That is a good point on magic. There used to be a Casting roll, but I didn't like it much so I tossed it. Reading through it again though, I think it should swap crafting to +INT. I may make it +DEX or +INT, whichever is higher. Thanks for pointing that out.
Sorry, but all magic is crafted. Low fantasy setting. However, it does often require runes, ritual phrases, or actions. They don't just happen.
Curses last kind of whatever you feel is appropriate. I had just been rolling on the potions table for duration.
I had considered the transcribing so you could use it to learn the spell later, but it's up to you.
Thanks for pointing all this out!
