> Here’s another secret: You don’t actually have to set the DC before the player rolls the check. Decide whether the character succeeds based on the check result. You’ll probably find that your gut feeling (and the player’s) squares pretty well with the set DCs presented here. A number below 10 is never going to make it. A number in the low teens is good enough for an easy task. A number in the middle teens will succeed at a moderate task. And when a player rolls a 16 or better, there’s usually little question that the character succeeds.
