The petitioner of this hunt is Ieeha from Mt Bur-Omisace. Go there and talk to Relj. Ieeha couldn't wait for help any longer so he went to fight Fafnir by himself and he didn't come back.
about 1 155 000 HP
Resistant to Libra,
Vulnerable to Thunder
The enemy can be found in north-western part of Silverflow's End in Paramina Rift, but he appears only during heavy snowfalls. Leaving the Bur-Omisace such snowfall will be lasting. Now all you have to do is to get to Fafnir, but remember - you CANNOT pass through Frozen Brook area, because this will disable the snowstorm.
Fafnir has really considerable amount of HP and his attacks despite they're not very varied, they're very strong. Except for Rake he uses White Breath which deals Ice damage to everyone in front of hi, and may cause Stop. He also knows Shock, which inflict massive damage to one hero, but he starts using it after he had lost about 50% of his HP.
For this fight use character with Masamune, Genji Gloves and Genji Armor, cast Bravery, Berserk and Haste on him and let him play. Just keep an eye on his HP level. The second character should be a white mage, which will be occupied with healing. A Rose Corsage is a must-have for him during this battle to save him from Silence. You can also give him a bow and Lightning Arrows. As for the third character - I leave the choice to you. It can be a black mage using Thundaga, or fighter using short ranged weapon.
Before the fight prepare a stock of Chronos Tears, because they'll come in handy for sure.
After you kill the enemy you'll find a Ring of the Light. Take it to Relj and collect your prize from her.
Bounty: 7000 gil, Assassin's Arrows, Teleport Stone, Fafnir's figure in Sky Pirate's Den
