Pirate Map

The Pirate Map is a Hardmode item used to summon a Pirate Invasion. It has a 1% (1/100) 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 overlap the Ocean, Arapaimas will spawn frequently. A Jungle can be created artificially near the Ocean.
 * In Corrupt worlds, it is helpful to corrupt the Ocean using Unholy Water or a Clentaminator and grind the Eater of Worlds for maps. Since there are about 50 parts per boss, around every 2 bosses will probably drop at least one map.
 * If the Pirate Invasion is fought in the Ocean biome (platforms or bridges will help), the numerous pirates will likely drop several maps for each invasion. (Note: This requires a town NPC's home or a spawn point near the ocean).
 * If there is a Floating Island above an ocean, Harpies and Wyverns can drop Pirate Maps.

Trivia

 * On the, the player is holding a Pirate Map on the app icon.
 * The Pirate Map plays the same sound as the boss-summoning items (Suspicious Looking Eye, Mechanical Skull, etc.) when used.
