How does Hedge Magic function? It says that it takes the normal ritual time to cast, but if you're using the incantations how can you enhance someone's attribute check if it takes a day to cast?
You take them to the sweat lodge for a day and a night where you purify them with sacred smoke and the ritual markings of the ancestors, so that when they set out on their fated quest the following dawn, they get advantage on Wisdom checks to follow the signs of the gods.
... for example.
Yeah but how long does the effect last? A scene? A day? The next Wisdom check?
it says “bless or curse an undertaking,” so in the above example, I’d rule it lasts the entirety of the vision quest.
If the undertaking were a battle the next day, it probably lasts the scene.
