Euryphaessa (Reference)

Euryphaessa means "wide-shining" and is named after Theia (Also called Euryphaessa) Greek Goddess of sight and brilliance.

Euryphaessa can curse people, but not kill them directly with it. She has to draw blood from the victim first.(like a slap with her long af clawed hands). The wounds from that never seems to heal properly, scarring is an odd shimmer, and the victim(s) hears whispered voices at night cursing them with "may your arrow never aim true" kinda curses. Other effects of curse are twisted to suit each individual.

A silly fact, but 'Phaessa mains Kirby in Smash Bros.
