First of all, the "new character" is actually pointed out to the person in black orb thing; the girl.
It's possible that we might get a debuffer/disabler/super-support out of her; for the heal factor, definitely plausible but needs some sacrifice kind of mechanic just to pull it off. So basically, we might get like a "rune using" skill archetype much like that of the Dragon Knight in RO.
That's my analysis on her
