Castlevania: Dawn of Sorrow
An Erinys, like the Valkyrie, wields a lance and a shield. She has a pair of wings that allow flight. She also wears Norse Armor, a Norse Helmet and Norse Boots. Erinys wears a large loincloth that covers her lower body. She attacks by lunging her giant lance at an enemy and has the ability to yell loudly and damage all in range. Some Erinys also pledge loyalty to a Stolas Owl, that summons them and a Flame Demon when the Stolas draws out a magic circle of respected angel or demon. Both the Erinys and the Flame Demon are very reliable Red Bullet Souls. Due to her being a fallen angel too, Soma will have extreme difficulty "catching" her with his Power of Dominance. Dominion of her soul allows Soma to summon Erinys as a Red Bullet Soul. She cost 45 MP to summon and when commanded, Erinys, with a beautiful long and blonde hair and dressed in white dancing dress, will appear with a white wings and sings a note that does divine damage to all that is in her way. Though MP for MP she is not as strong as the other souls, Erinys can hit her enemies twice and she is very fast to attack. She also gives Soma a temporary shield effect due to her casting covers Soma like one. Erinys is among the rarest of souls to cast Holy damage to enemies aside the Valkyrie's soul. This puts her on par with the other powerful bullet souls in terms of power because she can do 1.5 times more damage to enemies weak to Holy Damage. Erinys is valued by most players in Boss Rush due to her incredible fast casting time, her divine damage potential and the shield effect. Erinys Soul cannot level up even though multiple of the same soul is collected. Soma can also allow Yoko to pull Erinyses soul out of Soma and fuse her with a Geiborg spear (obtained by fusing a Broniac with a Slogra) to create a Longinus Spear, though described as a divine spear, it cannot give divine damage. The Longinus Spear allows Soma to hit enemies three times when he use MP burst for the spear.
