When i farm Gates of Kryta on my all death owning 55 hp monk
i usually get some war tomes. So if you need a war tome and i'm online you can always try me out because i usually have at least 1 or 2 warrior tomes somewhere in a corner of my Xunlai chest ^^
It might happen i'm out tho. But you can always try ^^
