How to use power roles:
Vig: shoot people who are going to get lynched anyway. Don’t shoot your scumreads unless you’re very sure. Shoot who town looks like they’re about to lynch
Doctor: protect PRs and TRs
Alignment cop: use cops on people you have no read on, who might also be useful to know the alignment of. so don’t use cops on people who are heavily SR’d. You’re looking for guilties on people who might coast for a long time
Rolecop: Instead of caring about your own reads like you would as an alignment cop, go for who you think is globally scumread. You’re essentially trying to keep ahead of the lynch train. If someone is getting lynched soon, you would expect them to claim as they get run up. Sometimes scum can claim something like town doctor or cop to at least flush out a counterclaim before you die. But you’re a rolecop. You’re fucking useless. So if the wagon starts getting pushed off, you can at the worst case come out with a counterclaim so that the real cop/dr can stay hidden. Ideally you don’t claim, and just try to influence the wagon.
Watcher/Trackers: You’re trying to get guilty results. You should watch people who are likely to be NK’d, you should track people who are likely to carry out NKs (scumreads, but usually the least suspected one of your scumreads). You’re trying to track people to dead people, and watch dead people get killed.
Item gifters: Give them to strong townreads who you don’t think are likely to die soon. If the scum strongman has been lynched, then give it to your strongest townread since that’s likely who the doctor will protect.
VTs: Provide cover for power roles. Ideally, all of the loudest and most townread people in the game should be VTs, and all of the PRs should be very middle of the road. Then scum has no idea who to kill.
