Here's a question, before I upload that:
Would it be worth it to separate wands and scrolls and handle them separately? I guess it would be fairly easy, now. I don't have a particular use-case... maybe some kind of technologist or luck-based kit could use wands, but actually casting spells from scrolls would still be out of bounds? Or maybe priests of Oghma or Deneir could use arcane scrolls, being so studious, but would not go around flashing wands at people?
Hmm. I suppose why not?
