Disgaea 3: Absence of Justice

To get this trophy, you need to kill the “Lucky Pirates” in the world of the item - these are pirates who travel on a golden boat. Like all pirates, they appear in the world of objects after level 20 and appear during the first 3 turns; if they have not arrived in three turns, you can safely move to the next level and wait for them there. "Lucky Pirates" usually appears at levels 41 to 49.
