Hellfire oni
Hellfire oni are the infernal counterparts to their demonic relative, the dread oni. Whereas dread oni are corrupted by exposure to the chaotic magic of the Abyss, hellfire oni are typically granted their unique abilities through contracts with powerful devils in the Nine Hells.
Infernal Form
At first glance, hellfire oni are often confused to be large devils since many of these oni sport crimson red skin, and devilish horns. Although most oni have the ability to magically propel themselves through the air, some hellfire oni have even been known to sprout a pair of bat-like wings. Because of their characteristics, many adventurers confuse them for fiends, using special magics and weapons designed to specifically counter them; unfortunately, only to find that they have no effect against the oni.
Agents of the Hells
Since the source of their infernal power comes from their devilish contract, hellfire oni typically maintain some level of allegiance or fealty to the Nine Hells. Although the hellfire oni typically have the autonomy to pursue its own personal agendas and goals, they often have been known to carry out missions on behalf of their infernal patrons due to their influence on the Material Plane. Because of this, hellfire oni have often been known as the source of infernal incursions as well as secret conspirators for many devilish cults.
Burning Fearmongers
Like the rest of their kin, the hellfire oni's power is fueled by the fear of their enemies. Thanks to its newly granted infernal power, the hellfire oni has the unique ability to literally use their target's fear as the source of their magic. Creatures who tremble before its nightmarish presence are instantly consumed in the very fires of hell. The only way to extinguish these flames is to overcome one's own terror.
Battle Tactics
In general, hellfire oni are extremely aggressive and somewhat reckless fighters, especially when it senses fear in its opponents. In combat, the hellfire oni typically prioritizes those frightened by it. Thanks to their blazing charge, the hellfire oni can quickly cover a lot of ground with ease to obliterate its opponents under a flurry of hellish strikes with its mace. Unlike their other kin, their fighting style is less of horrifying game of cat and mouse; but rather a brutal rampage of carnage, fueled by each opponent that succumbs to either its horrific presence or falls to its brutal blows.
Despite its brutish tactics, the hellfire oni is quite proficient in using Infernal magics using hellfire to immolate large numbers of opponents at a time. If the situation requires it, the hellfire oni has the capability of calling devils to come to its aid. The oni typically only resorts to summoning these creatures if the fight seems unwinnable or if it has an alternative goal other than its brutal hunts.
