Mixing Agrippa's Tonic Solution:

  1. Inside the Laboratory, locate the three scientific tools: one on the left, one in the middle, and one on the right.
  2. Go to the device on the right. Open your inventory and use the Glass Jar of Blood on it. Turn the valve. Once heated, grab the jar to obtain the Incomplete Tonic.

  5. Open your inventory again and use the Incomplete Tonic on the square part. Pull the lever.
  6. Grab the Incomplete Tonic afterwards.

  8. Open your inventory and choose the Poison Gland. Use it on the device.
  9. Turn the crank on top of the device until it squishes the Poison Gland.
  10. Congratulations, you have made Agrippa's Weyer's Tonic! Grab it.

Continuing After Mixing Tonic:

  1. Exit the Laboratory and continue forward.
  2. Go through the door and down the stairs to see Agrippa again. He will mention the Laboratory might be accessible.
  3. Wait for him to tell you that you can feed him the tonic and then decapitate him to take his head to fight Alexander.
  4. Open your inventory, select Weyer's Tonic, and use it on Agrippa.
  5. Turn left and move through the new hole to find the Bone Saw.
  6. In the new room, go to the shelf and grab the Bone Saw.
  7. Exit the room through the hole and return to Agrippa.
  8. Use the Bone Saw on him.
  9. Pick up his head from the ground.
  10. Turn right and head straight.
  11. Go through the door, returning to the Chancel where you were ambushed previously.
