I just was playing coven all any and, there is a glitch with poisoner I just found out.
If you poison someone and it reads in chat they have defense, they are in fact mafia. Not only GF, it showed Forger, and Mafioso as having defense.
I played a game as solo poisoner that I claimed Sheriff in and I went 4/4 on outing mafia. Basically handing town the win on a silver platter.
If there is a way to see match history I would love to check it out since my shadowplay was off.
Try it, idk why but poisoner is a TI and a TK.
