After Watching Witch Hat Atelier, I would like to see if we can use Glyphs to create shapes, or creatures to make it more mystical. Using Form Glyphs which defines the shape of the spell followed by element and then any of glyphs you want. It's mainly aesthetic to make the Mod feel more magical. That way its attack spells don't just feel projectile based.
I feel like being able to summon a bird of light or water. a spell that falls and turns into a flower as it explodes.
I feel like it would allow for more freedom in what spells you create and the use case for them.
