I agree with the previous posters about the importance of the stats.
If ever I am given a choice of which stat to raise, I choose INT. The reasoning for that is that INT is much harder to raise than our other stats, without sacrificing too much.
Most items with INT have STA/WIS to go with it. It is rare to find an INT item with AGI/STR on it. If I do see one, I jump on it. Due to the fact I don't like WIS/STA much, my INT has been quite neglected
STR is better than INT, but I suggest choosing INT when you can, as you will get a decent STR without trying too hard.
