Ok so i took it and havent had anything wierd or wild happen yet, what exactly happens when having it ?

ive been wondering the same thing

one thing go to my last post about it or go to vault wiki.

it basically creates random encounter with stuff, usually easter egg-ish. you know you have used the trait when you encounter something because a little eerie tune plays. an example of the trait working is near the beginning you find a man in a fridge dead. this man is indiana jones and you can take his hat. when you see him, a strange song plays. without this trait you never would have found him because it never would have been there. i dont want to give away other examples, but there are quite a few more and while you might not get something, it definitely is cool

Nice same with the alien blaster and the gauss rifle
