Those kind of paper talismans would be cool for onmyouji (or mystic/oracle/whatever you want to call them).

reading is for nerds!! and don't summoners use the power of crystals to summon? so why the books? unless they legit just carry around a picture book of their dog and random doodles into battle. idr smn lore tbh

Summoner: Here, I wrote down the mathematical formula for god.

I don't think crystals show up any more than other jobs. They mostly channel their own aether that kind of stores their exposure to primals. The arcane geometries extract that exposure.
Either way SMN lore is gonna have to get totally retconned.
