In *Kingdom Come: Deliverance 2*, the "Canker" side quest is accessible early in the game, and you must first complete "The Jaunt" to unlock it. This quest is a great opportunity to acquire a mace or some extra Groschen, so let’s guide you through the steps to complete "Canker."
Pick Up the Canker Side Quest
Find and Kill Canker
The bandit camp where Canker resides is nestled in the mountains, and it's easy to overlook because you need to navigate through a narrow gap to reach it, similar to accessing the Hermit's house during the "Wedding Crashers" quest. Ensure you're prepared for combat before entering, as you'll face several bandits alongside Canker.
During the battle, some bandits might flee depending on the order in which you take them down. However, it's important to eliminate most of them, so don't assume you can avoid fighting everyone. Fortunately, Canker will not escape, allowing you to complete your objective by killing him.
Finish the Quest and Return to Gules
After defeating Canker and his companions, loot Canker's body to obtain the Light Mace as proof of your success. Feel free to take any additional items that catch your eye. Then, head back to Gules to complete the quest.
Once you've finished "Canker" in *Kingdom Come: Deliverance 2*, you'll need to wait a full in-game day before you can pick up the next quest involving Gules' old bandit friends. After the day has passed, speak with Gules to start "Handsome Charlie."
