I think this is an error calculating stats. I’m wearing a magic chest armor, lvl 14, with 140 of power and 368 armor stat. It just have +3 max. life as magic stat. I found another exactly same magic chest armor but with 380 armor stat instead (with +3 to max life too and lvl 14 and 145 of power), but in the resume it says that this new one has a -0.5% of hardness, when it supposes it should be +0.5% more.
Is it a mistake of mine?
