So, I'm up to the final confrontation with the Master in the first Fallout game, and well, I like to talk my way out of things. I've done everything to prepare to convince the Master to blow himself up, but the dialogue options aren't appearing for me. I have Vree's Autopsy Disc, I've even uploaded it to my Pip-Boy, but when the time comes in the conversation ("I've found a problem with your plan.") The option to tell him that his Mutants are sterile does not appear. By the way my base intelligence is 8 while I boost it with Mentats for 10, so I don't think that's it. Is it my Charisma at only 7 or is there a glitch of sorts? What is wrong here?

According to Per's walkthrough you'll need:



Therefore I think you have inadequate speech skills. Although Per doesn't mention how much speech is needed in this quote. I believe it is 75+ but I forgot the exact amount.

Charisma doesn't matter here, only intelligence and speech. You need at least an intelligence of 7 (which you have), and a fairly high speech skill. I finished a game of Fallout this past week and convinced the Master that his plan was doomed with my speech skill at 151%. What's your speech skill at exactly?

My Speech is exactly 100%...

I'm not sure what the problem could possibly be then. Did you actually at least skim through the report after downloading it to your PipBoy?

I figured it out earlier today. I didn't read the whole report. I just opened it and had a conversation about it with the Vree. Now the Master is dead and I finished the game. Now on to Fallout 2.

Congrats.... Its not an easy ending to get.
