Two bugs: some drops to not appear, "Argenta's breath" hidden abilities
1- Sometimes some items do not appear after drop. You have to leave the area few meters then come back, they will appear on your screen. So watch out, you might miss some important items.
2- The "Argenta's breath" is a blue necklace but I cannot use the accessory hidden ability on it.
Untradable items are unable to be sparked.
ALL quest rewards are unsparkable which I understand, I just wish you could sell them its ridiculous you need to destroy them.
