Diablo returns: 30 Years of Terror runs to December 1
Hearthstone's Diablo crossover runs November 10 to December 1, with an event track that ends in a Dark Wanderer Warlock skin and a Dark Wanderer Tavern Brawl that closes on November 18.

Diablo is back in Hearthstone. Blizzard's 30 Years of Terror crossover started on November 10 and runs until December 1, with a returning Tavern Brawl, a free Warlock hero skin on the event track and a paid Diablo bundle in the shop. Everything below comes from Blizzard's 37.0 patch notes, which set out the event ahead of time.
The dates
- Event quests and Event XP: November 10 to December 1.
- The Dark Wanderer Tavern Brawl: November 10 to 18.
- The Diablo shop bundle: November 10 to December 8.
The Brawl is the shortest of the three. Its window closes about a week into the event, so if you want the pack it gives, play it this week.
The event track
Complete Event Quests to earn Event XP, and claim rewards as it builds up. Blizzard lists these rewards:
- 2x Treasure Fiend, one regular and one Golden
- 1x Golden Reign of the Black Empire Pack
- 1x Reign of the Black Empire Pack
- 1x random Rare card
- 1x random Epic card
- The Dark Wanderer hero skin for Warlock
Treasure Fiend is an Epic Warlock minion released for the event. You can look it up, with its current text, in the card library.
The Dark Wanderer Tavern Brawl
The Dark Wanderer Brawl comes back from November 10 to 18. You build a Wild deck and fight through a run of encounters that, in Blizzard's words, grows "more dangerous with every blow you strike". The last encounter is Diablo himself, once the Dark Wanderer's true form is revealed. Your progress carries over between attempts, so a loss doesn't send you back to the start.
The reward for finishing it is one Reign of the Black Empire Pack.
Because the Brawl uses Wild, any card you own that is legal in Wild can go in the deck.
The shop bundle
The paid part of the event is a Diablo bundle, on sale from November 10 to December 8, one week longer than the event itself. It contains:
- The Diamond Diablo, Lord of Terror hero skin for Warrior
- 3x Warrior Packs
- 5x Golden Standard Packs
- 2x Signature Epic Treasure Fiend cards
Blizzard's notes give the contents and dates but not a price here, so check the in-game shop for what it costs in your region.
What this means for ranked
Blizzard's event notes list no balance changes, so the most recent balance patch, 37.0.2, is still the one shaping ladder. The Hearthstone meta page shows the decks in Lolumen's tracked games, and the tracker logs your own.
