A Slow Poison Walkthrough
For this quest, you must speak with Teia and Viago in The Cantori Diamond in the Treviso Canals. From The Cantori Diamond Beacon, you’ll want to head across the rafter then follow the walkway right to find the pair near a table.
After speaking with them, you’ll need to find the Drowned District. Take the stairs down by the merchant then use the zipline to reach the Crow’s Road Rooftops. Head south and travel through the Grande Markets to the southwestern part of the area where you’ll find The Drowned District.
In The Drowned District, head to the southwestern part of this area to find a Crow scout with some enemies. Take the enemies out then interact with Jacobus, Dareth’s cousin, in the cage to free him.
After speaking with the cousin, head over to Dareth’s body on the rug to grab the Bloodstained Note. Return to the beacon where you’ll spot a crow mark. Climb up the ladder and head through the opening.
Pass through the town square to the northeastern side where you’ll go down some stairs. At the bottom, take a left and you’ll spot the crow mark on a board straight ahead.
Head through the entrance to the left of this mark to reach the Grande Markets.
In the market, head east, passing the beacon, to reach the Heart and Central. Head north over the bridge then keep heading straight until you reach the beacon. Climb up the trellis to the left of this beacon to find the next crow mark. Use the ladder and enter the window to reach a crow hideout. Examine the contract on the desk in the corner.
Now that you have the contract, head to the northwestern corner of the room and jump out the window. Head along the roof to find a zipline then zip across.
From there, take another zipline that will take you back to the Crow’s Road Rooftops just outside the casino. Take the next zipline heading north towards the garrison. Pass the beacon then jump across a small gap. Enter through the door then wipe out the enemies inside.
Once defeated, use the nearby zipline. Destroy the enemies along the way to the quest objective inside Antaam Garrison. At the end of the path, you’ll find a closed door. Head through this door and go down the stairs to reach a beacon.
When you’re ready to begin the battle, jump down over the balcony to battle the Level 14 Qamekmaster. After defeating this creature, destroy the three jars of poison and loot the note on the desk. Use the key you received from defeating the boss to open the locked door in the room for a chest.
Next, speak with Teia and Viago in The Cantori Diamond. After the cutscene, the quest will complete!
