The Phase Spider Matriarch is big.

Not big in the way that a horse is big, or a bear is big. Big in the way that a fundamental error in the natural order is big — too many legs, too many eyes, a body that fills the cavern ceiling like a living tumor. She squats at the center of a vast web network, her abdomen pulsing, her legs working the silk with the idle precision of a weaver at a loom.

The web network spans the entire cavern. Silk anchor strands connect every platform, every stalactite, every ledge in a complex, three-dimensional grid. The Matriarch sits at the hub — the center point where all strands converge.

Gale launches into a tactical plan. It's a good plan — thorough, multi-staged, involving flanking maneuvers, elemental countermeasures, and a very detailed analysis of Phase Spider behavioral patterns that he delivers with the enthusiasm of someone presenting a doctoral thesis.

"Phase Spiders can shift between planes," he explains, fingers tracing invisible diagrams in the air. "She'll blink to another platform the moment she's threatened. Our approach needs to account for a minimum of six possible teleportation destinations, each requiring a separate containment strategy that —"

"Hey, Gale."

He stops. Blinks. "Yes?"

"What happens if there's no platform to blink to?"

He stares at you. Then at the web network. Then at the platforms — each one anchored to the cavern walls by silk strands. Each one dependent on the web network for structural support.

"You cannot possibly —"

You step forward. Extend your arms. Trace Gale's geometric containment pattern — but wider. Not a triangle. A circle. A full three-hundred-sixty-degree containment field that encompasses every anchor point in the cavern.

It's the biggest kinetic manipulation you've ever attempted. Your temples throb. Your vision narrows. The containment geometry strains at the edges, trying to collapse, and you hold it through sheer stubborn refusal to let physics win.

Kinetic Squeeze. Not one strand. All of them. Simultaneously.

SNAP — SNAP — SNAP — SNAP — SNAP.

A rapid cascade of severed silk, each cut clean and precise, each anchor point releasing its grip on the cavern wall. The web network trembles, sags, and — with a sound like a thousand kites losing their wind at once — collapses.

The Matriarch feels it. She reacts instantly — legs gathering, body tensing, initiating the phase-shift that will blink her to safety. She flickers — partially translucent, half-here, half-somewhere-else —

But there's nowhere to go. Every platform is falling. Every anchor is severed. She blinks to where a ledge was and finds empty air.

The web, the Matriarch, and every platform in the cavern plummet into the bottomless Underdark chasm in a slow, billowing cascade of silk and chitin and flailing legs.

The roar of the collapse echoes for a long time.

In the silence that follows, a pulsing Dark Amethyst gem clatters free from the wreckage of silk that caught on the cavern lip, rolls across the stone, and stops at your feet.

You pick it up. Tuck it in your belt.

Gale stares into the chasm. Stares at you. Back at the chasm. His mouth opens and closes several times.

"She just defeated an apex subterranean predator," he says faintly, "by removing the entire battlefield from existence."

"Structural engineering," you say. "Also, physics."

Lae'zel, from the rear of the group: "Efficient."

Coming from her, it's a standing ovation.
