is rigged and prevents you from winning games.
I dont even understand how its possible to get that achivement, maybe you have to pay Blizzard or chill for them.
I dont know, but lord knows those people cant be wrong.
We say it’s rigged. Meaning it can rig you 12 wins bro!
I am the biggest believer in rig and i have the 11 win achievement when playing cycle rogue.
Ofcourse the rig they tried was to think i cared about achievements so they thought they could force feed me 11 and have a hunger for the 12th like an owner of a high stakes casino.
It rigged me 11 wins in a row and also rigged the last loss in an attempt to hook like n sinker me
Edit : looking back now i shouldve put my heart and soul into that 12th game but i was just playing, grinding, it was when my account was new anyways so it REALLLYYYY put me against low quality players
Anyone who played DH when it first came out probably got this easy snicker
Close, but that’s not the hardest.
Even I have that one.
Ozumat solo adventure. Kill all ozumats tentacles on the same turn. The boss is super unfair by itself the achievement is straight up impossible. Cards given are useless aswell, making this twice harder than any other achievement imo (since you can deckbuild on the rest).
That’s a tough one. I remember the exact day and deck i used to get it. I was playing that old Secret Paladin deck with the maul and secret sword and it used the murloc to fish out the 6 drop dragon. Went 13-0 in D5-Legend with it. I was floored how i just kept running over every opponent.
Closest i ever got to that was 2-3 Arena runs with 12-0 decks but that’s much easier to do than in constructed.
Spicey Pretzel Mustard in BG’s is a pretty tough one to get. I would like to know the % that have it. I got a few months back but it was by accident not even trying.
you have to mulligan for a very specific set of starting cards and then draw specific card sin the fight. It’s kind of dumb how it has to play out. there’s some guides online that show the order needed. A tough one for sure.
I have 20 in a row, a mystery for the ages since i trash Blizzard and the devs on a regular basis and never gave them a cent.
I did 12 in a row a few times already but my highest was with No Minion Mage when the class got Refreshing Spring Water.
I was really sad a couple days ago, as I was surprised to see the one for 11 pop up.
Lost to the final boss

I was really sad a couple days ago, as I was surprised to see the one for 11 pop up.
When i start winning more than a couple in a row i just stop counting.
The added pressure to make it to 12 makes me play like crap, i find it better to only check after i losse.
I also missed the mark before i got the achivement because of that, you are your own worst enemy.
Nothing my opponent does even comes close to my self sabotage when i try to force a win.
I want to say completing the card set collections, but i know thats biased.
Also have only focused on battlegrounds achievements since they were added. %99 currently. Currently just need a win with Reynor and the last few top finishes in dous.
Ill have to take a deep dive into the achievments list and come back with a more informed opinion.
I had 15 wins in a row before achievements with ransom priest. Still did’t get to legend with it.
Summoning 4 times the same adventurer with party up
You need to cast a 7 mana spell, now almost wild exclusively (which means a decent chance to not have the opportunity to cast it), and only have a 0.2% chance of getting the achievement
but also all 12-0 arena and (RIP) duels achievements

Ozumat solo adventure
It’s actually fairly doable, far from impossible, I’ve done it multiple times.
Where you are right though is that this achievement is, or at least used to be, buggued and was not granted properly.

all 12-0 arena
It’s actually Azeroth Gladiator, 12-0 runs with all 11 classes.
Someone posted that they had just completed it on reddit and Celestalon confirmed that they were the 13th person to get it. Thirteen. That’s it, the rarest achieve in the game.
Bah, beat me to it before I was able to respond.
Yeah that achievement is BS. Arena is the worst.

Rarity is helped by nearly nobody playing Arena…
I think more people play than you think, especially so in Asia servers.
