Joker Card

Complete all areas with a Jester cat to unlock the Joker Card, a trinket item. This achievement requires clearing every area in the game using the Jester class. The Jester's random spell casting through Smart Metronome and RNG Cannon means every encounter plays out differently, making this a wildly unpredictable grind. High rolls can trivialize areas, while bad luck can make simple encounters deadly. The Jester draws abilities from all other classes and gets an extra reroll on level-ups, helping build stronger stats over time. Put the Jester collar on cats with the best base stats from breeding so raw power compensates for the inherent randomness. This is arguably the most entertaining achievement to pursue, as no two runs feel the same.
