You say that but when I look at that many numbers gathered in one place my eyes just kind of slide off.
My question with the rose field had more to do with why it grows faster the bigger it gets. The DnD spell has a set radius of destruction so it's not particularly helpful in that regard.
Sorry if this is annoying you. I'm trying to puzzle through the mechanics of the move not find problems with it.
The thing is that Epic Spells can be tweaked to the user's taste, at the cost of making them hard to cast, the actual ones in the book are just guidelines for how the math of D&D works for epic level stuff (a quick tip, it's broken as hell). Like I said, I used that as a guideline to see if people understood it better. Don't care for the numbers but the description, is more proper in this case.
And to answer the second question, that's just how exponential math works IRL. The bigger something is, the easier it's for to get bigger. It's all around us the whole time. For example even the sun began as a speck of dust floating in the interstelar gas some day, or like how, if you let a bush and then two and then three, so on and so forth grow in one place, soon enough you'll have a forest. Even something as simple as a snow ball rolling down a hill, gets bigger the bigger it already is (because it has more surface area to gather more snow). Even economy, after all, the richer you are, the faster you get more money.
If you want a small lesson in differential equations, I can explain this even further, an show you the basic equation that can be used to describe almost any exponential growth/decrease (after all, the contrary is real here as well). It's not 100% precise in all cases, which is why there are tons of especial applications for each area, but the base equation from where all others differ is one and the same.
That said, I have to go to college now, to I don't have much time to explain this in detail now. I'll leave you with a video that, while only partially related, offers an extremely powerful insight on something anyone dealing with management of any form and of any resource learns sooner or later:
Life is weird...
And yeah, I love V-sauce.
