Yeah this is something I do not understand...in the encounter that has the least benefit(12 nukas or 24 with high lockpick), why is there a 203 hp centaur guarding it?!
All the others simply have places to search...the clinic, which just has some medical stuff and needler pistols, requires high lockpick. Vertibird and bunker don't require anything, correct me if I am mistaken about that?
