So these cards look very useable in 4th edition, but the DC values seem all over the place. Does Pathfinder calculate DC differently? For example, an easy check card has a DC of 10, while a hard challenge has a DC of 25. So this cannot simply be a matter of "Subtract 5 from all DC checks on cards", since a DC5 is abysmally low.
Is there a way to "transate" the DC numbers across to 4th?
