Never been pepper sprayed, but i have been in a tear gas chamber. It ought to do both the effects you listed. Maybe give them both the same stats, but Peper Spray is against one person, and Tear Gas is area effect. IRL Tazers can incapacitate any living human, but like you said, no precedent for that in game stats.<br/><br/>Although realistically, Mari is kind of screwed if she uses it. It burns exposed skin too, not as much as the eyes and mucus membranes, but still irritating. It might not be a whole success worth of penalty, but she'll want to take a shower after using it.
