What you need to do?
You can earn this stamp in Chapter 12’s Werewolf: Bernard Drinks Poison.
You’ll need to make Bernard howl at the moon in wolf form to receive this stamp.
The solution to earning this stamp is quite clever, where you need to play closer attention to the detail of the scenes you use.
Bernard is only in his wolf form during a full moon. Anything different and he’ll transform back.
Couple that with the fact that Bernard won’t howl at the moon in the scene he transforms results in a requirement for some lateral thinking.
How to get the Phases stamp in Storyteller
Panel 1
Place the first Moon scene, and have Bernard transform into his wolf form.
Panel 2
Use a second Moon scene. Here you should notice that the moon isn’t full. By not placing Bernard here, he won’t transform back and will stay in his werewolf form.
Panel 3
Use a final Moon scene. It will be a full moon again, so you can place Bernard who will start to howl.
