One of her main selling points is her Tripwire, which is extremely effective against bosses weak to HVY and debuffs.
Her base MAG isn't THAT good compared to other dedicated nukers, but it's still very viable, nonetheless. After inflicting HVY, her offensive power increases quite a bit with Final Blow.
Don't forget about MAlice Cannon (buffs her MAG) and Doll Guard (Very high evade).
She can target both defenses with her attacks as well, though I usually use her for her single-target FIR nuke (Artful Sacrifice).
I'm sad as to how there are no physical MYS attacks. There's a magical PHY attack, why can't there be a physical MYS attack :<
