As a mental defense it’s just as unwieldy to use as Heart-Eclipsing Shroud, which seems meant more as a disguise for your real feelings and identity than as a mental defense.
The Lunar Charm takes just as long to use, so it is just as awkward as a mental defense. And the transformation doesn’t change your Defining Intimacies, so it isn’t as good at disguising what you really think, OR protecting you from social influence.
It lets you play the story of a character with a darker alter ego or second self, and back that story up with mechanics. Some Charms are written for a specific mechanical purpose, but this isn't one of them.
