Hunt 35: Crime and Punishment
Orthros - Rank V
This Elite Hunt is available after the events at the Tomb of King Raithwall and after you have reached the Clan Rank of Headhunter. You receive it early in the game, and it becomes much easier to defeat later on.
For example, you will likely want to have the 
Bravery, Faith, and 
Bubble spells as well as Protect, Shell, and 
Haste. The best time to complete this Hunt is after you defeat Judge Bergan on the second visit to Mt Bur-Omisace.
Petitioner
You can find the Contrite Thief in the Lowtown of Rabanastre. The Contrite Thief is near the entrance to the Garamsythe Waterway, lying on the ground.
Mark Location
Orthros is in the Southern Sluiceway of the Garamsythe Waterway. It is very close to the location where you may have already fought White Mousse.
To make Orthros appear, you must switch your party around so that you have all female party members when you enter the Southern Sluiceway. You can immediately switch your party members back around, though, once Orthros has spawned.
Hunt Battle
Level: 34
HP: 87,141
Steal: 
Phoenix Down, 
Caramel, Slime Oil
The most challenging aspect of this fight is finding ways to do enough damage efficiently to Orthros. Physical attacks, while not completely useless, are much less effective against flan-type enemies like Orthros. You can use Bravery to increase the amount of physical damage dealt, which helps.
The best tactic is to begin the battle with Bravery, Faith, Protect, and Haste Magick activated. You should also keep 
Blind active on Orthros throughout the fight. MP can become an issue later on in the fight, so save your heals and use them efficiently. You can set up a second party member to assist with healing later on in the fight.
Orthros has a few attacks, including Mythril Bubbles, which inflict negative status effects such as Slow, Blind, and Immobilize. Make sure that you have an Esuna Gambit set up on a couple of your characters.
You will receive a bundle of 
Stolen Articles at the conclusion of the fight.
Return to Contrite Thief in Lowtown to receive your reward, which includes 3,800 gil, Horakhty’s Flame and Unpurified Ether.
You can now complete a part of the Three Medallions side quest. A man named Samal will appear after you speak to the Thief and will give you the Blackened Fragment. This Fragment is part of the Three Medallions side quest.
This Hunt takes place during the intermission period in Rabanastre following the events at the Stilshrine of Miriam. Return to the Rabanastre Walkthrough page when you’re done with it.
