The very definition of the purview marvels say that they aren't concrete, which is one of the major shifts from 1st ed to 2nd: Embracing abstract versus crunchy rules.
A Scion who masters a Purview may wield divine authority
over it, performing acts of divine power that shape,
summon, or influence their Purview through her Motifs.
These marvels are flexible and free-form powers compared
to Boons and Knacks. If you want to perform an act of divine
power, and nothing else on your character sheet allows
it, marvels exist to let you do it.
The nature of your marvels and what you can do
with them is determined by the two elements that go into
performing them. One is the Purview used to perform
the marvel, whose power, substance, or symbolism you’re
drawing on or manipulating to shape the World to your
will. The other element is a motif, a magical paradigm or
set of metaphors through which you explain how you
control your Purview to achieve the desired effect. Most of
the time, you’ll use the Motif associated with the pantheon
you belong to. Relics also have their own motifs, which you
can call upon when you perform marvels of the Purviews
associated with that Relic. Finally, it’s also possible to gain
motifs from miscellaneous sources, such as a sacred animal
chosen through the Beasts Purview
A word for the Storyguide — don’t let the game grind
to a halt as a player tries to figure out if they can get a
certain marvel out of a Purview or motif. It’s better to let
a conceptually shaky marvel through than to sit around debating
semantics instead of playing. You can “balance out”
a thematically shaky marvel by applying a Complication
to the action it benefits or imposing a thematically related
drawback on the player’s character.
The main limit is that your pantheon's motif may require a certain "flavor" to be present in how you make it happen.
- A Scion of Ares may beckon for Ares himself to confer the *Blessing
- A Scion of Susano-O may claim the wind/air kami carried him from the ground
- A Scion of Hel can scratch runes into the dirt at their feet
The goal is to give the players some agency and allow them to telegraph as much or as little as they want of their abilities.
