Fallout New Vegas: Cassidy Quest and getting 3 Perks for her :)

This trick is rather hard to pull off
However if done right:
Cass will get Bonus HP +50
Bonus damage or firerate with shotguns
Shotgun Surgeon Perk
Raw material for this vid had 50 minutes and game audio keep having issues...
new vegas keep being broken as always, even if i manage to work around problems
Editing goal would be go under 35 minutes long video just by cutting barter windows
and maybe looting and loading times alone, i also cut some strols with nothing in it
fast travel in video is used exclusively to save the time and showcase the thing in
reasonable timeframe to make watchable video out of it
Step by Step instruction:
1. do the visits to caravans
2. get the evidences
3. destroy van graffs
4. bring evidences to NCR
5. kill Alice Mclaffy
DONE
2 perks gained
HP 275 go to 325
Damage perk gained
