Silver-Tongued Devil

Silver-Tongued Devil is an achievement earned by winning 50 Speech challenges.

Glitch/Exploit
The following may not work for all versions and all platforms.

Go to Big Town, speak to Bittercup, who usually is sleeping in the Common House. Talk to her until she mentions she dated Pappy. Speak to Pappy. The easy speech check "I heard you came here with Bittercup" dialogue option will never disappear, giving the player a chance to earn unlimited experience and an easy way to earn the achievement. This is no longer possible on the PS3 version as the Pappy exploit has been patched and removed.

Note: Works in the Xbox 360 version.

Note: Doesn't work in trophy patched Playstation 3 version of the game.

Tip's for Silver-Tongued Devil run
 These should work on all 3 versions of FALLOUT 3 

These tips are mainly for those people who have left Silver-Tongued Devil as their last Trophy, and those who have yet to start the game or havent done many quests.

For those starting new game to get this trophy I recommend getting as good speechcraft and charmisma so you dont have to load so much. So having decent charisma and tagged speech skill you should be able to win most of the speech challenges with ease.

Here are some Locations that help you to get the trophy.

Vault 101 Not many speech challenges here but be sure to save Amata before taking the G.O.A.T after escaping vault 101 be sure to get speech challenge from Silver who lives in small ranch between Vault 101 and Springvale school.

Megaton Plenty of NPC:s in Megaton that you can use your speech skill on. Heres the list. Lucas Simms, Jericho, Doc Church, Mr Burke, Gob, Colin Moriarty, Leo Stahl(you probably need to win Doc Church's speech challenge before you can do this) You can also lie to Moira brown multiple times during the wasteland survival guide quest. I also recommend getting the bloodties quest from Lucy west
