This bug is limited to the char screen (cause testing real crit chance in game is more work I'm willing to do
When my archer is using bow+arrows and I equip the Steam Powered Gauntlets (Physical Crit Chance +10%) I get LESS crit chance on my weapon than on the generic "Physical" section. If I'm using say a dagger, I get the same crit chance on both.
The difference is due to the fact that somehow, the Steam Powered Gauntlets give not 10% but 20% physical crit chance. Except for ranged weapons it seems where it gives the normal +10%
