Below is a walkthrough for the Hunting for Ingredients support request in The Legend of Heroes: Trails from Zero. To obtain this request, interact with the terminal in the SSS building during Chapter 1.
Client: Oscar
Salary: 1500 mira
Speak with Oscar at the Morges on West Street. He’ll need you to gather Fish Fillet x4 and Monster Eggs x3. The Monster Egg ingredients can be found in East Crossbell Highway. They are a rare drop from the Egg Snake and Metal Saucer monsters. The Fish Fillet ingredients can be found in the third area of Ursula Road. They are dropped by the Backlash monsters. Once you’ve gathered the ingredients, return to Morges on West Street and speak with Bennet (girl on left side of the bakery). Afterwards, speak with her again then hand over the ingredients. You’ll then need to speak with Oscar behind the counter and hand over the ingredients to complete the quest. Make sure to then turn it in at the terminal!
