I got a lot of Questions about the fgr bosses and where they spawn... So i decided to start this thread (its easier to send a link thank explain it again and again and again)

Distichous Mongrel:
(Near the Capella spawn)




Virulent Cauda:
(Near the Reddish Couda, in the middle of the big desert)





Ancient Cockatrice:
(At the Nasty Ruins - try to dash trough then u know why i call them NASTY)





Monakus Karion:
(Next to the Temple)




I hope i could help some guys with this... have fun with hunting them
