  • If the player has an Endurance of 8 while having no stats at 1 or a Luck of 10/1, Doc Mitchell will say "I guess that explains how you're still alive. You're built solid as an oak."
  • If the player has an Endurance of 1, Doc Mitchell will say "I just don't get it. A stiff breeze'd tear you in two but a couple of bullets and you're right as rain."
  • A starting Endurance of 9 will guarantee you the ability to get every implant. An Endurance of 7 will allow you to get all SPECIAL increasing implants.

Fallout 4

Endurance is a measure of your overall physical fitness. It affects your total Health and the Action Point drain from sprinting.

Fallout 4 loading screen hints

Endurance determines your starting Hit Points, as well as your additional hit points per level. Additional points in Endurance are retroactive; increasing it later on in the game will reward all the hit points the player would have gained with a higher starting statistic.

Additionally, Endurance reduces the rate at which Action Points deplete while sprinting or, (with the Strong Back perk) running while over-encumbered.
