Good News About The 24 Stat Helms And Others

sry if its wrong for me to bump up this topic but i have a few more questions,

So all the Andras/other dude's equips are quest rewards? that means you can only get 1x set per character?

I heard the hat is karma'albe, are the shoes/gloves karma'able aswell?

Can i see the quest data of the quest that actually gives each of the 3 equip rewards?
