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. When you first talk with her, be nice and agree with her, telling her that no one understands you either, 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 haven't done many quests.

For those starting new game to get this trophy I recommend getting as good speech and charisma so you don't 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 and quests that help you to get the Trophy or Achievement.

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. Here is 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 Blood Ties quest from Lucy West

Blood Ties quest This quest is fairly quick and has plenty of speech challenges. After getting the quest from Lucy West you can get first speech challenge from Evan King. There are also plenty of speech challenges in Meresti Metro Station. For more information check the Blood Ties quest.

Tenpenny Tower quest This is a gold mine for those trying to get this achievement or trophy. Whole Tenpenny Tower has plenty of characters you can use your speech on. For more information about this quest, check the Tenpenny Tower quest section for more details.

Oasis quest has handful of speech challenges as well, but not nearly as much as Tenpenny Tower

Republic of Dave Has total of 3 speech challenges if you decide to do Election Day quest.

Rescue from Paradise quest Has few speech challenges if you: 1. try to buy your way in to the Paradise Falls on the front gate, 2. Win Eulogy Jones in speech challenge and you will get the children for 1200 bottle caps. 3. You convince the Kid in Little Lamplight to leave the cave and to be caught by Child Slaver note: you need to ask Eulogy Jones to get this quest.

If you still miss few after getting speech challenges from these quests try following quests.

- The Superhuman Gambit (having black widow or Lady killer perk may interrupt your chances on getting few challenges!) - The Nuka Cola Challenge (Note: you do not need to do the quest, just the first speech challenges.) - Tranquility Lane (go for the bad karma route)

Easiest way to get these speech challenges is to create a new character and maximize speech as fast as you can. Also it doesn't hurt to have high charisma as well. It will take few hours of work but a lot less than hacking 50 terminals.
