You'll Blind Somebody

You'll Blind Somebody is a perk in Fallout: New Vegas.

Characteristics

 * This perk has to be earned(like the Bug Stomper or the Animal Control perks) to obtain.

Effects

 * Awards 100 XP

Bugs

 * The challenge gets stuck upon reaching the 4096/4096 goal and after that every single energy weapon headshot for the rest of the game triggers the XP award and displays the achievement message without actually marking the challenge as complete.
 * Similarly to the PC bug, this challenge may never complete, instead upon reaching 4096/4096 it will simply reset to a lower value. Unlike the PC bug however it does not seem to be possible to get infinite experience (or any at all) from this challenge.
