Beta Wave Emitter

The beta wave emitter is a world object that was added to Fallout 4 by the Wasteland Workshop add-on.

Crafting
A beta wave emitter requires 1 unit of power to work and is effective throughout the whole settlement it was built in.

Characteristics
Beta wave emitters are meant to control wasteland creatures and animals captured in cages. Any released creature under the influence of an active emitter will refrain from attacking the Sole Survivor, their companions, and any resident settlers but will still occasionally attack other tamed creatures that are not of their own species. Any survivors will then prowl the area and defend it against outside aggressors, adding a race-specific value to the settlement's defense rating without taking up a settler slot. The creatures can therefore be used as a mobile defence force of varying power.

Creature defence ratings

 * Brahmin: 0
 * Cat: 0 (boosts settlement happiness instead)
 * Deathclaw: 10
 * Feral ghoul: 4
 * Mirelurk: 6
 * Mole rat: 4
 * Dog: 4
 * Mutant hound: 5
 * Radroach: 1
 * Radscorpion: 7
 * Radstag: 0

These numbers are independent from the respective creatures' subtypes - a mythic deathclaw adds the same value to the settlement's defence rating as a basic one, but will of course be much more powerful in actual combat.
