Trails of Blood and Iron

Rowan's blade begins to emit a dark purple aura. Holding his greatsword out in front of him, he dashes forward with extreme speed and swings his sword around him in a brutal arc. A pillar of dark purple energy bursts from his sword, exploding on impact, and absorbing some of his opponent's health. The Emperor staggers back a few feet; he was clearly fazed this time.

Before the Emperor can counterattack, Raine moves first. A blinding aura of green energy explodes up around her. She unleashes a barrage of bullets from her gunblades, then charges forward and runs her enemy through again and again, her speed increasing with each pass. After the seventh strike, she charges past her opponent and stops, turning back to face her enemy.

"Frenzied Lightning Dance!"

A huge beam of electrical energy shoots from her two weapons, and detonates on impact, turning into a massive storm of lightning bolts that seem to dance around the battlefield, repeatedly striking her foe.
