From publisher blurb: It happens with every experienced gaming group. As Game Master, you can’t put your players up against a creature of appropriate CR without hearing them accurately estimating its AC, hp, and special defenses. Throw a high CR monster at them and you might be serving them XP on a silver platter or guaranteeing a Total Party Kill. It isn’t your fault. It isn’t your players’ fault either. Invariably a group that plays together a long time learns the game better. You can accept this and watch your encounters get decimated. You can move on to a different game, kissing your shelf of gaming books and the money you invested in them goodbye for now. Or, you can break out the secret weapons.
