Books for Collection QuestsFollow

This thread is for where we can obtain the books to do the collection quests for lore mob parts items such as the orcs. I've got some lore zombie parts that I would like to put in a collection book if any knows where one can be obtained or if it is dropped. Also any other info on any other mobs. Thanks.

1.) Orc Mastery - Book obtained inside the tower at the left side of the door at the crossroads in the Commonlands.

The Gnoll one is found in one of the keeps in Antonica. I believe it's the Gnoll Slayer's keep, right by the Steppes station.

You have to examine a box to get it. There may be a limited number available per day, as one friend was able to get it then two were not.
