The ongoing Season of Hell's Legacy for Diablo 4, which celebrates the series' 30th anniversary by bringing back familiar bosses and characters, has surprised players with a hidden tribute to Diablo 2. Beyond the inclusion of updated versions of iconic bosses like Diablo, Baal, and Mephisto, and a dream sequence featuring Deckard Cain, players have unearthed secret crafting recipes.

A Diablo 4 streamer named Dioxide was among the first to discover that specific runes and a low-quality chestpiece, when combined in the Horadric Cube, produced the Stealth chestpiece—a Unique item from Diablo 2. This recipe was not officially announced by Blizzard and was only revealed when the player experimented with the game's crafting system. The recovered Stealth armor offers similar relative power to its original counterpart due to its additional stats compared to standard Unique items in Diablo 4.

This discovery has generated significant player interest, leading to speculation about what other secrets and Easter eggs from Diablo 2 might be hidden within the new season. The Season of Hell's Legacy also features a subtle hint towards Diablo 3's Whimsyshire level in its recent trailer, suggesting Blizzard's intention to embed more nostalgic content for players to uncover.

Blizzard has adopted a strategy of leaving hidden content for players to find since the release of the Lord of Hatred expansion. This approach, exemplified by the community's eventual discovery of the secret cow level, contrasts with previous seasons where content felt fully revealed at launch. This method is seen by some as a way to recapture the sense of mystery present in the earlier Diablo games.
