The when equipped effect on Stout Hammer of Fuga grants 60 to WIS, INT, AGI, and STR as well as 4% potency. The problem is that it only grants 10 to said stats, and 2.8% potency. I discovered this on my mystic who only has most advanced solo legendary and a few fabled pieces, nothing extravagent until I got this hammer. If anyone else notices this problem post here too. I also sent a bug report in game. Hopefully it will get fixed
this can be deleted, i'm stupid and missed looking at one item when i checked all my stuff... user error, move along
