The only reason to go for Int over +Spell Dam pre-40 is because there really isn't much gear with +Spell Dam on it until around 40. Even before 40 though, I'd take +Sta over +Int. After 40 it's +Spell Dam, +Shadow Dam, +Sta for me. Now alot of the peices with +Spell Dam and + Shadow Dam also have +Int, along with quite a few of my +Sta gear. However, I have never put a peice of gear on that had ONLY +Int and no Spell Dam or Sta, unless it was a long time ago, and I had no other gear in that spot. +Int is not really something to look for in gear IMO, you'll end up with plenty, but don;t go looking for it, +Spell Dam and +Sta are far superior.
