Shielded Tome Feat 6
Source Pathfinder Impossible Magic
Prerequisites Raise a Tome
You can magically fuse a shield into your favorite book during your daily preparations or as a 10-minute activity with the manipulate trait. The shield appears in the book as an elaborate bookmark. The fusion lasts until you fuse a shield into a new book or the book is out of your possession for 24 hours. While the two are fused, the book shares the Hardness, Hit Points, and Broken Threshold of the shield.
The fused item has the shield's activations and benefits (such as a Spellguard Shield's bonus to saving throws against magic), and it can still be consulted as normal for purposes like Recall Knowledge and the benefits of Raise a Tome.
If the shield or your spellbook is etched with a reinforcing rune, the fused item gains the rune while they're fused; if both have the rune, the highest-level rune applies.
