Energy dampening weapon

The energy dampening weapon was an advanced energy weapon used by Breen forces in the mid-2370s during the Dominion War.

The weapon was first encountered by Federation forces when the Breen entered the Dominion War as allies of the Dominion in 2375, at the Second Battle of Chin'toka. Since Federation Alliance had never encountered the weapon before, it was especially effective against them. The weapon works by draining the energy of targeted ships, disabling their engines, weapons, and shields, thus making them easy targets for conventional weapons. Amongst the vessels lost to the weapon was the USS Defiant. (DS9: "The Changing Face of Evil")
