Mama Murphy

Mama Murphy is a chem-addicted fortune teller, traveling with Preston Garvey and his group of settlers in the Commonwealth in 2287.

Background
"Mama" Murphy is an elderly seer that specializes in the "Sight," a supernatural power that she claims is sourced from chems. She takes the drugs in order to utilize her powers as a psyker to predict the future. Hailing from Quincy, she left the town with Preston Garvey and the 20 remaining settlers when it was assaulted by mercenaries. She and the refugees were holed up in the Museum of Freedom when they were ambushed by raiders as they passed through Concord, and she can be found with the last of the survivors on the upper floor of the museum.

According to her, she was once a strong and ruthless fighter, very muscular and specialized in unarmed combat. She claims that she once ripped the head off of a raider using just her bare hands, earning her the nickname "Murphy the Madwoman."

Mama Murphy uses chems to induce a trance-like state in which she claims to see "things that were, things that will be, and even some things that are, right now." She uses her power out of a desire to protect the people she cares for, providing warnings of danger and advice on which courses of action to take.

Quests

 * Jewel of the Commonwealth: After helping her group to escape Concord during the quest When Freedom Calls, Mama Murphy will suggest the player characters goes to Diamond City to find more information about Shaun.
 * The Sight: In exchange for drugs, Mama Murphy will use her gift to reveal some parts of the Sole Survivor's future.

Other interactions

 * During When Freedom Calls, if talked to she will be the one to reveal Dogmeat's name.
 * After passing a speech check during When Freedom Calls, she will foresee a deathclaw attack. Upon completion of the quest, she may comment on how back in her youth, she killed a deathclaw with a single shot without any "fancy power armor or minigun."
 * Upon completing When Freedom Calls, Mama Murphy commends the Sole Survivor's success and reports the player character's son is alive somewhere in the Commonwealth.
 * After the main quest is completed, Mama Murphy can be given chems to provide insight into the ending the player chose, provided she hasn't been convinced to give up chems.
 * If you persuade (not confirmed with threatening her) her to quit chems Mama Murphy will say this if the Sole Survivor is close "Mama Murphy is as good as her word kid. No more chems, and no more Sight either."

Appearances
Mama Murphy appears only in Fallout 4.

Mama Murphy can be obtained as a vault dweller in the mobile game Fallout Shelter.

Bugs

 * If one does not craft Mama Murphy's chair properly, she will be stuck sitting in the chair in the ceiling of the house in Sanctuary that has the main workbench attached. She will be above the kitchen with (usually) only her feet showing. One must shoot her feet until she falls out of the chair, then go into "edit" mode and bring the chair out of the ceiling and on the floor. She will then spawn back in normally and sit in her chair as normal. If the player fails to shoot her feet, they will need to find a way to press the action button to talk to her and convince her off drugs.
 * She may become non-assignable, like Sturges. On PC, a similar fix to solve the problem with Sturges can be used on her: Use the console command on her, fast travel far away, and after a while go back to Sanctuary. The "Command" option should be available on her after that in Workshop Mode.
 * She might refuse to get in her chair just standing next to it. When the player tries to speak to her she will tell the player that she needs to sit down, no other interactions can be made with her. There are two possible ways to fix this:
 * Scrapping and rebuilding the chair may fix this bug. Once scrapped, the chair will become available to rebuild after waiting or sleeping for an hour.
 * By opening the console, selecting Murphy and typing.
 * Sometimes the vision the player character gets from her is not about the current quest, but refers to some older one. For example, during Hunter/Hunted, she might give them a clue to get the key for Kellogg's Diamond City house which corresponds to the already finished Reunions.
