Fiend Arena Oversoul
Balivarha has relatively good all-round stats and the ability to absorb Fire, however, any non-Fire magic will serve well here. Armor Break drastically reduces its high Defense, and equipping Fire-absorbing equipment, or using a Lunar Curtain/Light Curtain, casting Shell/Protect, and using high Defense dresspheres, will help mitigate the damage it can deal. It is generally not too tough of an enemy.
Fiend Tale Edit
In the Fiend Tale endings, a notable Balivarha was a good-for-nothing who was selected to represent the Ruminants who attended a peace conference between his kind and the Drakes represented by Spine Drake. It turned out to be a trap by Yevon monks to pit the two fiend-types against one another. Divebeak, Vertigo, and Barbuta revealed the treachery, and Balivarha and Spine Drake join forces against their common enemy.
