The Dual Horn is an enemy in Final Fantasy X found on the Mi'ihen Highroad and the Old Road. A second, more powerful version can also be summoned by the Guado Guardians during the Siege of Home. These Dual Horns are more dangerous with higher HP, Speed, and Power.
Inflicting Darkness on it will make the battle easier. A good strategy is to use Wakka's Dark Attack to blind it and then attack with physical fighters. An alternative strategy for early encounters is to summon Valefor, which will easily evade most of the Dual Horn's attacks.
Kimahri can use Stone Breath to instantly kill them.
