In *Kingdom Come: Deliverance 2*, the "Canker" side quest is an engaging early-game mission that you can unlock after completing "The Jaunt." This quest not only offers the chance to acquire a mace but also some extra Groschen, making it a worthwhile endeavor. Here's a detailed guide on how to successfully complete the "Canker" quest.

Pick Up the Canker Side Quest

To initiate the "Canker" quest, you'll need to have a conversation with Gules at Semine. A convenient time to pick up this quest is during the wedding of Lord Semine and Agnes. You can approach Gules while he's enjoying a drink before the ceremony and start the quest. Alternatively, you can find Gules on patrol in Semine and speak with him about his past as a bandit leader. Express your willingness to help him eliminate his former associates, and he'll direct you to your first target: Canker.

Find and Kill Canker

Once you accept the quest, Canker's location will be marked on your map, situated north of Nebakov Mill. Be cautious as the path to this location is often patrolled by bandits who may attempt to ambush you. You can choose to sneak past them, engage in combat, or simply flee. While these random bandits are generally not difficult to defeat, it's best to avoid unnecessary fights to conserve your health for the upcoming battle.

Canker's camp is nestled in the mountains and can be tricky to find. You'll need to navigate through a narrow gap to reach it, similar to accessing the Hermit's house during the "Wedding Crashers" quest. Prepare for combat before entering, as you'll face several bandits alongside Canker. The bandits may attempt to flee depending on the order in which you engage them, but it's crucial to eliminate most of them. Fortunately, Canker will not run away, ensuring you can complete the quest by killing him.

Finish the Quest and Return to Gules

After defeating Canker and his crew, loot his body to collect the Light Mace, which serves as proof of your success. Feel free to take any other items you find valuable. Once you have the mace, return to Gules in Semine to complete the "Canker" quest.

Upon finishing the "Canker" quest in *Kingdom Come: Deliverance 2*, you'll need to wait a full in-game day before you can pick up the next quest related to Gules' former bandit associates. After the day has passed, speak with Gules again to start the "Handsome Charlie" quest.
