Unlocking Old Tristram in Diablo 4 Season 15 requires reading all 10 Deckard's Journals, then returning to Deckard Cain at the Imperial Library to access Deckard's Memory. You can complete this exploration objective before preparing the consumables for Echo of Tristram. Treat browsing Diablo 4 Items as optional equipment planning, not a requirement for opening the town.

Old Tristram Access and Boss Entry Are Different Objectives

The journals open access to Old Tristram; Wirt's Lucky Coin opens the subsequent Echo of Tristram encounter. Reaching town doesn't give you unlimited boss attempts, because each fountain activation consumes a coin.

1 Read All 10 Deckard's Journals

Your first objective is completing the journal collection, not gathering boss materials. A nearby journal appears as a small teal marker on your minimap.

Group your search by region to reduce unnecessary travel.

• Kehjistan contains journals at Gea Kul, the Imperial Library and Scouring Sands, while Hawezar has one at Wejinhani.

• Check Windswept Cabin and the woods northwest of Yelesna in the Fractured Peaks, Hidden Overlook in the Dry Steppes, and Marowen, Braestaig and the Fat Goose Inn area in Scosglen.

Use these locations as a regional checklist, and interact with each journal before moving on. Simply passing its map position isn't the stated collection requirement.

2 Return to Cain and Enter Deckard's Memory

Reading the complete collection grants Deckard's Journey, which sends you back to Cain at the Imperial Library. Turning it in opens the portal to Deckard's Memory.

Keep the town unlock distinct from seasonal power progression.

• Entering Deckard's Memory takes you into Old Tristram after the journal quest hand-in.

• Patch 3.2.3, released October 14, 2026, prevents consuming a Prime Evil Splinter before completing the seasonal questline, but doesn't repair previously affected characters.

For an already affected character, complete the seasonal questline on a new character in the same Normal or Hardcore and Normal or Solo Self-Found partition to unlock Prime Evil Powers there.

3 Prepare a Coin Only for the Boss Encounter

Wirt's Lucky Coin matters when you're ready to progress beyond visiting town. The encounter pits you against Diablo, Baal and Mephisto together.

Preserve the ingredients until you've chosen that objective.

• Combine one Splinter of Terror, one Splinter of Destruction and one Splinter of Hatred in the Horadric Cube.

• Use the resulting coin at Old Tristram's fountain to open the red portal into Echo of Tristram.

Budget another coin for another activation; unlocking the town doesn't remove that recurring cost.

What Should You Do Next

Finish the journal collection and Cain's hand-in first, then decide whether you're visiting town or preparing for Echo of Tristram. Any decision to buy Diablo IV Gold should follow your equipment priorities, with spending kept optional.
