I'm always confused by this... the Security charms that increase with Class Specific armor. Is there a cap? and if so, how many does it take to cap it?
I think you can lose two pieces of expansion/class specific armor before you start seeing a decline in stats.
They used to go above 100%, so if you had a class only weapon or whatever it went up higher, the evolving items count as a class item, seems to barely go down with 7 or 6 now though.
