Charisma Bobblehead (Fallout 4)

The Charisma bobblehead is a miscellaneous item, a Vault-Tec bobblehead. In Fallout 4, it permanently improves the Sole Survivor's Charisma by 1, up to a maximum of 11. However, if the player wants to reach 11 points, they should not take the bobblehead before having improved their Charisma to steady 10 points.
