The Hunt for Braegh becomes available after you complete the events at the Stilshrine of Miriam and defeat Judge Bergan at Mt Bur-Omisace.
Travel to the Babbling Vale area of the Mosphoran Wastes (or warp to the orange Save Crystal). Va’Kansa, the petitioner, is a green Bangaa standing next to Luccio, the shop owner.
Braegh is located in the western area of the Salikawood in a zone called the Corridor of Ages which is actually fairly close to the entrance to the Necrohol of Nabudis. Travel to the Corridor of Ages area heading west through the Grand Bower and you will immediately see Braegh flowing from the top level of the platform as you enter the Corridor of Ages area.
Level: 35
HP: 43,283
Steal: 
Storm Magicite, Storm Crystal, Grimoire Aidhed
Braegh is not too difficult compared to some of the previous battles you have fought. Make sure to keep all of your status buffs active including 
Protect, Shell, 
Bubble and Faith.
One extremely helpful tactic for this battle is to reflect Braegh’s “Invert” skill back at it. Invert will switch an enemy target’s HP with its MP. If this move is reflected back at Braegh, it will reduce its HP down to 999 making the battle exceptionally easy.
That being said, because Braegh is a Rank IV Hunt, this is still a relatively easy battle. The horse is weak to Ice-based Magick and you can use 
Silence on it in order to prevent some of the more devastating spells that it casts. Equip your 
Icebrand sword and 
Sledgehammers (if you have them) as well as these weapons will do the most damage.
A video of the battle in the Zodiac Age version is included below:
Return to Va’Kansa back in the Babbling Vale of the Mosphoran Highwaste to receive your reward which includes 1,700 gil, an 
Obelisk and a 
Hi-Ether.
