As I make my way through Act I, I have gathered quite a few weapons and armor that have skill requirements way beyond my current levels (most of which from behind the armory counter using the summoning doll trick). I don't know whether hi-level weapons & armor will be readily available in later acts or should I make it a priority to carry these heavy pieces with me to the next act and keep them in the battlefields? My BF storage barrel is getting absolutely packed with these things. Should I sell? Should I hoard?
Also, I am also getting some amulets, belts, sashes, and so on. Most don't vary too much in armor levels, only in their durability levels, but I never notice their durability going down. What's the deal with them? Should I just keep one belt and one amulet? What makes these items take damage? For that matter, what makes one item take more damage than another? Is it just random? Do certain enemies target one item over another?
Incidentally, I do have armor durability +1 on my character.
