The page 33 of the PDF reads:

"D10

Roll a d20 when using a scroll, drinking a potion, or casting a spell."

Shouldn't that d20 be a d10?

Also, there is a minor spelling error on the same page:

Roll dice baesd on what action(s) you want to perform on your turn.

You're correct about the d10 and thanks for spotting something we missed in editing!
