Once a weapon has been changed. If that weapon is sold will it maintain the change or does it clear the slots, and can the augmentations be changed once the slots are full. I don't have the new expansion yet was just wondering. Seems to boost individuality in the characters to me.
All of the augmentations will make the item you put it on NO DROP, just like putting a NO DROP item into a tradeable container. The container then becomes NO DROP. Therefore, you cannot sell or trade any augmented item.
