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

Tips for Silver-Tongued Devil
Note: The following tips will work on all three versions of fallout (XBOX 360, Sony PS3, and PC):

These tips are mainly for those people who have left Silver-Tongued Devil as their last trophy/achievement, and those who have yet to start the game or haven't done many quests.

For those just starting the game, it is recommended that the player put points into Speech and Charisma to speed the process. Keep in mind that much of the work on getting Silver Tongued Devil will be finished if the game is played thoroughly, and in fact, along with other trophies/achievements of this type, will likely be complete if the player opts to play all of the side quests and to explore the world outside of the main storyline.

However, if necessary, the following quests and/or locations present speech challenges that will aid in gaining the trophy/achievement:

Vault 101
There are not many speech challenges in the vault, but be sure to save Amata before taking the G.O.A.T. After escaping Vault 101, be sure to get the speech challenge from Silver who lives in small ranch between the Vault and and Springvale School. Even if you're not really interested in the money she gives you, you could always execute her afterwards.

Megaton
There are several NPC's in Megaton that present speech challenges: Lucas Simms, Jericho, Doc Church, Mr Burke, Gob, Colin Moriarty, Leo Stahl (the player will need to win Doc Church's speech challenge before they can do this one). It is possible to lie to Moira Brown multiple times during The Wasteland Survival Guide quest, though much less loot and perhaps a lost perk will be the result if too many lies are told. The player should also take care not to talk Moira out of finishing the guide.

Blood Ties Quest
This quest is fairly quick and has plenty of speech challenges. After getting the quest from Lucy West the player can get a speech challenge from Evan King in Arefu. There are also several speech challenges in Meresti Metro Station.

Tenpenny Tower Quest
This is a gold mine for those trying to get this trophy/achievement. Tenpenny Tower has many NPC's offering speech challenges. No matter your choice (to help or kill the ghouls) you can get a speech challenge from Gustavo, as well as the five people on Tenpenny's list.

Rivet City
There are 4 speech challenges involving a rumour mill with Vera Weatherly. There are also a handful of them to do with The Replicated Man quest. There is one with Dr. Madison Li which will get you 5 stimpacks once you talk to here about Dad. There is one with Abraham Washington concerning the Stealing Independence quest.

Oasis Quest
There are a handful of speech challenges when doing the Oasis quest.

Republic of Dave
There are three speech challenges when doing the Election Day quest.

Paradise Falls
The Rescue from Paradise quest has few speech challenges:
 * 1) Try to buy your way into Paradise Falls at the front gate;
 * 2) Persuade Eulogy Jones to sell the children to you for fewer bottle caps;

Little Lamplight
Convince Bumble in Little Lamplight to leave the cave and go with the Child Slaver Note: You will need to have spoken Eulogy Jones before going to Little Lamplight to get this quest.

Canterbury Commons
The Superhuman Gambit Note: Using Black Widow or Lady Killer may prevent the player from accessing a some of the challenges on this quest.

Girdershade
The Nuka Cola Challenge The player does not need to complete this quest to get all of the speech challenges.

Jefferson Memorial
Take it Back!, the last quest of the game, offers two speech challenges when you meet Colonel Autumn for the final showdown at the end.

Underworld
You Gotta Shoot 'Em in the Head has many speech checks for players wanting less violent ways to accomplish the quest. All told this quest has 19 possible speech checks, the largest of any other single quest.

Vault 112
Complete the Tranquility Lane Quest with the bad karma options to unlock several speech checks.

See the Speech article for a full list.

Glitches
There are two glitches available which make the accomplishment of this achievement incredibly easy.

First Option (Unpatched version only)
Go to Big Town and speak to Bittercup, who is usually sleeping in the Common House. When you first speak with her, be agreeable and tell her that no one understands you either. Eventually, Bittercup mentions that she dated Pappy. Then 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, nor does it work on the latest patched XBOX 360 version.

Second Option:
First, travel to Little Lamplight (see link for exact location). There is a young girl in the city named Knock Knock, sister of Knick Knack (owner of the souvenir shop), who can mostly be found in the Great Chamber or at the Fungus Pool.

Talk to her, and she will try to tell a joke. Play along, and after hearing it out she will ask the player if it was good. If the player succeeds in lying to her, she has won a speech challenge. Ending the conversation allows the player to repeat it an unlimited number of times. Still works on patched XBOX 360 and PS3 versions. On the PS3 version however, you may have to shoot your gun afterwards for the trophy to come up (I know it sounds daft but thats what I had to do). - tested on ps3 on 15 feb 2009 still works - also tested on PC 16 feb 2009
