As an old school D&D player, I love the idea of the spell book. Some people says the draw of cards from the spell book makes them feel like an apprentice more than a master mage. I think of it more as draw and using all the spell componets to cast the spell. really getting into the roleplaying of MW. To make it more thematic I modified a spell book for the huntress (JBM).
I took pieces of rough suede and hand sew them together, then wrapped it around the cover of the spell book. I then made a panther paw print and placed it on the back cover. I tried to use a sodering iron and tried to brand the MW logo on the paw print. finally I hand cut a leather strip to bind the spine of the book.
So far I have created 6 custom spell books, each to a specific mage. Thought put into what each mage would want in their spell book and why. The pics of my custom spell books are too big to upload now, I have to take new pictures when I have time so I can upload to show them.
