Two things, first, if we're talking about the same one from the Scion thread:
First, unless I missed something, her Tea Set Focus Item is set up for channeling/evocation (bonuses to Defensive Control and Power), which it appears she doesn't have. If it's meant to apply to her Ritual power, then you need only specify Complexity (added to her Lore to determine her "no-prep" rituals) or Control. Alternatively, you could have them set up to increase the Strength of her potions/teas.
Second, the maximum number/power of the bonuses a Focus Item provides is limited by a character's Lore. So she would need to split those +2's into separate items
But with that out of the way, I love the concept.
Finally, I don't know if it's what you're looking for, but...
Tea of Relaxation
Duration: One Scene
Opposed by: Target's Conviction
Effect: Superb (+5) effect to maneuver the sticky temporary aspect Relaxed onto the drinker.
Variations: Any kind of emotion-nudging potions; use additional potion slots, or invoke aspects, to increase strength.
Place of Peace
Type: Thaumaturgy, Tea Ceremony (for a broader approach, either Wards or Transformation, I think)
Complexity: 5 shifts
Duration: One scene
Effect: Targeted location gains the temporary aspect A Place of Peace. Anyone attempting violence must succeed against a Great (+4) effect to overcome the aspect. (not sure how kosher this is...)
Variations: Treat it as a straight-up Superb (+5) block/ward against violence, rather than an aspect, lasting for a day.
