My DM once fudged something and I didn’t question it at all. It was in curse of Strahd, the party was level 3. He was using the RAW rules in the adventure for random encounters, one of which says the party can get jumped by 3d6 wolves. He rightly surmised that us getting ganked 10 wolves wasn’t a very interesting conclusion to our story, so he made up some dumb deus ex machina, and I was 100% there for it. If WOTC can’t make a balanced random encounter table, why should we be beholden to it?
