This vigor was inspired by the film Rock-A-Doodle by Don Bluth, about the rooster who commands the sun to rise when he crows. At first I thought that it would be cool to make this power allow the player to summon a flash bomb or concussion grenade with a loud crowing noise to disorient enemies.
Recently, I thought of the original demo for Bioshock Infinite and I remember Elizabeth shining light on part of a bridge.
This gave me the idea that the vigor could weaken metal as well as blind enemies, which would make it highly effective against mechanical enemies like motorized patriots, turrets and handymen.
