That first time you cook up a character, complete with a complex backstory.
That first time you search through a treasure chest to find a magical weapon inside. The next time you start a campaign, you can confidently toss your very own set of dice (hopefully to a critical hit).. The set comes with all of the dice you'll need, including a D20, a D12, a D10, a D8, a D6, and a D4.
