Achol:
Harmonious Presence Meditation works as you've described. Committing motes to an indefinite charm is just like committing them to an artifact attunement.
Okay. From which pool are attunement motes dedicated? Several passes through the book are unclear on this.
My sense of the two pools is that "personal" motes are for "being shady and not letting on you're a demigod", while "peripheral" motes are for "look at me, you poor, sad, soon-to-be-dead plot devices".
If Salmon dedicates 7 motes from his peripheral pool for Harmonious Presence Meditation, does that mean he's walking around with an active anima (having spent more than 5), and thus obvious? Does that mean he should use his personal pool (and therefore has less opportunity to use Charms with a degree of subtlety)?
