In the 1.5 update, one of Stardew Valley's most mysterious figures makes another appearance. After unlocking the Walnut Room on Ginger Island, players once again meet Mr. Qi — and big surprise, he has more challenges to test their greatness. Once the player completes one of Mr. Qi's new "Qi Challenges," he will reward them with Qi Gems that they can redeem for highly useful items. All of these quests can be repeated for an indefinite number of Qi Gems. Some of these tasks are fairly simple, while others are nigh impossible.
