Wow, so many replies in so little time, I'm surprised and impressed.
I'm beginning to get a better grasp of how arcanima works, thank you everyone^^
One question though: does the arcanist create the geometries themselves or are they merely copied from some already existing source, copy-paste style?
If the arcanist creates actually writes in their grimoires, that opens up the option of discovering and creating new spells, right? A sufficiently skilled arcanist could figure out a new pattern to use, or improve on an old one. That would be cool, certainly more interesting than simply being handed a new spell from a soul gem.
