Endurance Implant

 is a Fallout: New Vegas perk.

Effects
Increases your Endurance by 1.

Increasing your Endurance with the Endurance Implant does not allow you to receive an additional implant. The ammount of implants you are allowed to buy will always depend on your original Endurance number when you created your characters SPECIAL. So if you created a character with 5 Endurance then you are only allowed 5 implants. However, increasing your Endurance with Intense Training does allow you to buy an additional implant.

Behind the Scenes
Called the Nociception Regulator, which refers to the actions of the Nociceptors, nerves that detect chemical, mechanical, and thermal damage to the body.
