Sometimes making a stat-perfect build can be a little tedious because you have to buy certain uniques before you can buy other ones (because you need the str bonus to equip the next).
So my suggestion is to possibly make some way to buy items higher than your current stats. Not all of them, maybe just things that are.. 10% higher than your current stats. Just an example number, anything small amount would be awesome.
Maybe I just want an easy way out, but it's just a shame to see something like a Vampire Gaze or Demonic Circlet in the showroom, but you need a few more strength from another piece of equipment to even buy them.
