The hero reacted in an instant, releasing a half-dozen blue sparks from each hand.  They grew until they were each three feet across, crackling with electricity, moving at a walking pace as they slowly homed in on Trickster.

He had to teleport to avoid the closest one.  Only some of the orbs followed him to his new destination, the others remaining where they were.

...

Trickster teleported again, trying to maintain distance, but Eidolon had created more of the sparks, and the things were spreading out evenly across the battlefield, moving closer to Trickster if he got within ten paces of them.

...

She crashed into the first of the lightning orbs.  She felt the current surge inside her, settle in her bones, latent.

A heartbeat later, every single orb that Eidolon had cast out flashed with visible arcs of electricity, striking her.  The energy ripped through her, stripping flesh from around the bone of her arm, her ribs, her spine, and the larger bones of her lower body.  The electricity surged to the ground and out the top of her head, stabbing toward the sky in a visible lightning strike.

...

She touched another, and it was worse, drawing on the residual energy from the first contact.

The third was worse still.

She’d complained of the sheer heat of this body before, but this… it was heat and pain on an inhuman level.  Transcendent.  Were she regular Noelle, Noelle without the powers, without the monstrous lower half and warped brain, even a tenth of this would knock her out, stop her heart from the sheer intensity of it.

On contact with the fourth orb, her frontmost legs collapsed under her, with everything within a half-foot of the major bones being rendered to little more than ash.  There was nothing to connect flesh to bone, and she toppled.

She roared, and for perhaps the second time in the past hour, both she and her monstrous half were in agreement.  With her other legs, she pushed herself forward, and extended one of her long tongues for the orb closest to Trickster.  To Krouse.  She screamed in pain and fury as it ripped through her, and another bolt stabbed toward the sky.

...

Eidolon was there, too, at the end of the street.  The glow beneath his hood and sleeves was almost blue in the reflected luminescence of the twenty or thirty orbs that hovered around him.  A further twenty or thirty orbs were spread out over their immediate surroundings.

...

Eidolon had apparently wanted to spare her captives, because the electricity had only affected her, her flesh as it surrounded her bones.  He had selected that power with their safety in mind.
