Retribution
This is a problematic power on a unique class. It makes it impossible to get away with a claim, since even lynching an Innocent Hunter ensures the death of an evil.
There’s no good excuse to avoid getting lynched, and makes it harmful to your team to try to ensure your longevity during the day. I’d remove this entirely.
Frame/Mindwarp
There is no counter play to this power. You have no hint that your results were wrong, they just get screwed up. While it is a strong ability, it is rare and will just come out of no where and screw you over. It’s just a pure bastard mechanic, since it rarely succeeds.
If you want to make investigatives untrustworthy, the real answer is somehow tilting the odds in favor of the Scorned. It is the perfect way to make people suspicious of investigators, and you can try to read the person instead of having no way to determine if they are correct.
I’d replace these abilities with some other ones.
