Guide
This achievement is optional, as are all of them, and tends to be much more difficult than the other achievements. The main part that is hard about this is that you must face the Nasty Owl, and without power-ups, this can be quite the challenge. It is highly recommended to do this on normal difficulty, as in doing so you increase your chances of surviving. Not always, but usually, completing this achievement will reward you with They're no good in your pocket. It's recommended to get cards before attempting this, such as Lucky Shield, Health Regeneration, and any other cards you can get. All regular tactics against the boss apply, except that you can't use your power-ups.
