I don't know what it is. I probably won't use it much over gjallarhorn and other things. I want that gun though bad. Maybe it's just cause I don't have it. I don't know. But I can't get it. Same with heart of the praxic Fire and helm of saint 14. I've spent ludicrous amounts of motes on engrams from xûr. No praxic no saint 14. Not sure if I can complain about my RNG luck with exotics though all things considered.
