Setting Obstacle DCs

When you set the DCs for an obstacle, you'll typically be using simple DCs. Use a proficiency rank that's generally appropriate for the PCs' level if you want the obstacle to be a significant obstacle. As noted earlier, you'll typically want to select a couple different ways the group can get past an obstacle. At least one check should have an easy or very easy adjustment, while the other check should have a standard or hard DC. In some cases, you might use something other than a simple DC; for example, if a specific NPC has put up a wall of steel, you would use their spell DC. This might result in some pretty tough DCs or even impassable obstacles, so use this carefully! If a PC improvises a different way to get around an obstacle from what you planned, set the DC just like you would normally when picking a DC on the fly. Don't worry about adjusting the DC to be easy or very easy because the PC is likely to be good at the skill they've chosen.
