💡 Strategy

Pro Tip: Void Mayonnaise is not a strong profit item compared to other artisan goods, but it is essential for progression in the Witch’s Swamp questline.

Process Void Eggs into Void Mayonnaise for better returns than selling the eggs raw.
Keep at least one Void Mayonnaise in storage for the quest requirement.
Useful as a recurring gift for Krobus to build friendship quickly.
