Crafting Manuals and Librams

[Thurin]

So I've got a PC with Craft Wonderous Items who wants to craft a Manual of Quickness of Action:

Book, Manual of Quickness of Action

Aura strong evocation (if miracle is used); CL 17th

Slot —; Price 27,500 gp (+1), 55,000 gp (+2), 82,500 gp (+3), 110,000 gp (+4), 137,500 gp (+5); Weight 5 lbs.

Description
This thick tome contains tips on coordination exercises and balance, but entwined within the words is a powerful magical effect. If anyone reads this book, which takes a total of 48 hours over a minimum of 6 days, he gains an inherent bonus from +1 to +5 (depending on the type of manual) to his Dexterity score. Once the book is read, the magic disappears from the pages and it becomes a normal book.

Construction Requirements
Craft Wondrous Item, wish or miracle; Cost 26,250 gp (+1), 52,500 gp (+2), 78,750 gp (+3), 105,000 gp (+4), 131,250 gp (+5)

After looking at the prices and crafting costs, it's apparent that they all include the material cost for casting 1 wish per plus. Now with the casting rule that you can ignore an items prerequisite if you add a +5 to the crafting DC, you can ignore the wish requirement, and reduce the cost by the 25,000gp material component cost for the spell.

So lets start with the +1 Manual, if I ignore the wish requirement, I can craft the book for 1,250gp with a DC 27 Spellcraft check. This feels off to me, but seems to be RAW.

Would you add another +5 per wish spell that you do not cast for the +2-+5 Manuals? i.e. able to craft a +5 Manual for 6,250gp with a DC 47 Spellcraft check, or would it remain a DC 27 Spellcraft check since you are only ignoring the single prereq for wish?

This seems very, very cheesy to me, but RAW.

The prerequisite that you can ignore is knowing and being capable to use the wish spell, not the material cost of the spell.
The cost of creating a manual or libram use this part of the crafting rules:

In addition, some items cast or replicate spells with costly material components. For these items, the market price equals the base price plus an extra price for the spell component costs. The cost to create these items is the magic supplies cost plus the costs for the components. Descriptions of these items include an entry that gives the total cost of creating the item.

Taking the +5 you bypass the need to have wish or miracle as one of your know or memorized spells but you are still replicating them so you still need to pay the material cost.

Thanks Diego. I knew it didn't sound right, but I guess I didn't place it with that rule since it wasn't obviously replicating the spell.
