Ravenous Hunger

Ravenous Hunger is a companion perk in the Fallout: New Vegas add-on, Dead Money, gained by having Dog as a follower.

Effect
When Ghost People are knocked unconscious, Dog will consume them, preventing them from regaining consciousness.

Note

 * This is very helpful before Dog teaches you how to properly kill them with the Ghost Hunter perk.
 * Strangely, this perk doesn't appear in the Pip Boy or in the perk menu of the G.E.C.K. (which contains all perks of the game), and appears to be an scripted action only performed by Dog and not properly a perk.
