Bobblehead - Endurance
"Always be ready to take one for the team."
Found inside the Deathclaw Sanctuary. To find it, go directly south from the entrance, and then go down the rock ramp. It is located on a small pedestal next to a brahmin corpse to the left. A mini nuke and a copy of Nikola Tesla and You are on the same platform. More over you can find a Nuka-Cola Quantum on the other side of the rotting brahmin.
