Need all of you pros again..
im stuck finding this fafnir....i mean i know its located at silverflows end - paramina rift..

problem is..the marks only appears when the the map is in blizzard...but everytime time i enter the map..it is not in heavy snow..tried to re-enter the map...entering from other region also cannot.zzzz

this is my last hunt to complete all....

eerr:why the hell square makes vaan as the hero when balthier acts more like a hero and ashe fall in love with hiM?in the end? Duhh

Ashe and Baltier ? Aren't him and Fran an item ?

And Vaan "is spoken for", at least that is what the Viera at Rabanastre says ;)
