Erinyes were high-ranking devils whose heavenly appearance belied their wicked intentions. Often resembling Celestials, they generally stood around 6 feet tall and possessed glowing eyes and large feathered wings, which they could use to fly. Although naturally female, erinyes could appear as idealized versions of the sexes of any Mortalkind.
Erinyes had powerful charming abilities causing those they looked upon to obey their every whim, or to stoke terror into the heart of any who looked at them. Their domination was so complete that the victims were willing to protect their enchantress even at the cost of their own lives and obeyed their orders without regard for the lives of others. They had Truesight and possessed abilities to disguise their form, and could call upon weaker devils for assistance.
Erinyes possessed legendary combat prowess, and could expertly wield practically any weapon. Conventionally, they often carried a Rope of Entanglement to entrap foes, alongside magic bows and swords. Through the brutality they inflicted on the battlefield, erinyes renewed the vigor of their allies, often engaging multiple enemies at once with unbridled rage. Despite their fearsome wrath, Erinyes were also tactically adept, coordinating with others of their kind to surround groups of enemies as opposed to merely flanking them.
Unlike almost all other devils, erinyes were capable of entering the mortal world of their own volition, and used this ability to collect mortal souls. The traditional method used to achieve this goal was through seduction, in a similar matter to an Incubus or Succubus, using magic to disguise their wings. They entered the mortal world alone, as they were incapable of bringing others with them, and searched for mortals that they could lure back to the Lower planes. When seduction was not sufficient, erinyes could still capture mortals through devilish bargains for martial prowess or arcane power.
