TL;DR — How do you unlock Uber Tristram in Diablo 4 Season 15? Collect all 10 Deckard's Journals across Sanctuary → enter Old Tristram via Deckard's Memory portal → defeat the Pinnacle Waking Nightmare bosses in Durance of Hate (Mephisto), Worldstone Keep (Baal), and The Labyrinth (Diablo) at Torment X to earn three Splinters → transmute them in the Horadric Cube into a Wirt's Lucky Coin → use the coin at the Tristram fountain to open the red portal to Echo of Tristram. Defeating all three Uber Prime Evils drops the Hellfire Torch Mythic Charm (+1–4 All Skills, +10–20% All Stats, +10–20% All Resist, extra Unique Charm slot). Minimum difficulty: Torment 6 to enter. Official Season 15 patch notes.
Season of Hell's Legacy hides one of Diablo 4's deepest endgame secrets: a full Uber Tristram chain lifted straight from Diablo 2 lore. You walk through an old town, collect a lucky coin, and challenge all three Prime Evils at once for a charm that's now considered the best-in-slot Mythic for most builds in Season 15.
Getting there takes more steps than any other endgame encounter. This guide covers every step — from the first journal to the Hellfire Torch — with exact locations, farming shortcuts, and fight tips verified against official sources as of October 6, 2026 (patch 3.2.2).

What is Echo of Tristram in Diablo 4 Season 15?
Echo of Tristram is Season 15's secret pinnacle boss encounter, a direct nod to the Uber Tristram event from Diablo II: Lord of Destruction. Instead of pulling the three Prime Evils apart to fight them one by one (as in D2), Diablo 4's version drops all three — Echo of Baal, Echo of Mephisto, and Echo of Diablo — into a single arena.
The encounter is gated behind a multi-step quest chain. The reward is the Hellfire Torch, a Mythic Unique Charm that returns from D2 with updated stats for Diablo 4's talisman system.
What does the Hellfire Torch do?
The Hellfire Torch is an Ancestral Mythic Unique Charm with the following confirmed stats for Season 15:
| Stat | Range |
|---|---|
| All Stats | +10–20% |
| Resistance to All Elements | +10–20% |
| All Skills | +1 to +4 |
| Special | Equip one additional Unique Charm in your talisman |
| Set Bonus | Counts as a piece of your class's Nameless Set |
The extra Unique Charm slot is the headline effect. Combined with the Annihilus Seal (which reduces your set item requirement by one), you can simultaneously wear a 5-piece set bonus and two extra Unique Charm powers — an interaction Blizzard confirmed it will not patch during Season 15, per their September 30, 2026 forums post.
How Do You Start the Uber Tristram Chain?
The chain begins with Deckard Cain and a hidden journal hunt. After completing the opening Tarsarak tavern intro for Season 15, 10 satchels appear across Sanctuary. Reading all 10 triggers the "Deckard's Journey" quest.
All 10 Deckard's Journal Locations
Each journal appears as a small teal dot on your minimap when you are nearby. The locations below use the closest waypoint as a reference:
| # | Zone | Region | How to Find |
|---|---|---|---|
| 1 | Gea Kul | Kehjistan | Southwest of the waypoint, on the wooden dock (~60m) |
| 2 | Imperial Library | Kehjistan | South of the Blacksmith anvil, near the main doorway |
| 3 | Scouring Sands | Kehjistan | Northeast from Tarsarak waypoint, east of the Vault of the Crucible entrance |
| 4 | Wejinhani | Hawezar | East of the waypoint, left of the Alchemist |
| 5 | Lorath's Cabin (Windswept) | Fractured Peaks | Between Kyovashad and Nevesk; enter the cabin and check the bedroom |
| 6 | Hidden Overlook | Dry Steppes | West of waypoint, at the broken bridge near the lookout |
| 7 | Marowen | Scosglen | West-side dock in town |
| 8 | Braestaig | Scosglen | East of the waypoint, near the Penitent Cairns dungeon entrance |
| 9 | Fat Goose Inn | Scosglen | Near the Oldstones dungeon entrance, inside the Fiefdom House |
| 10 | Yelesna | Fractured Peaks | Northwest into Mistral Woods, in a small clearing |
Entering Tristram
After reading all 10 journals, return to Deckard Cain at the Imperial Library. Turn in "Deckard's Journey" and he opens a portal to Deckard's Memory — step through to arrive in Old Tristram, the town from Diablo 1.
You will find familiar faces: Ogden (gives the "Ogden's Sign" side quest — see our Ogden's Sign guide for a free Harlequin Crest), the Wounded Townsman, Adria, Wirt, Pepin, Griswold, and Deckard himself.
Wirt matters here — his Lucky Coin is the item that opens the Echo of Tristram portal.
How Do You Farm the Three Prime Evil Splinters?
To craft Wirt's Lucky Coin you need all three Prime Evil Splinters:
- Splinter of Hatred — from defeating Mephisto in the Durance of Hate (Pinnacle) Waking Nightmare
- Splinter of Destruction — from defeating Baal in the Worldstone Keep (Pinnacle) Waking Nightmare
- Splinter of Terror — from defeating Diablo in The Labyrinth (Pinnacle) Waking Nightmare
Where Are the Splinter Dungeons?
These are the Pinnacle Capstone versions of the Season 15 Waking Nightmare dungeons, available at Torment X (T10+). They appear on the map as red seasonal dungeons with a green leaf icon. For a full overview of all Waking Nightmares, see our Waking Nightmares Season 15 guide.
| Dungeon | Region | Boss | Splinter |
|---|---|---|---|
| Durance of Hate (Pinnacle) | Hawezar | Echo of Mephisto | Splinter of Hatred |
| Worldstone Keep (Pinnacle) | Fractured Peaks | Echo of Baal | Splinter of Destruction |
| The Labyrinth (Pinnacle) | Scosglen | Echo of Diablo | Splinter of Terror |
Each dungeon drops its splinter on boss kill. For detailed strategies on the Worldstone Keep and Baal specifically, see our Worldstone Keep Season 15 guide.
"Hotfix 4 … Fixed an issue where the Tristram fountain would consume Wirt's Lucky Coins but fail to open a portal." — Blizzard Entertainment, September 22, 2026 Hotfix 4 notes
This Hotfix 4 fix is the reason the Lucky Coin mechanic now works reliably in patch 3.2.2. If you farmed Splinters before September 22, your experience was likely broken — the portal simply would not open.
How Do You Craft Wirt's Lucky Coin?
With all three Splinters in your inventory:
- Open the Horadric Cube (found in Temis or carried in your inventory)
- Place Splinter of Terror + Splinter of Destruction + Splinter of Hatred in the transmutation slots
- Transmute → receive Wirt's Lucky Coin
Each Lucky Coin is consumed on use. Every Uber Tristram run requires farming a fresh set of Splinters from all three Hell-tier dungeons.

