Mina, and her weapons Heilagrbrandr, the sacred blade, and Myrkrbrandr, the blade of darkness.
The orichalcum orbs do most of the magick.
Myrkrbrandr can generate spheres of pure darkness, absorbing energy attacks and repelling physical.
Heilagrbrandr generates beams of light that can stun, blind, and otherwise dizzy an opponent, can disarm an opponent if aimed correctly.
Both of these cannot cause direct damage by themselves. However, if she lauches and beam from Heilagrbrandr into Myrkrbrandr's orb, they collapse into themselves, causing an explosion.
