Add your weapon’s enhancement & proficiency bonus to any old skill check you feel like.

Enrage Mob
Daily
CHA vs. Number of People in Crowd
Target group of sentient beings is consumed by anger toward any one specific person, group or object (ie, “Count Vorlan,” or, “The Knights of Aglafor”). Anyone with a class in the group can make a saving throw to avoid the effect even if it hits. The mob will delay and harass the target, but won’t overtly attack it or do any damage.

Shrewd Haggling
Daily
CHA vs. Will
Success: Target grants a 20 percent discount on any single purchase made within the next five minutes.

Flattery
Encounter
CHA vs. Will
Trigger: Ally makes a lore check based on streetwise, diplomacy, bluff or insight. The result of the check is one difficulty level higher than what is actually rolled, ie if you get an 18 on the check, you get the lore info block for a 20.

I bow to your superior title-making skills.

Mighty Flex
There’s nothing you can’t do with muscles, from flexing them to impress the other side in a meeting of diplomats, to lifting fallen trees with looking for clues. In any skill challenge, you may always make a Strength check at +4 for a single skill challenge check.

I think we should start with skill challenges. When run properly, a skill challenge is an awesome non-combat encounter. You’ve got to think on your feet and interact with NPCs – last week, our party ran this elaborate ruse on a group of duergar slavers, and the skill challenge was epic. So perhaps charms, illusions, inta-information gathering, things that boost intimidation, things that like that give bonuses to skill challenge rolls. You could introduce dex, str and con based ones for skill challenges revolving around chases or escapes.

I really like the idea of a Utility power called “Bend Bars, Lift Gates,” both because it could be nice for extra oomph when playing the brawny figher and because it’s a nice nod to older editions.

As for Word of Mouth, that’s a great idea too. There’s a feat a lot like that in Mutants & Masterminds (Well-Informed), that (as I recall) lets you make an immediate gather Information check when you first meet someone. Actually, M&M feats might be a great resource for people looking for non-combat powers (or even some new combat abilities — Master Plan would make a great Leadership-role power).

Rogues are a bit trickier– maybe things that let you back date actions? Utility power: You already picked that guy’s pocket. Use it & declare you picked his pocket when no one was looking. Maybe Utility: Word of Mouth– make a Gather Info check without leaving the room; you’ve heard rumors of that in your carousing.

Fighting men are trickier still, but things like “1000 yard stare” immediately come to mind, as do maybe First Aid or maybe feats of Strength or Dexterity? Long jump, bend bars, lift gates…

So what sorts of non-combat powers would we suggest? I’ll let you guys have at it for awhile, and I’ll be back later with my ideas.
