Hollow man mask is available now and worth picking up if you don't already have it. 50% hazard protection from perfectly insulated and 10% built in as its Yaahl brand. All you have to do is roll 40% hazard protection on it and that will give you the full 100% on 1 item for your build.
Definitely worth getting this I think as I've just watched S.O.T.G. and it seems that in episode 3 some of the enemies will be ' cleaners ' which of course means lots of fire.
Anyway just a quick heads up to anyone who needs this item and to new players who may not be aware of it's existence.
