Your spine has been replaced with advanced technologies: Your torso can no longer be crippled and your Strength (STR) and Damage Threshold (DT) have been increased (+1)”— In-game description
In the initial dialogue with Doctor Klein as part of the quest Welcome to the Big Empty, the Courier finds out that his/her 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.
- This perk is replaced with Reinforced Spine if the Courier chooses to put his/her spine back by the Sink Auto-Doc during or after the end of the add-on.
- Compared to Reinforced Spine, this perk grants half the Strength and Damage Threshold bonuses with the benefit of making the torso incapable of being crippled.
- The +1 to Strength is not added to base Strength, so it will not count toward qualifying for perks when leveling but will count for all other strength effects.
- This perk synergizes poorly with Eye for Eye, as it reduces the total number of limbs that can be crippled.
- This perk's Vault Boy image is the same as Reinforced Spine's.
