Do Skill Mags work like in Fallout 3 so if you use it the effects are permanent? I hope so because I think last time I played NV it was temporary, and if so, how long does it last?

Skillbooks are permanent, but they are rarer.
Edit: Usually a +1 increase as in Fallout 3.

Skill mags are temperory and work like the various stims (except no addicition) They are more plentiful and good for when you need a quick boost.
Edit: Mags tend to give a +10 increase. So short term they're more useful.

Thanks! Didn't even realise there were 2 types of skill modifiers...Cheers! :celebration:
