A Thamumaturge with the scroll esoterica feat chain gets to make temporary scrolls daily.
A: Do you need to pay the usual GP cost to do so, under crafting scrolls . Considering the effects are to give you more versatile but lower level spells per day than a spellcrafter dedication and the fluff says the parts come out of your esoterica scrap, I doubt this is it, but then that leads to followup question:
B: If the spell would normally have an expensive component cost, do you need to provide it or do you get that for free (too)? Normally that's paid at the time of the crafting of the scroll, not sure how it works if they are making free scrolls.
