Forgotten Tales

Are there still any ninjas in other places then the oasis castle?
I have got an alt which needs to kill ninjas for the mercenary quest.
Problem.is that he. has lost the book you need to give to the devil or boy years ago and therefore cannot enter the oasis castle.

if i remember well, there are in ardesia city prison, they attack with also blinking mages and fire archers

tthe traitor shouting npcs spawned them, but i beleave they dont anymore since that spawn has been made lower lvl momsters to preent farming there.

I got the book now though, a friend used an alt he wasnt playing further to get it for me.

for what I saw, actually the shouters spawn low demons and maybe archers. ninjas were before entering prisoner jail, in free the brother quest
