Starlight is your guide. No vacuum will contain you.
The Celestial Nighthawk Hunter helmet is designed for a mainly PVE oriented Gunslinger. It has little to no utility in the Crucible. This exotic changes how your Golden Gun operates, with the exotic perk, Big Game which substitutes your three Golden Gun shots for just a single shot. This helmet also grants the Gunslinger perk, Keyhole which allows your shot to over-penetrate and damage multiple targets. The Celestial Nighthawk, is ideal for a Guardian who participates in a lot of high level PVE activities such as Strikes. It allows you to dole out 6x damage to the Ultra level boss in one fell swoop which can allow you to get straight back into the fighting.
This exotic helmet has a design that certainly lives up to its name. The short beaked design of the Hawk emphasises the provision and great use of the accuracy of your Golden Gun. The colour scheme of the helmet shows how well used it has been in the battle against the Darkness. The main segment that is a dirty golden colour contrasts greatly with the white on the side and makes the helmet pop no matter what shader you are using. The darkened eye holes of the helmet are quite understandably in the shape of the eyes of a bird of prey and present an air of hostility that make every adversary feel small and insignificant like a mouse under the Hawks gaze.
How to Acquire it?
