Are forbidden keys only for use in the final mission areas? (I'm not up to it)
Are the stoneroot keys only for the Kurzick elite mission?
If not, where do you use them? :/
In the Kurzick repeatable challenge mission (Ruins of Altruum or something) what does refined amber do? I heard it counts for 2 as opposed to the standard one that drops from mobs but I dont recall seeing the score jump ever when I picked them up...
