Figurine - Strength: Lucas Simms's house [Megaton]
Effects: Strength raised by 1 point.
Additional info: I wouldn't recommend trying to break into Simms's shack, because you might get caught. Instead try waiting for him to return to his home and follow him to that location. The figurine is located in his bedroom, on the first floor.
Figurine - Sneaking: Den [Yao guai tunnels]
Effects: Sneaking skill raised by 10 points.
Additional info: As the name of the location would suggest, you will be dealing with a lot of fierce creatures while trying to get to the figurine. Examine the central area of the den and eventually you'll find this object.
Figurine - Luck: Arlington House [Arlington cemetery]
Effects: Luck raised by 1 point.
Additional info: There are two zones for you to choose from when you want to fast travel - Arlington cemetery north and Arlington cemetery south. Either way, you must locate a building in the central area of the cemetery (screen). The figurine is in the basement.
Figurine - Unarmed: Rockopolis [Capitol wasteland]
Effects: Unarmed skill raised by 10 points.
Additional info: This is by far the most difficult figurine to find, mostly because Rockopolis isn't a primary location, so it won't be marked on your personal map. Look at the first screen for precise bearings. You must travel to Girdershade or Smith Casey's garage and begin your journey from there. You'll know that you've arrived at your destination when you meet a junkie. Approach a large rock near his location and press the action key to travel to Rockopolis.
Figurine - Endurance: Deathclaw sanctuary [Deathclaw sanctuary]
Effects: Endurance raised by 1 point.
Additional info: Obviously the entrance to the sanctuary is being guarded mostly by deathclaws, but you may also encounter Enclave soldiers and scientists.
Figurine - Agility: Office [Greener Pastures disposal site]
Effects: Agility raised by 1 point.
Additional info: Watch out for dangerous radiation and proceed to the office building without any hesitation. There are a few radroaches inside - kill them with a melee weapon.
