So, i've returned from nearly a year. I see my Shillien Elder has a few new skills. One of which is called Invocation. It requires Spell Book: Invocation.
Seems a worthwhile skill to attain, problem is, i've searched quite a bit and have yet to find the spell book and where it's location could be found.
So..next step is to ask here, so where do you find the spellbook: Invocation? Thanks for your help.

Spellbooks (and one Blueprint) for the following skills can be purchased at the Rune, Goddard or Ivory Tower spellbook shops. Players have a chance to buy them every hour.
