Horned Devils are quick; even faster than their Gargoyle counterparts, and can attack up to four times per round, with their physical attacks inflicting Paralysis. In addition, they are capable of casting Fire, Fira, and Hold spells. They have elemental resistances to both Fire and Ice, but due to their low HP and physical Defense, they can be defeated easily with one or two hits. However, they have a relatively high magic resistance, making it a waste of effort and MP to use magic against them.
They later appear again in the Citadel of Trials. This time around, they are more of a nuisance than a threat, as the party should be at a fairly high level.
They are a palette swap of the Gargoyle enemy; Horned Devils are coated with red skin and green wings, unlike the blue-colored Gargoyles.
