Sentry's Fibrous Cocoon

The sentry extrudes this hard, web-like fibrous material, encasing Dirgo completely and killing him instantly through immobilization and suffocation. A second instance neutralizes Wesley's phaser. Composed of dense, selenium-laced fibers, it forms rapidly in response to threats, leaving Wesley horrified and weaponless in the cavern.
