Note : The following tips will work on all three versions of fallout ( Xbox 360 , 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 . If necessary , however , 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 . Then tell Butch to run away from his mother ( since it has a higher chance ) . After escaping Vault 101 , be sure to get the speech challenge from Silver who lives in small ranch between the Vault 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 non - player characters in Megaton that present speech challenges : Lucas Simms , Jericho , Doc Church , Mister Burke , Gob , Colin Moriarty , Leo Stahl ( the player will need to win Doc Church ' s speech challenge before they can do this one ) .
