I just need a neutral opinion on this situation: There has been a long-range battle (~150 feet distance) and group A is very likely to win. To get the remaining enemies to give up, group A used intimidation at range very effectively. This caused the survivors from group B to run for it. But group A doesn't want them to run, they want to capture them to get their loot and interogate them. But they can't outrun them (they don't even try). So group A's approach was to throw ranged weapons in front of their feet to get them to stop and let them get captured.
Question: If you were in the feet of group B, would you stop or would you rather feel motivated to run even faster?
(If you say the outcome is unclear, what kind of roll would you do to make the decision?)
If you as DM are uncertain as to how something will turn out, that's precisely when ability checks come into play. You have established Group B as trying to leg it. The PCs don't want that outcome and do something to try and prevent it. The stakes for the ability check are thus pretty clear: (Success) Group B stays put or (Fail) Group B runs or, alternatively, some of Group B runs while others stay put (or even Group B stays put, but it costs extra ammunition to make it happen).
A couple of checks could be appropriate here. Charisma (Intimidation) is the obvious choice. Another good choice might be Dexterity (Intimidation) for placing the arrows or whatever in a spot that would cow the enemy. I don't think Persuasion applies here.
