Alchemist's gas mask

This Unique Gas Mask was made by a master Alchemist named Uranidus, for the purpose of entering hazardous areas to collect poisonous spores or other dangerous materials. 

While wearing the Gas mask, you gain immunity to all airborne toxins, spores and attacks that utilise airborne toxins or spores (e.g. cloud kill)

While wearing this mask you have advantage against any save that is caused by a gas (e.g. a wisdom save to not be charmed by an alluring perfume)

While wearing this mask you gain disadvantage on ranged attack rolls due to your vision being slightly impaired, due to the masks experimental nature.
