So I know there's a table that speaks on xp costs for upgrading skills and talents, and I'm just confused on the pricing. They have a cumulative total next to them, so does that mean you pay that much when it's like, the 5th upgrade, or do you only pay that much if you upgrade 5 times in one go? I don't know if I'm wording this well at all
