If you guys payed attention, you would notice that she gained all of the abilities of her sacrifices: Fighting ability from Warriors, ability to heal herself from Healers, knowledge and plotting from Philosophers, and BEAUTY AND INNOCENCE FROM VIRGINS.

Not sure what ability Guardians have but I guess we're about to find out since she hasn't started sacrificing them yet. But we saw her human form in Ep. 1 and the Virgins Sacrifices didn't start till Ep. 2.
