Finding Agatha's Figurine: For those who are having trouble looking for the figurine, it's literally where you started, go into first person and look at the stairs. You'll find it. Hopefully.
Although I don't answer here, I will make a note in this case. The figurine's appearance point is definitely randomized. In other words, after restarting the game, the figurine may appear in a different location.
I ended up finding it in one of the corners but im not seeing anyone talk ab the prostitue having one too, that threw me off alot, nice one on the creators part it tricked me
Yes, Artemis has her own figurine but at this moment it’s impossible to grab it. I think I will make another quest how to obtain exact that figurine within the next few months.
