While Farren moved to join Torquil and Gerlinde on the darkbeast's left flank, adding his Blade of Mercy to the onslaught of he transformed Hunter's axe and the flaming threaded cane, Ophelia finally had her chance to execute her plan. The soft glow from the lightbeast, both the part enveloping itself and extending to the darkbeast, lasted only a couple of seconds before it faded, after which the chain connecting the two seemed to become void of either beast's energies.
Seizing the opportunity she fed the Holy Moonlight Sword another quicksilver bullet and thrust it into the sturdy steel link once more, unleashing another arcane explosion. As the blinding light faded and the dust settled, she would find the chain even more bent and warped than before, with the link partially twisted open on one side – clearly on the verge of breaking apart entirely – but still just barely holding itself together.

The darkbeast's head veered momentarily to follow Farren, its empty eye-sockets glancing at him, Torquil and Gerlinde making a united front as they carved into its left side with wild abandon, yet despite their efforts best efforts could not seem to inflict lasting damage; if anything, it seemed to regenerate even [I]faster[/I] after the pulse of light that had just washed over it, as if its vitality had been restored and reinforced. Then its head veered to the right, to where Ophelia stood over its chain all alone, and had just caused a rather loud and flashy explosion to attract its attention.
With an abruptness that nearly knocked Torquil off his feet, as he only barely managed to dislodge is axe in time, the darkbeast leaped into the air. It moved with a speed, agility and precision one would not expect from such a massive creature, sending rotation in mid-air while soaring as much as ten meters over everyone's heads; a movement that, predictably, jostled the chain connecting to it significantly and jerked the weak link Ophelia had been targeting away from her some eight meters or so.
And then it plummeted back to the ground right on top of Ophelia, bringing down both of its front leg claws on top of her, both of them burning with bluish energy and erupting into a powerful electric explosion on impact.
