Yes I'm here to brag... I spent all day doing Prime avatars so that I could unlock Fenrir. I finally get a group together for Fenrir after shouting for about an hour. We head out and whoop the **** outta him on darksday of all days :D. Afterwords I decide to go summon him to mess around and i think to myself I want that pelte shield. I run up to his pop spot and he's sitting there so I pop out Ramuh and kill him in 2 shots.... What do you know? 1/1! As a level 15smn/7rdm.
Good Luck to the others who haven't had such luck.
