First: The Potshot

It's night one. Nobody stands out. Nobody has made any hints at roles. What do you do? You take a shot in the dark. You pick an account with average levels of activity, because the louder a person is, the more chances they have to get themselves lynched. So you pick off one of the fringe dwellers, and nobody can pin it on anyone.

Second: The Incriminator

Player X has been gunning for Player Y pretty hard. They're both townies, because you're the dirty scum sucker. You shoot Player X, and suddenly, Player Y is looking pretty smurfing suspicious. Has the added benefit of potentially forcing a townsperson lynch. Double kill.

Third: Power Limiter

You spot someone talking about the Doctor, or the Cop. You shoot them. People who discuss roles like that are either scum or hinting at being it. If not, who cares? Townie still dies.

That concludes our first lesson.
