Pirate Map

Not to be confused with Treasure Map. The Pirate Map is a Hardmode item used to summon a Pirate Invasion. It has a 1% chance of dropping from any enemy within or close to an Ocean during Hardmode).

Tips

 * With Neptune's Shell and permanent Minions, along with any minion boost gear available (such as Spider armor), stand on the Ocean floor while the minions kill incoming enemies. Use Battle Potion and place a nearby Water Candle to speed up the process.
 * In Crimson worlds, place a contained area of Crimson to one side of the Ocean so Blood Jellies spawn, which will be more frequent than ordinary Ocean spawns. Take advantage of Blood Moons to further increase spawn rates.
 * If the Jungle is close enough to the Ocean that you can be inside the Jungle Biome, it will spawn Arapaimas frequently in the Ocean. Alternatively, you can create artificial Jungle if you have Jungle grass seeds.
 * You can kill the Pirate Invasion in the Ocean to get pirate maps from the pirates. Then you can just farm the Pirate Invasion over and over again.
 * An easy way to farm Pirate Maps is by placing at least 50 Meteorite in 2 or 3 layers above the ocean, standing near or on these blocks (make sure Meteor Heads spawn) and spawning in minions.
