Another one of my possibly-stupid-possibly-not-stupid questions :

What does "send to wares" do ?

All I could see is that it puts items in a special item class : wares. Which might be marginally useful, if you want to flag all the items you intend to sell the next time you meet a merchant. Because then, when you are trading, you can go to the "ware" section and have them all gathered.

Any other use ?

Flash info : The Dark Urge is not an Origin Character. And it's not a new concept.
