There is no doubt that the six Spirit Avatars currently chanting [Immortal Spirit Six Circles] are indeed as Reiger previously mentioned, belonging to the magic-specialized type, much like the plant type that appeared on the 59th floor of the underground city.
The upper half of the Spirit Avatar resembling a woman can chant magic, and the three ugly faces of the monster's lower half can also chant magic. Coupled with the countless magic circuits forming an array around them, this Spirit Avatar is even more adept at using magic than the plant type that previously appeared on the 59th floor of the underground city, and its strength definitely surpasses the two Spirit Avatar types of oxen and giants.
Her category level is at least Lv.7, maybe even Lv.8, and her firepower exceeds her level by far; like Rephia and Revilia, it's easily beyond one level, possibly even two levels.