How Do You Enter Echo of Tristram?
Return to Old Tristram with the Lucky Coin in your inventory:
- Find the Fountain in the center of Tristram — it becomes interactable only when you are carrying the coin
- Click the Fountain → it glows red and opens a portal labeled "??????"
- Step through → revealed as Echo of Tristram
Minimum difficulty: Torment 6. Attempting to enter below T6 gives the message "The minions of Hell are too strong." Most players farm efficiently at T8–T10+.
How Do You Beat the Echo of Tristram?
Unlike Diablo 2 where you could separate the bosses across different levels, Diablo 4's version forces a simultaneous three-boss fight. All three Echoes — Baal, Mephisto, and Diablo — are present at once.
Fight Strategy
- Do not stack overlapping attacks. Each boss has a distinctive pattern (Mephisto: poison clouds + lightning nova; Baal: teleport + summoning; Diablo: fire floor + charge). Getting caught in two at once is lethal below T10.
- Maintain mobility. There is no safe corner — the arena is a flat area and boss abilities spread across it. Builds with a dash or teleport survive far more comfortably.
- Stack all resistances before entering. You will face Fire (Diablo), Cold/Lightning (Mephisto), and all-element (Baal) damage simultaneously. A Splinter of Pain (Poison DR) and high baseline resistances reduce the spike damage noticeably.
- You can portal to town mid-fight to repair equipment if needed — the encounter persists.
- Target priority: No strict priority; focus whichever boss has the most dangerous attack pattern active. Mephisto's poison cloud can zone out large areas; clearing that attack first makes the arena safer.
Rewards
Each Echo of Tristram run drops:
- Hellfire Torch (Mythic Unique Charm, guaranteed per run)
- Standard of Heroes (Unique Trophy, quest item — purpose not yet confirmed by Blizzard; hold onto it)
- Mythic Items and Mythic Charms from the general loot pool
How Do You Farm Uber Tristram Efficiently?
Because each run requires three fresh Splinters from three separate dungeons, the farming loop is:
- Run Durance of Hate (Hell) → Splinter of Hatred
- Run Worldstone Keep (Hell) → Splinter of Destruction
- Run The Labyrinth (Hell) → Splinter of Terror
- Transmute in Horadric Cube → Lucky Coin
- Echo of Tristram run → Hellfire Torch
At T10, expect roughly 15–25 minutes per full loop depending on build speed. Party members do not need their own coin — one coin per group per run is shared.
For players at T8 and below, the three Hell-tier dungeon bosses (especially Diablo's Labyrinth version) are the bottleneck. Running with a party or using a Diablo 4 boss carry service cuts the Splinter farming time significantly.

FAQ
Is the Hellfire Torch account-bound in Season 15? Yes, the Hellfire Torch is bound to account on pick-up. It is not tradeable.
Can you get the Hellfire Torch multiple times? Yes. Each Echo of Tristram run guarantees one Hellfire Torch drop, so you can farm for better stat rolls (higher All Skills, higher All Stats/Resist percentage). You need a new Lucky Coin per run.
Do you need to complete the seasonal questline before farming Echo of Tristram? You need to complete the Deckard's Journal chain (10 journals → Tristram access) and unlock Torment X for the Hell-tier Splinter dungeons. The broader seasonal story does not block the Uber Tristram chain.
What is the minimum Torment for Echo of Tristram? Torment 6. The fountain portal will not open below T6. You receive full rewards at any difficulty above T6, with Torment 10+ preferred for efficient runs.
Does the Annihilus stack with the Hellfire Torch? Yes. The Annihilus Seal and the Hellfire Torch occupy different item slots (Seal vs Charm) and stack normally. The Hellfire Torch's extra Unique Charm slot then lets you equip a second Unique Charm alongside your set, enabling the 5-piece bonus + two Unique Charm powers interaction confirmed live through September 30, 2026.
