Spineless

Spineless is a perk in the Fallout: New Vegas add-on Old World Blues.

Obtaining
In the initial dialogue with Doctor Klein as part of the quest Welcome to the Big Empty, the Courier finds out that their brain, heart, and spine have been removed and replaced with advanced technologies. This perk represents the replacement of the Courier's spine. While the Courier is technically spineless from the start of the add-on, this perk is unlocked in the course of the conversation, along with Heartless and Brainless.

Effects
The Courier's Strength and Damage Threshold are raised by 1 point. Additionally, the Courier's torso cannot be crippled.
