Pet Skill - Amour Piercing Book

[Chillidog]

Hey guys, I was wondering if there is a pet book to upgrade this pet skill - Amour Piercing

I've struggled to find it on sale in any market, it doesn't appear in the list of book you can get from the relics (Black dragon coin) and I've never got from the wishing well.

Perhaps the book has a different name to the skill???

Cheers

Actually there is book for that skill, name is: [Pet - Armor Piercing II] and yeah the book is DAMN rare.
