Diablo 3: Darkening of Tristram Guide


~ 18 min read
Translate this page to...

From its’ development in late 2016, Blizzard has paid homage to the Diablo series’ origins, re-creating the first Diablo game within a free, annual event for Diablo 3. Ever since its’ launch in January 2017, Diablo 3’s Darkening of Tristram Event has reoccurred since.

Now that the game has released on the Switch, I’m obligated to create the most definitive guide on the event, including everything from the event’s challenges, down to the collectible lore books/journal entries within.

According to the game’s website, the precursor event starts on December 31st at 4PM PST, and the portal leading to the main event starts on January 3rd at the same time. Both portions of the event are set to end on January 31st, also at 4PM PST.

Returning players, if you have previously completed the event from prior years, there are no new rewards to unlock. Feel free to read on, if you wish!

Event Overview

As part of the Diablo series’ anniversary, every January, owners of the Reaper of Souls expansion or the Eternal Collection can revisit Tristram many years in the past, across all consoles, before it fell to ruin.

The event is played entirely in Adventure Mode, and consists of two parts: the precursor event, which provides backstory, and the main anniversary event, taking place in The Old Ruins of Act I.

Once the main event is ready, players can travel to Act I and check the map for a red pentagram. Afterwards, a retro adventure awaits in The Ruins of Tristram!


Throughout the event, there are a few limited-time rewards to claim, available only until the event closes. Most of the rewards are account-bound, and usable across all character states. (Seasonal, hardcore, etc…)

From the event, players can claim 2 pets, 2 portrait frames, three equipment transmogs, a Banner Accent, Banner Sigil, and an exclusive legendary gem, for a total of 10 rewards, and 140 challenge points.


Butcher – Getting the butcher pet is fairly straightforward, and is unlocked upon the completion of the “An Eerie Red Glow Blurs Your Vision” challenge.

To get this pet, take a level one character through the Labrinth, and complete the 16th level. The only catch here is that this must be done in a solo game, without other players present.

Upon defeating the Dark Lord, the pet should be unlocked.

Royal Calf
– Originally a secret pet, the Royal Calf is arguably the hardest of the two event pets to find, and isn’t the most intuitive to discover, being locked behind a small fetch quest. The entire process can be done in 13 quick steps, however.

  1. First, travel to Tristam, through the event portal in the Old Tristam Ruins, and traverse the Cathedral’s Labyrinth until reaching Level 9 of the dungeon.
  2. Then, once players reach Level 9 of the Labyrinth, they will have to search the entire area to find the Black Mushrooms, and interact with them.

    These do not stay in a fixed location, so players will have to actively search for them.

  3. Once touched, the Black Mushrooms will drop a Rotten Mushroom. Take the Rotten Mushroom back to Adria’s hut, and put it in the Cauldron. You’ll receive a Witch’s Brew in return.
  4. Remember the dead bodies of Tristram’s slain townsfolk? It’s time to help the deceased find peace.

    Walk back to the main entrance of Tristram, and interact with Farnham’s Corspe behind the bottom right house.

    Craving a strong drink, the Witch’s Brew gives Farmham peace, and his ghost gives you the Drunkard’s Debt in kind.

  5. Having the Drunkard’s Debt in hand, walk to the topmost house, and give Farmham’s debt to Ogden.

    Ogden collects what he is owed, and gives you Garda’s Letter, to pass onto the town’s cleric.

  6. With your hero now officially a courier for the dead, walk down just a few steps to Pepin’s Corpse, whose spirit yearns to help the afflicted.

    Upon receipt of Garda’s Letter, he leaves a Healer’s Prescription, for delivery to the town’s blacksmith.

  7. Finally, a few more steps to the northeast lies Griswold’s Corpse. Giving him the Healer’s Prescription allows to him create the plans for Wirt’s Leg, which your hero can then learn, for your blacksmith to later produce.

    You’re almost done at this point!

