Hello,
The Premium Fig Edition should include the below based on my pledge manager page:
Digital Copy of Pillars II
Digital Guidebook Volume II
In-Game Pet
Special In-Game Item #1
Special In-Game Item #2
Digital Soundtrack
"Cooking with Tim, Vol. 1" Digital RPG Cookbook
Pillars of Eternity Pen & Paper Starter Guide
Which looks like the Explorer's Pack to me.
