"Canker" is an engaging side quest you can tackle early in Kingdom Come: Deliverance 2, but you'll need to complete "The Jaunt" first. This quest not only offers a chance to snag a mace but also some extra Groschen, making it a worthwhile endeavor. Here's a detailed guide on how to successfully complete "Canker."
Pick Up the Canker Side Quest
Find and Kill Canker
Canker's bandit 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 a fight before entering, as you'll confront several bandits alongside Canker.
The bandits might flee depending on the order in which you take them down, but you'll need to eliminate most of them. Fortunately, Canker stays put, ensuring you can complete the quest's primary objective 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 is essential to prove you've fulfilled your task. Feel free to take any other items you find valuable. Once you have the mace, head back to Gules to conclude the "Canker" quest.
Upon completing "Canker" in Kingdom Come: Deliverance 2, you'll need to wait a full in-game day before you can proceed with the next quest involving Gules' former bandit comrades. After the day has passed, speak to Gules again to pick up the quest "Handsome Charlie."
