Official Description: The Knutt Knight lives inside Baspinar's Castle and wants you to battle. Just like King Baspinar, he wants Marada to have a strong army trained and prepared for war. Accept one of his battle quests and he'll ask you to add a certain Trading Card to your battle deck, battle the opponent in the Arena and if you win, you have completed his battle quest. He will reward those who manage to complete his battle quests with BP and Diamonds, for use in the Elite Gym at Lush Lake.
More information: The Knutt Knight quest is the only quest that has certain timing limitations: due to Baspinar's Castle experiencing night time every other hour (in real life time), the Knutt Knight will fall asleep. The Knutt Knight will keep asking you to battle enemies as long as you keep visiting, but most people have found that some of the Trading Cards he could ask you to battle against were either inaccessible or just too expensive to finish the quest sometimes. To help those who have never attempted to battle, there are 12 easy to defeat Trading Cards now restocking. When starting out, you will be asked for the weakest and cheapest Trading Cards, with the quests then getting progressively harder at the 100th quest that you complete. As of 25th October 2017, both Knutt Knight and Sumo Sally will ask for retired and unbuyable Trading Cards a lot less often. These changes should help those struggling with battling, certain goals and should increase the supply of Diamonds.
Weather: The blackout has Baspinar's Castle and Eleka's Castle in darkness 24 hours a day. Therefore, the Knutt Knight will stay sleeping, and his quests cannot be completed.
The Knutt Knight is also an opponent in the Battle Arena; sometimes, upon completing enough of his quest, he may reward you with his Trading Card. Once you collect his Trading Card, you can go directly to the Battle Arena to battle him.
