I haven't liked hit area effect weapons because they seem to agro more monsters on me which is not a desirable effect for me anyway but recently, since I had 100 or so raptor teeth, decided to try some out I thought I would put 2 or three on a bow but it only allowed one and removed the other one. Still don't like hit area effects LOL. Just wondering what other properties might be similar in if you try to add similar properties the original is removed?
