Rating Difficulty: Normal

Do 15 out of 17, with the help of The Encroaching Darkness divination card. This challenge will be slightly easier to complete as you keep grinding end game maps, collecting these cards and naturally dropping unique maps. Even if your RNG is not in your favour for collecting these cards, you could easily buy most of the unique maps here, as most of the unique maps are quite cheap. Also look out for people sharing unique map completion on Global 820 and 4040.

My least 3 favorite unique maps and ones I would skip are ... Doryani's Machinarium(expensive), and The Vinktar Square(slightly expensive). The rest are relatively cheap and common enough to compete for cheap, and maybe even make a profit doing so!
