I know that standard mace/pepper spray will ‘fill up’ an area when fired indoors, affecting others that are within close proximity. Bear spray is a lot more powerful, stable stream but I wonder if it would still do that.
I’m imagining you spraying an NPC in the face inside a shelter and having the ‘cloud’ hanging in the air the way smoke does for a period of time, blinding and irritating everyone within a tile or three.
Because when I hear bear mace I think ‘Spraying humans in the face’.
Plus it rhymes.
