While I was crafting my quantum helmet today I noticed that reinforced glass is part of it. I guess it is supposed to cover the face or the eyes as some kind of shield.
And since this is high end quantum stuff with advanced circuits and all of this I thaught this helm needed a HUD .
Of cause I dont know if that is even possible for a forge based mod but my suggestion is, as soon as you equip the helmet you get additional infos on your screen like in a Jet or in Iron Man. For instance speed or position markers and livebars for mosters, so you get this "locked on to target " fealing.
