So first of all, hill seems to work for me, it deals damage to an enemy 3 or 4 tiles away so it effectively hits without getting hit. Secondly, as far as I can tell the key to making good stuff is to give base +scaling for a single stat corresponding to what you have on the character you want to use it for and then increase the positive %scaling on that stat as well; otherwise it doesn't matter if you gave it huge damage scaling or great +scaling, the positive and negative scaling are equal so it's all rng if it's even usable. I also noticed a decent amount of items with incorrect effects shown compared to what they did in the crafting screen so be careful with that.
