But isn't that what you did to your players? The dc's were so high that th y needed to go do a completely unrelated quest to level up to the point where they could succeed. I'm not sure I'm seeing a difference.
DCs are never, ever the only way to engage with a problem. In the specific case in question (succubus-inspired murder/suicide), other approaches that might have been fruitful include:
* Speak with Dead (requires cleric or bard 5)
* Detect Evil habitually during social interactions (paladin 1 required)
* Detect Thoughts (requires bard/sorc/wizard 3) on all witnesses
* Zone of Truth -- even if she makes her save she tips her hand (requires bard/cleric/paladin 3)
* All the weird and crazy ideas that my players think up during play, which I never anticipate when writing lists like this. (E.g. Disguise Self as the ghost of murdered man and everybody, "Why did you kill me?!?" in hopes that the guilty party will give themselves away.)
Even when it comes to DCs, due to bounded accuracy, levelling up doesn't even help that much. The following would be more helpful:
* Enhance Ability (Wisdom) during socializing for Wisdom/Insight checks (bard/sorc/cleric/druid 3 required)
* Help: Insight while interviewing (requires multiple Insight-proficient characters in party, if you rule Help that way; or else just requires PCs to think about it if you don't require proficiency to help)
