Dragon Age: The Veilguard Lower Labs Walkthrough

First, listen to the information from Tarasal, then pick up the key from the work table and use it to open the door. Destroy all the zombies that you meet along the way and move to the door in front of which Solas and Tarasal are standing. When you enter the room with the statue, start rotating it to open all the doors in sequence and destroy the red nodes of corruption that you come across. One of these nodes is located in the central room with the statue.

After you manage to unlock the passage, go deeper into the laboratory. Choose a moment to go outside and fight the monsters located there. Continue your way, destroying several enemy groups, and eventually receive the first Wolf statuette as a reward for your efforts.
