Resonance (霊応力 Rei no Ryoku?) is a special term in Tales of Zestiria and Tales of Berseria. It gives one the innate ability to perceive seraphim/malakhim, and malevolence.
History[]
Tales of Zestiria[]
A majority of humanity lacks the necessary resonance to perceive the seraphim. Although, a small minority of humans, with at least enough resonance, can hear their voices. Humans who can actually see the seraphim tend to have more resonance than those who can only hear their voices. Also, higher resonance is required to recognize the seraphim than to recognize hellions. For this reason, while there are many legends about monsters and demons, there are few legends about the seraphim.
