The following books used to be found on specific vendors in order to help raise your skill to 350: Tailoring Eminent Cultural Symbols Tailoring Sacred Cultural Symbols Tailored Armor Step VIII Tailored Armor Step IX Tailored Armor Step X Tailored Armor Step XI Tailored Armor Step XII Tailored Armor Step XIII Upon searching the vendors in POK, Abysmal Sea and Crescent Reach, I was unable to locate any of the books, though you can find the Tailored Armor Step books 1-7 (I - VII) easily along with the books above 13 (XIII)
From another site, the first two books on symbols could be found on the following vendors: Abysmal Sea a cultural tailoring historian @ 49,103,117, near the oven behind the bar area Crescent Reach a cultural tailoring historian @ -1417, -1487, 34 Plane of Knowledge a cultural tailoring historian @ -146, 710, 2 Culturist Devari @ -314, 954, -75
From another site, the Tailoring Armor Step books could be purchased from the following vendors: Abysmal Sea a tradeskill armor historian @ 36,166,115 Crescent Reach a tradeskill armor historian @ -1430, -1500, -87 Plane of Knowledge a tradeskill armor historian @ -79.57,736.98
Since I found other volumes on different vendors, I made sure to search available vendors nearby to see if they might have the books, but was unsuccessful in my search.
Not a bug, certain cultural books are only available as you skill up. Theres a min skill required for each before it will show to purchase. I find all of those on the vendor.
Thought I was high enough in the Tailoring skill, guess I need to work on it a bit more before trying to get the rest of the books. Thanks for the information and definitely this post can be removed.
