Godey can be found in the kennels of the Szarr Palace where he tortures vampire spawn for Cazador. The kennels are just around the corner at the bottom of the stairs. The door is hidden, disguised as red and gold wallpaper in an arch on the wall. If you fail the perception check you can still access the room by lighting up the brazier to the left. Godey will confront the party if they enter the kennels and has unique dialogue if Astarion is in the party. He will mock Astarion and reminisce on all the times he tortured him. Godey will drop a Szarr Family Ring when defeated, allowing to progress deeper into the palace.
He can be convinced to hand over the ring willingly by passing 2 consecutive skill checks. The required checks are first Deception or Intimidation with DC 15, followed by Persuasion, Deception or Intimidation with DC 20.
Melee: 1.5 m / 5 ft
