Title is nice and vague. I do NOT have SA upgrade so don't say check that way. I've been using a handy program that tells me "generically" how many imbuing ingredients I need for a given mod. But I am unclear about how much I would need if I am upgrading an existing property. For example, I know that 25 ep on a ring costs: 5 essence, 10 citrine, and 10 crushed glass. I also know that 15 ep on a ring costs: 3 essence, 4 citrine But how much does it cost to upgrade from 15 ep to 25 ep? Is it the same amount as 25 ep above? Is it the difference in ingredients between 15 ep and 25 ep? Thanks in advance for any help.
