So I took the time to reread the text which breaks down the process of creating a seedspell.
I'm very impressed by the amount of work invested in this. It also got my juices flowing and made me go back to what I was trying to make myself. I'd soon write down something and you're invited to look at it, if you have spare time.
Regardless...
There are places that I found overly convoluted and unnecessary (your mile may vary).
If you go under the Emanation or Area titles; what's the difference between a bolt and a beam? or a stream? A cone AND a quadrant? Why does a dome cost more then a sphere? Also spread, cloud and burst (and sometimes Nova). Basically I argue that all of those can be reduced to some basic bolts.
I also didn't understand the functionality of Arc.
Also, for me personally, I tend to keep both descriptive (i.e. flavor) and informative text separate in a clear way. It's always nice to read a story, but when you have to go fish for numbers and formulas inside a wall of text... but that's just me.
Cheers.
