Have you got the books? Books (not magazines) boost those skills permanently without needing to level up (even better if you took the Retention perk or whichever it is that doubles the boost or whatever)
Yeah, I get +20 from magazines (instead of +10).
Probably I found a Repair book at some point as well; don't remember.
But they're pretty rare! Unless you will player.additem - which I will not do...
Gonna take a whole library to buff that repair skill through the roof!
But then, I'm not playing hardcoe even though it would make things a lot more like S.T.A.L.K.E.R. (which I love).
Point is, the jury-rigger would probably be more important in hardcoe...?
