Im not exactly sure what weapon you are talking about. But if you have beaten all the temples then you probably don't need whatever weapon it is you are missing. However you need to get all the masks. You can't beat the game, and you will see why, without all of them. The cow mask is gotten after you help the ranch on the first night by killing all the aliens. The next morning talk to Malon's guardian (haha sorry I can't remember her name) and she will ask if you want a ride into town tonight at 5. Say you will go with her and make sure you are back at the ranch when she is ready to go. You will have to keep away some men you try to steal milk from the cart while you are riding but it is simple all you have to do is shoot them with your arrows. When you reach the town she will thank you and give you the cow mask. The couples mask is a very detailed walkthrough which you can find anywhere on this site. Good luck!
