Since my previous topic resulted in very undetailed results, I decided to post a focused and specific topic instead.

So, since Dead Money is the first DLC released, what skills do I need when I go there?

So far, I've found out that there are 100 lockers.

Science? Medicine? Sneak? Explosives? Guns? Energy? Unarmed? Melee? Survival? Speech? Barter? Repair?

P.S. Yes, I am interested even in redundant things, if it requires X skill level, I wanna come in ready, even if it's an empty locked locker.
