You'll Blind Somebody

You'll Blind Somebody is a damage challenge

Challenge requirements
The Courier must deal 4096 points worth of damage with rifle grip energy weapons.

Effects
Grants 100 XP upon completion.

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.
