Ah yes... it is best to look on walkthroughs and see what items you can make and make them, ASAP, if you won't replace them. I have about 3 luck myself, an Emerald Chestguard + Golden Crystal Enhance, Creator's Belt + golden Crystal enhance, Agent Cloak + golden crystal enhance, and blessed necklace, which really helps keep just about all my resistances at 75+... armor is 114%. Experiment with gem enhancement on artifacts you make and will use forever. PReplanning is the way to go IMHO.
By the way, have you tried using strong daze when surrounded by enemies? It really makes the game much, much easier- and it's one of those really nice things that come along BEFORE you really need them, so you can actually appreciate it. (Darn lateness of the best creations...) Mass Madness might work too.
