The Darkening of Tristram returns January 3, 2023

Kill Unique monsters in the Labyrinth. This one can take a bit to complete but most of these enemies will be found if you go through the Labyrinth a few times. Once you've gone through a few times, skip to the floors with the remaining monsters you need to finish this achievement. Below you'll find the floor that each Unique Monster is located on, two of them are found in the Unholy Altar which lies between the 15th and final floor.

Kill the Dark Lord in a solo game starting with a Level 1 character in The Darkening of Tristram event. For this one you have to go in solo and must enter the portal at Level 1, so don't kill anything as you're making your way there. This is the intended and most fun way to experience this event, but you can instead go in with your level 70 character and smash through it. Keep in mind you can still use your Paragon points at Level 1 if you want to get through it as easily as possible. Find The Dark Lord at the end of the Labyrinth and slay him to get the Butcher Pet and Red Soul Shard. The Red Soul Shard is a Legendary Gem that can only be obtained in this event and gives you another Transmog as well. This is the only Legendary Gem that can be equipped into the players Helm as well.

Collect all the Cultist's Pages from the precursor event. The Cultist Pages drop from Temporal Priests which are new enemies that can be found with ease in Act's I, III and IV. Once you find one in an area move on to the next one as multiple Priest's won't spawn in the same zone, you can also leave game and check the same area again in a new game. Core of Arreat and Gardens of Hope Tier 1 both have the spawn point near the Waypoint, making these great options to quickly check. These Cultist's Pages are actually tradable so you can work with your friends or communities to get everyone what they need. Some areas you can find a Temporal Priest include:

Acquire Wirt's Leg in The Darkening of Tristram event. This one is more time consuming than some of the other objectives but luckily it counts for this achievement and allows you to obtain the Royal Calf pet later on!

1. Obtain the Rotten Mushroom from the Black Mushroom on the ground on the 9th floor of the Labyrinth.
2. Take the Rotten Mushroom to Adria's Hut on the far East side Tristram, click the Cauldron and the Witch's Brew will drop on the ground.
3. Head back through the portal in the Old Ruins and locate the 4 corpses. Farnham's corpse to the South, Ogden's corpse to the North, Pepin's corpse to the West and Griswold's corpse to the East.
4. Click on these corpses in the following: South, North, West and East and take each item that drops to the next corpse. The final corpse will drop a Blacksmith plan for Wirt's Leg that you can learn with Headrig in town to craft the item.
5. Once you have acquired this item go ahead and salvage it (I know all that work and it's gone just like that). You should now have the "Map of the Stars" in your inventory.
6. Take the map East of Adria's Hut where you'll find 3 cow corpses on the ground. Click the cows in the following order: Center, Left, Right and enter the Abandoned Farmstead through the portal that appears.
7. Walk all the way through to the end and in the center you'll find Wirt's Stash which will drop the Royal Calf pet. Yay!
