It tells you precisely that the thing you're underlining as being a clearly more powerful option than the other things on the list is also listed as having a specifically higher cost. There is no cap, just increasing costs.name_here wrote:Well, I left that part out because I don't think it's actually relevant. Yes, it tells you how the cost is assigned, but it doesn't say anything whatsoever about what items you can do it with. It doesn't even put in an XP cap that would allow you to declare that it means any item below that cap, like it does with nonmagical items.
Lots of things are uncapped and having likewise uncapped costs. Epic items, for example, have no bonus cap, just stupidly titanic costs for bonuses that are very large. The part where that goes south is the thing where there is a second rule that lets you simply not pay the cost.
This is why making the Wish argument that an at-will 9th level spell is within the guidelines is a strong argument, while the sarrukh argument that an at-will 9th level spell is a weak argument. Wish has a calculable costs for an at-will 9th level spell. It's a very large number, but it exists. That means it isn't outside the guidelines. Almost anything you'd want to do with Manipulate Form is outside the guidelines, because there aren't any guidelines to discuss.
