Just to Clarify, I didn't say I got my Poison Cloud from an Oma Warrior, I didn't.
I got mine on PI, however this convo was mainly started about the availability of FF and the other class books, which don't seem to have dropped.
In EuroMir, new 40+ books of certain types did drop from Oma Warriors and other low level bosses, like OW's, Giant Keratoids, Ghouls, Bone Elite etc
I asked why people complaining aren't looking to those old droppers. I don't expect FF will drop on PI or in PSC like Poison Cloud, but I wouldn't be surprised at all if FF dropped from Oma Warriors in WW, or Giant Keratoids around MW, or Ghouls or Bone Elite's, and next to nobody seems to be even considering this, let alone actually killing a few.
Also Lancelot, books DO drop outside of their own level range areas. You can get 20 n 30+ books in mines, you can get sub lvl 10-20 level books in higher lvl areas.
