Hi there. Class items will only have stats if you Masterwork it (adds 2 to every stat), or if you put mods in that increase stats. There are +5 and +10 stat mods, but there are a couple of other mods that have a secondary function such as the Powerful Friends mod shown in your screenshot. When you fulfill the requirement for these mods' secondary effect, it adds +20 to a stat such as Mobility.
