Deathclaw control scrambler

The deathclaw control scrambler is a miscellaneous item in the Fallout 3 add-on Broken Steel.

Background
An prototype device made by Scribe Vallincourt, the deathclaw control scrambler is a modified standard transmitter that can override the Enclave's Deathclaw control signal. The device is constantly broadcasting its override signal, meaning that the device passively takes control of the Deathclaw with out any action taken by the carrier. Vallincourt provides the device to the player for testing during Shock Value to assist them in entering Old Olney.

Location
Obtained from Scribe Vallincourt during Shock Value.

 * Shock Value: The scrambler automatically turns any Enclave-controlled deathclaws friendly as long as the Lone Wanderer is within range of the transmitters of the domestication units. When the Lone Wanderer is going out of range, the device will first start to beep periodically and finally, the deathclaw will die.

Behind the scenes
The Pip-Boy image is identical to the device used to control brainless Spock in the Star Trek: The Original Series episode "Spock's Brain."

Bugs

 * After fast traveling or simply entering into a new location there is a possibility that an Enclave controlled deathclaw will spawn very close to the player. This can happen instantly after you get the device. The deathclaw will always attack anyone who's not a part of your party regardless of their disposition to you. Known locations where an Enclave controlled deathclaw has spawned/followed after fast traveling or by simply entering a new area: Megaton, the Vault 101 entrance, the Museum of History/Underworld, Canterbury Commons, the Citadel, Warrington station, Point Lookout, The Pitt Downtown, and entering the HQ of Reilly's Rangers.
 * The controller may turn a deathclaw friendly towards you, but it will not become hostile towards nearby Enclave forces. Instead, the deathclaw simply returns to its cage and completely ignores any combat between the player and Enclave forces. The deathclaw does attack creatures, raiders, or Talon Company mercs that approach near it.
 * Mind-controlled deathclaws will sometimes not even leave their cage when interacted with.
 * The friendly deathclaw will suddenly die when the Lone Wanderer enters or leaves a location.
