Make nukies helmet/mask acid smoke immune?

i'm all for student's effective dose reduction - irreplaceable helmets should probably just reduce the effectiveness of acid rather than be deleted.

IIRC it's actually the mask actually performs the full on protection? Helmets reducing the volume could mean there's a greater threshold for fluoro chemsmokes melting the mask.

I personally like the idea of acid resistance for these things degrading, too. so maybe the first application is completely blocked, but as acid is used more the helmet lets more and more through (so acid beakers remain a viable melee weapon)
