In what ways have you used Charms with narrow applications?

Whether you are talking about Dissonant Lies Made True, Shun the Smiling Lady, or something completely different, there are times when a Charm's usefulness can feel rather niche.

And then someone uses Blue Vervain Binding to send a Behemoth after their enemies, or Avoiding the Truth to make someone more inclined to believe you in general after they already disbelieved you once and were proven right, and you realize you might just not be acting creatively enough.

What were those times for you?
