Early in *Kingdom Come: Deliverance 2*, the “Canker” side quest becomes available after completing “The Jaunt.” This quest offers a chance to acquire a mace and some Groschen. Here's how to complete it:

Picking Up the “Canker” Side Quest

To begin, speak with Gules in Semine. Conveniently, you can initiate this quest during Lord Semine and Agnes's wedding, while Gules is enjoying a drink. Alternatively, find him on patrol in Semine. Simply ask about his former bandit gang and offer your assistance in eliminating them. Canker is your first target.

Finding and Killing Canker

Upon accepting the quest, Canker's location—north of Nebakov Mill—will appear on your map. Be prepared for potential ambushes from bandits along the path. You can choose stealth, combat, or a hasty retreat. While individual bandits aren't overly challenging, repeated skirmishes can deplete your health before the main encounter.

Canker's bandit camp is nestled within the mountains, easily missed due to a narrow passage. Similar to accessing the Hermit's house in “Wedding Crashers,” careful navigation is required. Prepare for combat before entering, as several bandits, including Canker, await.

Note that some bandits may flee depending on the order you eliminate them. However, thorough combat is advised to ensure the quest's completion, as Canker himself doesn't run.

Completing the Quest and Returning to Gules

After defeating Canker and his cohorts, loot Canker's body. While you can take other items, you must acquire the Light Mace to fulfill the quest's objective. Return to Gules to complete “Canker.”

Following “Canker,” a full in-game day must pass before the next quest in the Gules storyline, “Handsome Charlie,” becomes available. Speak with Gules again after this delay to proceed.
