To add to that:
- "special encounters" are not affected by any perks in FOnline, that's only in F2.
- you get -25 Rep per shot on a NPC faction in a random encounter.
- caravan quest aren't implement ["yet" I hope], so no.
- "Tag!" perk in F2 can be gotten at level 12, but for some reason, it isn't in FOnline, I don't know why.
