I'm looking at creating a class with a "Grit" like ability, which provides a small pool of points that would allow the class to use other abilities, and would be rechargeable through certain actions.
The class would be a support class, like the Bard, whose chief role is to provide buffs and a diplomatic "face" for the party, with a secondary role as martial backup. Basically, a Marshall or Leader sort of class.
I was trying to think of some non-combat mechanics that could be used as a recharge for the pool; ie, since it's not a front-line fighter, klling an opponent wouldn't be my first choice for recharge.
Offhand, I'm thinking something like perhaps demoralizing an enemy as a recharge mechanic, natural 20 on a Diplomacy check, etc. Something along those lines, but I know that skills are a different sort of beast than To Hit mechanics, so it might not scale quite as well.
Any suggestions? Not necessarily full fledged examples, but even just ideas for the sorts of things that might assist a leader in recharging this ability would be a great starting point.
