is there an easier way to defeat fafnir in ffxii?

Answer 1

When you enter the area with Fafnir, run past him and go to the other side of the big rock. Position yourself between the rock and the stream, out of reach of Fafnirs physical attack range. Unable to use physical attacks, Fafnir will only use status magicks and his Shock attack... which can be reflected. Equip everyone with either Mirror Mails or Ruby Rings, stand in that position, and you win. To speed it up have everyone cast Thundaga on themselves, which will reflect three times onto Fafnir. Fafnir will go down in minutes.

Refer to this video for the positioning:
