Played through a full run as the Tempter and had a good time. Writing is the best part. It's grim but funny too, and Mahariel cracked me up. I really liked that you pick how you corrupt each race instead of just raising a number. My dwarf cult turned into a secret science guild that worshipped me, which I loved.
It's really replayable, and I'm definitely going to try another class. Nice work!