  8. Now that the plans for Wirt’s Leg have been acquired, learn them, if you haven’t already, and speak to your blacksmith, Headrig, about the leg.
  9. For 10 Reusable Parts and a whopping million gold, Headrig can create the leg as a usable weapon.

    From the weapons tab, go to the right slot of the weapon wheel, and go down to the bottom of the list of maces. Craft Wirt’s Leg.

  10. With Headrig now a rich man, inspecting your new weapon reveals that it’s, well, … junk at best.

    Take Wirt’s Leg, and salvage it back for parts. At the very least, you get a weapon transmog for your trouble.

  11. Instead of crafting materials, salvaging Wirt’s Leg yields a special item, the Map of the Stars. Head back to Tristam, and to the Dead Cows near Adria’s hut.

    If the cows have already been clicked on or touched, restart the game, continuing to the next step.

  12. With the Map of the Stars in your character’s inventory, interact with the cows starting with the middle, then the left cow, and lastly the right cow.

    When done correctly, the cows will moo musically, and the entrance to the Abandoned Farmstead will be revealed.

  13. Finally, go to the middle of the farmstead, where Wirt’s Stash is tucked away.

    Opening it will drop a small amount of gold and the Royal Calf pet, resulting in dire circumstances to the storyline. You now have a gold-seeking calf as a pet!

Equipment Transmogs

Butcher’s Cleaver (1H Weapon) – The Butcher’s Cleaver is earned by killing the Butcher in the Labyrinth’s 2nd Level.

Despite its stringy blood and basic shape on the weapon’s item card, the equipped version has a deep blood stain and a more realistic appearance.

Wirt’s Leg (Mace) – No, it’s not as grotesque as it sounds. Wirt’s Leg is simply a wooden peg leg, held at the narrow end of the leg, and bashing enemies at the broader end.

This leg is a craftable only weapon, and the plans required for it are locked behind a somewhat obscure quest line involving a Rotten Mushroom found in the Labyrinth.

Red Soulstone (Head) – the last item transmog is the Red Soulstone, and is received when socketing the Red Soul Shard legendary gem into a head equipment slot.

As a transmog, the Red Soul Shard can be equipped on any character class to make them a Dark Wanderer of their own right, complete with hazy eyes and a large, protruding rock in their head.

Banner Customizations

Killing all of the event bosses in the Labyrinth will award players with both Ogden’s Sign, (a banner sigil) and Ogden’s Brew, (a banner accent.)

Visually, Ogden’s Sign appears similar to a stylized sun, and adds bar mugs to the banner’s top corners when the sigil accent is toggled.

Ogden’s Brew, on the other hand, depicts various bottles, with crossed keys in the middle.

Legendary Gem

Completing the anniversary event and slaying the Dark Lord will net players the Red Soul Shard legendary gem, equippable only when socketed into head armor.

As for its ability, it is offense-based, but puts the player at risk. It causes a ring of fire to appear around the player, dealing 12,500% weapon damage to every enemy it hits, however, this occurs only when the player’s hero is periodically struggling for control of their body, resisting Diablo.

At level 25, the gem removes the resource costs of skills for 30 seconds after leveling up, and skill cooldowns are reduced by 75% for the same 30 seconds. Successfully raising the gem’s level boosts the damage it does by 50% per gem level gained.

The gem, like all other legendary gems, is farmable, but only when no copies of it exist in the players inventory, as well as there not being any in the stash. Dropping all copies of the gem on the ground before clearing the Labyrinth will also result in the gem dropping as loot.


Thank Goodness You’ve Returned! – Kill all 4 bosses in the Darkening of Tristram event. (20pts.) Rewards: Sigil and Accent for banners.

Note: This is a fairly straightforward challenge. Skip to the Event Bosses section for details about where to find each boss.

Adventuring Hero – Kill one unique monster from the Labyrinth. (10 pts.)

Note: This challenge is part 1 of the Protector of Tristram challenge, and can be completed as soon as reaching the Labyrinth’s 2nd level. Skip to the unique monsters section to see where all of the uniques are located.

