I ascended this because I have Etheric light to spare but I think its a good gun. How many time have you hear people say "this is a great gun but too bad its exotic cuz i dont wanna fill up my exotic slot (Gjallarhorn)" This is that gun. It has a unique perk that is not available on any other gun and it does not take up your exotic slot because its legendary. Dont get me wrong I havent used it once since I ascended it, but thats not what the post asked. Is it worth ascending? Absolutely IMO.
