How to Find Lost Items?

Attack Civilians for Lost Items

The easiest way to obtain Lost Items is by attacking civilians. Hit a civilian first, and if they retaliate, continue attacking them multiple times until they randomly drop an item. Defeated civilians can drop consumables and, occasionally, Lost Items.

Tip!	You can also use Chiz while farming Lost Items from civilians. Her Basic Attacks allow you to earn additional Fons each time you attack civilians, making the farming process more efficient.

Mind Your Wanted Level

Attacking civilians increases your Wanted Level. Before it reaches the first star threshold, return to your Apartment to have Anomaly Furniture "Coocoo Alert" clear your warrant. Alternatively, you can use Goodheart Crispy Mouse Cookie to reduce your warrant level by 500.
