Archmage Inalla's Ink & Quill

A personal tool created by Archmage Inalla, head of the mages guild of Onoa. 

The inkwell refills itself one week after each use, and the quill appears to have been fashioned from the feather of a sphinx and is fairly oversized for writing purposes.

Using this ink and quill set, a wizard can copy a spell (provided it is on the wizard spell list) from a spell scroll or another wizard's spell book into their spell book in 10 minutes and at no cost, regardless of the spell's level. This can be done once per week.
