In Diablo 4, players who explore every corner of Sanctuary are rewarded with hidden quests and cryptic lore that tie directly into the series’ most legendary figures. One such secret side quest is “Way of the Three,” a Diablo IV Items hidden mission connected to the Prime Evils—Mephisto, Baal, and Diablo. This quest doesn’t appear in your journal automatically, nor is it handed out by a traditional NPC. Instead, it’s a lore-rich puzzle requiring exploration, interaction with secret items, and overcoming powerful demonic enemies.

This guide covers everything you need to know about how to start the Way of the Three quest, where to find the hidden clues, what the quest entails, and what rewards await brave adventurers who uncover this long-lost demonic path.

Quest Overview: Way of the Three
Quest Type: Hidden Side Quest

Region: Scattered (primarily Kehjistan and Hawezar)

Prerequisite: Discovery of three hidden relics linked to the Prime Evils

Recommended Level: 45+

Objective: Locate and activate three ancient shrines dedicated to Diablo, Mephisto, and Baal

Reward: Rare loot cache, XP, unique cosmetic, and Prime Evil lore entries

How to Start the Way of the Three Quest
This quest does not begin like a typical side mission. Instead, players must find and interact with three hidden relics scattered across Sanctuary. Each relic represents one of the Prime Evils, and finding all three unlocks the true questline.

Step 1: Locate the Prime Evil Relics
1. Diablo’s Sigil

Location: Found deep within a ruined chapel in Kehjistan (near Altar of Ruin).

Clue: Interact with a scorched altar surrounded by ash and charred corpses. A fiery glyph of Diablo appears, and the area shakes.

2. Mephisto’s Tear

Location: Inside a sunken crypt in Hawezar, south of the Vyeresz ruins.

Clue: Look for a corrupted fountain surrounded by cursed spirits. Activating the tear triggers a ghostly whisper and unlocks a journal page detailing Mephisto's schemes.

3. Baal’s Fang

Location: Hidden behind a breakable wall in a dungeon in the Dry Steppes.

Clue: You’ll need to find a crumbling structure in the Forgotten Gulch. Smash the wall to reveal a secret room containing the fang and Baal’s echo.

Once all three relics have been collected, your map will reveal “The Triune Circle”, a secret location at the heart of Kehjistan.

Main Quest Steps
Step 2: Travel to the Triune Circle
This cursed ritual site was used by the Cult of the Three in ancient times. Upon arrival, place the three relics at the altar. This triggers a multi-phase boss gauntlet where you face elite demonic echoes of each Prime Evil.

Step 3: Defeat the Echoes of the Three
Echo of Diablo: Uses fire magic, fear, and teleportation. Dodge high-damage AoEs and use chill/freeze if available.

Echo of Mephisto: Specializes in poison and curses. Bring poison resistance and cleansing skills.

Echo of Baal: Heavy crowd control and clone-based confusion attacks. Stay focused and eliminate illusions quickly.

These are not full-fledged bosses, but they are significantly tougher than typical elites and require solid gear and defensive cooldowns.

Step 4: Purify the Triune Circle
Once the echoes fall, use a crafted Prime Seal (obtained from completing the previous fights) to seal the altar. This grants access to a final chamber filled with lore, gold, and a reward chest that may drop:

Unique gear with demonic-themed modifiers

A cosmetic Prime Evil sigil for your banner

Codex of Power affix upgrade (e.g., Fire damage, Curse effectiveness, or Demonic resistance)

Tips for Completion
Don’t attempt under-leveled: Level 45+ is recommended, especially with strong resistances.

Play in co-op if possible: The triple boss gauntlet is much easier with support or distraction.

Bring status removers: Poison, curse, and fear can disable you for long periods.

Save your cooldowns: Echoes often chain abilities in the final 30% of their health. Be ready.

Why the Way of the Three Matters
This hidden quest is more than a bonus challenge—it’s a nod to longtime Diablo lore fans, referencing the Triune, the ancient cult that worshipped all three Prime Evils as gods. Through haunting journal pages and boss encounters, it teases the possible future return of these forces and deepens the dark mythology that underpins the entire series.

Final Thoughts
The Way of the Three is one of Diablo 4’s most rewarding hidden quests—both in terms of challenge and lore. It emphasizes exploration, curiosity, and understanding the evil that shaped Sanctuary long before Lilith’s rise. If you’re the kind of player who loves uncovering secrets, challenging combat, and unlocking rare loot, seek out the three relics and walk the path of the Triune.

Just beware: following in the footsteps of the Prime Evils may lead to buy Diablo IV Items truths too dark for even the most seasoned Nephalem to bear.
