I know these posts are quite common in other Phasmophobia communities, but it feels like I finally beat the game. It only took about 10 hours of attempts across 2 nights.
The only things left for me to do are to prestige for the third time and then get insta-gibbed by a demon in less than a minute.
My only regret is dying at the last second on my Revenant attempt. Had the whole book filled out, and it would have been so cool to have a rev win! But alas, the deogen is tried and true. Rerolling for favorable objectives and a deo is the way to go.