Champion of the Townsfolk – Kill 20 unique monsters from the Labyrinth. (10 pts.)

Note: This challenge is the 2nd part of the Protector of Tristram challenge, and may require multiple playthroughs to unlock. Skip to the unique monsters section for a chart of all of the unique monsters.

Protector of Tristram – Kill all unique monsters from the Labyrinth. (10 pts.) Reward: Portrait Frame – Classic Demon.

Note: This challenge is by far the most tedious of the event challenges, and will require multiple event playthroughs. Skip to the unique monster locations section for a table showing where each unique in the Labyrinth is.

I Sense a Soul in Search of Answers – Collect all the Cultist Pages from the precursor event. (10pts.) Reward: Portrait Frame – Classic Angel (Portrait)

Note: This challenge does not require players to have all of the pages collected at once, but instead keeps track of what pages have been found. Skip to the Precursor Event section, or simply have another player drop the pages for you to pick up.

Psst… Over Here… – Aquire Wirt’s Leg in The Darkening of Tristram event. (10 pts.)

Note: Getting Wirt’s Leg involves a small amount of fetch-questing, which is described in the quest items section.

The Dark Passage – Visit the Dark Passage. (10 pts.)

Note: See the optional locations section for more details.

The Chamber of Bone – Visit the Chamber of Bone. (10 pts.)

Note: See the optional locations section for more details.

The Halls of the Blind – Visit the Halls of the Blind. (10 pts.)

Note: See the optional locations section for more details.

An Eerie Red Glow Blurs Your Vision – Kill the Dark Lord in a solo game starting with a level 1 character in The Darkening of Tristram event. (40 pts.) Reward: Pet – Butcher.

Note: This challenge is not the hardest to do, but there are a few myths regarding unlocking it. The most important things to keep in mind is that the character has to start at level 1, and this MUST be done in a single player game.

Precursor Event: Temporal Priests and the Cultist’s Pages

Following the aftermath of the main events of the story’s campaign, a cultist is determined to recover Adria’s possessions and delve into their past, using their knowledge to further progress the cult’s ambitions.

Due to this, Temporal Cultists will scour the lands of Sanctuary, looking for the answers they seek, and preparing a special ritual in the ruins of Old Tristram.

Starting on December 31st, (The first Diablo game’s release date,) these cultists — donned in grayscale colors, can be found in Adventure Mode in certain areas. Finding and killing the Temporal Priests will drop one of the 7 Cultist’s Pages detailing the event’s backstory. Collecting all seven will award the Classic Angel portrait frame.

Confirmed Locations

Luckily, the event cultists can be found in the main areas of the game, easily accessible from each act’s waypoints.

The following locations have been personally verified to spawn a group of temporal cultists.

Act I

Darkening of Tristram Act I Adventure Mode MapDarkening of Tristram Act I Adventure Mode Map.

Fittingly, Act I has ten places in which the temporal cultists and their pages can be found.


  • The Cathedral, Level 1
  • The Cathedral, Level 2
  • The Cathedral, Level 4
  • The Festering Woods
  • The Weeping Hollow
  • The Fields of Misery
  • The Halls of Agony, Level 1
  • The Halls of Agony, Level 2
  • The Halls of Agony, Level 3
  • The Caverns of Araneae

Recommended Locations: In Act I, the best location to search for temporal cultists is the Festering Woods, due to its smaller size and circular area. The Cathedral and Halls of Agony are also great places to search, as they are fairly linear and straightforward.

The Weeping Hollow and Fields of Misery aren’t entirely recommendable, as they are long, open expanses, and the Caverns of Araneae are not recommended, due to dead-ends and possible backtracking.

Act II

Act II only has two places housing temporal cultists.


  • The Dahlgur Oasis
  • The Desolate Sands

Recommended Location: Of these locations, neither is recommended for farming pages, as the locations are large and open, and can take several minutes to locate the temporal cultists. The Dahlgur Oasis is somewhat more tolerable to search, however.


