Divine Power for ceremonialists

Hey everyone! I had a question regarding how much ceremonial spells costs for the purpose of calculating Divine Power. My Loremaster just hit level 5 and doesn’t have much in the way of ingredients. So getting a congregation is a must for churning out some potions and scrolls. I saw that eldritch spells weren’t given a market availability intentionally, but how else can know how much divine power I can generate for crafting?

Treat the cost of eldritch ceremonies as identical to the cost of divine spells.

Awesome! Thank you so much!
