Chapter 1 - Non-weapon Proficiencies
Bookbinding Non-weapon Proficiency
A wizard with this skill is familiar with the process of assembling a book. Bookbinding is a demanding task; the pages must be glued or sewn to a common backing of some kind, protected by various kinds of varnishes or treatments, and then fastened to a strong and durable cover. Additional chemicals or compounds to ward off mildew and deter moths and bookworms are a necessary precaution.
Bookbinding is especially helpful for a wizard assembling a spell book. Normally, a wizard must pay a bookbinder 50 gp per page for a standard spell book, or 100 gp per page for a traveling spell book—see Chapter 7 of the DMG. A wizard who does this work himself reduces these costs by 50%, although the process takes at least two weeks, plus one day per five pages. If the character passes a proficiency check, his spell book gains a +2 bonus to item saving throws due to the quality and craftsmanship of the work. In addition, the wizard must succeed in a proficiency check if he is dealing with unusual or unsuitable materials, such as metal sheets for pages or dragon scales for a cover.
