Overview
- Blizzard will run a public Season 15 PTR (version 3.2.0) from August 4 to August 11 so players can test the announced changes before final release.
- The Horadric Cube gains an Upgrade Direct recipe that converts a specific Unique into a matching Mythic version while keeping its affixes, and Blizzard says the random elements have been removed.
- Any Mythic made with the Cube will carry a Crafted tag and players may equip only one Crafted Mythic at a time, while other crafting routes from the Jeweler and Blacksmith remain available for non‑crafted Mythics.
- Season 15 introduces Soul Splinters, new socketable items that grant big bonuses with tradeoffs, and returns Rebirth so eternal characters can be converted into seasonal ones and reset to level one.
- Blizzard is also testing experimental overworld systems called Challenge Dungeons and Overland Ambushes, and the studio is holding back further Season 15 details for a staged reveal at BlizzCon.
