Scroll Amanuensis

You can copy spell scrolls without issue, even if you cannot cast the spell. You need to have the scroll with you for the entire time that you are copying it, (unless a different feature gives you a sufficiently powerful memory) and the copying process takes the same amount of time and money as scribing the scroll yourself.

When you are making a scroll of a spell that you know the GP cost of the scribing process is reduced by half due to the efficiency of your writing.
