Blizzard sends Diablo 4 players a Resplendent Spark to apologise for Season 15 launch problems

Blizzard has been handing out Resplendent Sparks — one of Diablo 4's rarest crafting materials — as an apology for the rocky launch of Season 15, the Season of Hell's Legacy. The gift arrived via the Horadric Post, an in-game mailing system that was itself introduced with the new season.

The accompanying note read: "We're sorry for any unexpected issues you may have experienced. Thank you for standing with us. Please accept this token of appreciation for our journey ahead." Season 15 launched over two weeks ago but hit multi-hour delays on day one due to log-in errors and server problems. Launch issues also extended to gameplay, including The Tree of Whispers failing to display rewards — all of which have since been fixed through patches and hotfixes.

Resplendent Sparks are among the most sought-after items in Diablo 4. Players normally grind hours of challenging endgame content to earn a single one, and they're used exclusively to craft Mythic Unique weapons and gear — the strongest items in the game. Getting one handed to you for free is a meaningful gesture, not a token trinket.

Not everyone received the Spark, though. Players on Reddit theorise that only those directly affected by the launch issues — such as being unable to claim a Resplendent Spark from the seasonal progression track — actually got the item, even if the apology message arrived for a broader group. Blizzard hasn't officially clarified the criteria, and some players who got the note but not the Spark may simply have hit another server hiccup.