Darkening of Tristram Act III Adventure Mode Map.
©2013 Blizzard Entertainment, Inc. All rights reserved.

Similarly to the first act, Act III has ten locations in which the Temporal Cultists gather.


  • The Keep Depths, Level 1
  • The Keep Depths, Level 2
  • The Keep Depths, Level 3
  • Stonefort
  • Rakkis Crossing
  • Arreat Crater, Level 1
  • Arreat Crater, Level 2
  • The Core of Arreat
  • Tower of the Damned, Level 1
  • The Ruins of Sescheron

Recommended Locations: For all of the long, sprawling dungeons in Act III, there are some locations that are quicker and simpler to search. The best of these are the Core of Arreat, and The Tower of the Damned, as they are smaller areas that can searched within minutes. Coming in as a close second are both of the Arreat Crater levels.

Rakkis Crossing is an iffy recommendation, as the cultists there can appear at the start of the bridge, or be found all the way near the Siegebreaker Assault Beast.

Act IV

The fourth act has five locations in which the Cultist’s Pages can be found.


  • Gardens of Hope, 1st Tier
  • The Silver Spire, Level 1
  • The Silver Spire, Level 2
  • Gardens of Hope, 2nd Tier
  • Gardens of Hope, 3rd Tier

Recommended Locations: In Act IV, The quickest zone to search is The Silver Spire: Level 2, otherwise, The Gardens of Hope’s 1st Tier is a relatively straightforward zone to search, and its 2nd Tier is also fairly decent to search as well, but both may require some backtracking.

Act V

The final act in Diablo 3 has five locations for temporal cultists as well.


  • Westmarch Commons
  • Westmarch Heights
  • Paths of the Drowned
  • Battlefields of Eternity
  • Greyhollow Island

Recommended Location: Picking a recommendation for Act V is no easy task, as all of the locations here are lengthy, and can involve some back-tracking. If one had to be made, it would be the Westmarch Commons, as it is fairly linear.

Anniversary Event: The Darkening of Tristram

The Nephalem in Tristram

Starting January 3rd, a portal can be found in The Old Ruins of Act I. Entering it will take the player to the main part of the anniversary event, in which 16 Levels of the Cathedral’s Labyrinth, as well various monsters, bosses, and secrets, await.

Adding to the nostalgia and charm, The game will apply a grainy, nostalgia filter throughout the event, (dubbed retro vision,) players will move in 8-directional fashion, the original game’s music will play, and text font will be changed while in Tristram. Legendary equipment discovery sounds are also different, as are the interface sounds when pausing the game.

Completing this portion of the event can reward players with pets, a legendary gem, banner customizations, transmogs, and a portait frame.

  1. still do not have a portal on playstation 3 Do I need to collect the pages first or something because it is the 16 Only little less then half the time left remaining to get the anniversary event completed

    • Hi, thanks for stopping by and leaving a comment!

      The only reason you wouldn’t be able to play the event to my knowledge, would be if you aren’t playing it through Adventure Mode, or don’t have the Reaper of Souls expansion pack.

      You mentioned playing the game on the Playstation 3. Do you know which version of the game you have? There’s the base version, simply titled “Diablo 3”, and also an upgraded version of the game, called “Diablo 3: Reaper of Souls – Ultimate Edition.”

      If you have the Reaper of Souls version or expansion pack, then you would have to be playing in Adventure Mode and go to “The Old Ruins” area of Act I. If you don’t have Adventure Mode unlocked, then you’d have to clear the game’s 5th Act, in which you would then unlock it. (Having a friend carry you through the final Quest in Act V also works if you’re in a pinch!)

      The precursor portion of the event, where you can collect the cultist pages, is entirely optional, and does not affect the portal.

      Double-check to see if you have the Reaper of Souls expansion pack, completed the 5th Act of the main campaign, and that you’re playing on Adventure Mode.

      If all of those conditions are met, then you should see a small red pentagram on the Act Map for The Old Ruins in Act 1, and see the portal in the center of the area by the fountain.

      Hopefully this clarifies things for you!
