I've been playing a character in Pathfinder recently who is a divine spellcaster but does very little damage in combat, so I've been using a lot of debilitating spells (most notably Terrible Remorse) to stop enemies instead of fighting them head on, and letting party members deal with them.
The only issue is that neither my DM or I know the actual mechanics for determining Difficulty Classes, so we wind up doing a different thing each time. Is anyone familiar with the actual way it works?
