The Diablo 20th Anniversary Tavern Brawl: Release Date and Everything We Know

Warning: This article contains datamined information. Information presented here may change before launch.
Warning: The article contains spoilers. Enter if you dare! Moooo.

In the recent Hearthstone patch which brought Mean Streets of Gadgetzan to us, a new Diablo themed card back was discovered which was tied to an upcoming Tavern Brawl. This Tavern Brawl is called the "Dark Wanderer Tavern Brawl" and is going to be a part of the Diablo 20th Anniversary Celebration, something which will be celebrated among many of Blizzard's titles.

This post outlines everything we know so far about the Brawl.

Release Date - January 2017

Just like the other Diablo celebrations in Blizzard titles, this one will be running next January. But wait - there's more!

We believe the release date of The Dark Wanderer Tavern Brawl will be on Tavern Brawl Week 82, which should translate to January 4, 2017! Why do we believe this? What do you mean you don't blindly trust us? Okay, fine.

A file in the Hearthstone client which contains information on card backs has an interesting field called "DATA1". This field when used with seasonal card backs refers to the season number, and in other cases it simply remains 0. In the case of the Winterveil Card Back though, this was set to 27..

Why is 27 of interest? Well that's because the Gift Exchange Tavern Brawl was Brawl Week #27!

The DATA1 value in the CARD_BACK.XML file is 82. This means Brawl Week #82. So yeah, the DATA1 value when used with SOURCE field value of tavern_brawl refers to the first week the brawl will be active on. The More You Know!

Reward - Secret Level Card Back

Moo. That’s right. You heard me.

Like the Winterveil Brawl of 2015, you will likely have to win a match to get the card back.
