Boone's Quest [Spoilers?]

[Yiffy Juicefox]

So after all my time in New Vegas I've never actually done his quest (not the one where you get him as a companion), but I know he has "history points" you get by doing certain things, and I know freeing the powder gangers in "Booted" gets you a couple points, problem is I did that quest before I met Boone.

So do I have those points already or are those just gone for good?

[Waldo]

TLDR those points are gone for good but there are many more points you can get

If all of the following have been completed before recruiting Boone, it will be impossible to accumulate the required history points.

Talking to Bitter Root at Camp McCarran about his history

Killing Vulpes Inculta: +1

Vulpes appears at multiple points, leaving several opportunities to kill him. He first appears in Nipton. If spared, he'll appear on the Strip to give you the Mark of Caesar (If you kill Vulpes when he approaches you at the strip, Securitron guards will not become hostile, nor will anyone else, making this the easiest time to kill him). Finally, he'll appear at the Fort by Caesar's side.

Eradicate the Legion: +2
While the eradication can be done at any time, for it to count towards Boone's history points it has to be done while doing Eye for an Eye and the current displayed objective is "Kill all Legionaries in Cottonwood Cove." Killing Aurelius of Phoenix repeatedly using the console is a viable option for farming all 5 trust points on PC.

Camp McCarran

When interrogating the captured Legion POW Silus, if he dies: +1.
Note that this history point is earned for Silus's death at any point, not just during torture. The ideal way of earning it is by making the Speech checks to have Silus discuss the information leaks, talking to Boyd to get the rewards, then re-entering the interrogation room with a weapon and killing Silus with a sneak attack. However, with the latest game update installed, after leaving and speaking to Boyd, the door will lock, requiring a non-existent key. This can be resolved by leaving a C-4 under Silus (if you have high enough Sneak and are able to keep holdout weapons), after submitting the quest to Lt. Boyd you can detonate the C-4 and kill Silus.

During the mission I Put a Spell on You, confront and kill the spy in act: +1.

Disarm the monorail bomb: +1 (no additional point awarded for this after patch 1.4.0.525. See Bugs)

The Fort

Killing Caesar: +2.

Legion raid camp

During the side quest Booted, rescuing the hostage Powder Gangers: +2

Nelson

During the side quest Back in Your Own Backyard

Kill the hostages: +1.

Save them: +2.
