Hey there, Yavn here. After days of searching I have found the “Conductor Stick”.

Here is the where and how you can find it. It is located in the Wax Museum. The wax museum is inside of the Travelling Academy.

Here is how it looks like in your Wiki.

It is located on Count's jacket zipper.

It’s very hard to click on. It probably will take you a few tries on click on it.
