Diablo 4 Season 15 Adds Secret Cow Quest, Whimsyshire

Diablo 4's Season 15, titled Hell's Legacy, launched two weeks ago and is packed with content pulled from the series' past. The season adds new dungeons, boss fights, and items from previous Diablo games.

Players team up with Deckard Cain to defeat echoes of the Prime Evils. A secret cow level quest culminates in a fight against Moophisto, the Divine Bovine, while a secret fishing boss called Mefishto can be caught.

New runewords and classic items have been added, including Enigma. Players can also visit Old Tristram with Diablo 1 NPCs Griswold, Wirt, and Adria by finding all of Deckard Cain's journals. Diablo 3's Whimsyshire is now in the game as well.

The Lucky Coin questline's final coins can be found in Season 15, leading to an Echo of the Horadrim boss fight. That encounter rewards a Horadric Coin whose purpose is unknown. A secret sheep level rewards an item called Map of the Stars, and one piece of the cow-themed Bovine armor set is still missing.

Looking ahead, Diablo 4 will not receive new expansions as focus shifts to Diablo 5, due for release in 2029. The Amazon will be added as a standalone class DLC in the first half of next year. Gamespot reported the season's details.
