Embarking on the "Into the Underworld" main quest in Kingdom Come: Deliverance 2 often leads you to stumble upon the side quest, "Feast for the Poor." This begins with a conversation with Chenyek. After assisting him by defeating Goliath, express your interest in working with him. Select the dialogue option, "I’ll drink to it," to officially begin the quest.
Securing Sigismund's Sausages

Next, deliver a sausage to Beggar Damian, located outside a tavern in Kuttenberg's southeastern area, near the fast travel point. After this delivery, your objective shifts to speaking with Knuckles.

Aiding Knuckles
Choosing Knuckles' path involves retrieving wine from the same camp where you obtained the sausages. Locate a chest concealed within a straw structure in the camp's center. Be warned: this chest is secured with a "very hard" lock, requiring proficient lockpicking skills.
Complete "Feast for the Poor" by returning to your chosen benefactor. Afterwards, you can proceed with other side quests, such as "In Vino Veritas," or resume the main storyline.
Kingdom Come: Deliverance 2 is available now on PlayStation, Xbox, and PC.
