What stat gear should I expect at higher levels? And more importantly, should I adapt my character to odd or even gear? I've heard that stat gear maxes out at +3, but that doesn't necessarily mean there's +3 gear for every stat. And maybe some of the +3 stuff occupies the same gear slot...
I'm clueless
In a more specific case, should I end with 23 Cha and 15 Con on my warlock? Or rather 22 Cha and 16 Con? Or would a mix of both (one odd stat, one even) be better?
