Gavrok's Sonic Cone (including test wood destruction)

A conical device Gavrok deploys on the TARDIS exterior to demonstrate its lethal capabilities. The device is shown destroying both organic matter (test wood) and synthetic materials (TARDIS exterior) with concussive force. Its activation produces blast effects that disintegrate matter with visible scorch marks and debris, while activated by remote command it hums with contained energy. The lethal radius is visible as a distorted shimmer in the air around the beam. Gavrok uses this demonstration to visibly unnerve Delta and her daughter, underscoring its immediate threat to the TARDIS crew and bystanders.

Gavrok demonstrates devastation of sonic cone

The rough piece of hardwood serves as Gavrok’s improvised test object, snatched from the ground with casual brutality before being launched directly into the sonic cone’s energy field. Upon contact, the wood disintegrates explosively into charred splinters, confirming the weapon’s lethal potential.

Before: Loose, unremarkable fragment scattered on the uneven ground

After: Reduced to blackened debris scattered across the TARDIS exterior and scorched earth

Doctor pinpoints TARDIS sonic trap weak point

The sonic cone's lethal beam paints the battlefield with a shifting radius of destruction, dictating the constraint zone around the TARDIS. Its beam's shadowed underside becomes a focal point for the Doctor's tunneling plan, but the landed Bannermen ship makes the defense immediately vulnerable to the new threat overriding the Doctor's calculated risk.

Before: Active lethal perimeter around the TARDIS, enforcing no-go zones

After: Suddenly incomplete defensive barrier as the Bannermen's arrival forces tactical reevaluation

Gavrok steps intoTARDIS trap

The sonic cone hums ominously in the corner, its conical shape pulsing with contained energy as Gavrok crosses into its radius. Recognizing no immediate threat, he dismisses its presence and steps closer to the control stick, unknowingly breaching its lethal threshold. The cone’s activation is delayed until his intrusion, revealing its hidden precision as a defensive mechanism primed to react to intruders.

Before: Embedded near the control stick, its hum barely audible beneath the ambient tension, inactive until breached

After: Flashed to lethal activation following Gavrok’s intrusion, its destructive beam atomizing terrain and repelling the Bannermen assault
