Pirate Map

The Pirate Map can be dropped by any enemy in and close to the ocean during hardmode. It summons a Pirate Invasion when used, which can be used to gain the Pirate vanity set and weapons.

Farming
If you have acquired some statues, like the goldfish, the jellyfish, the piranha or the birds there is an very fast way of farming the map. You need a switch, wire, dart traps, and any of the statues mentioned.
 * Wire the statues and the traps to a switch in the same wire-system.
 * Craft a 1 second timer (If you use some fish-statues, you'll have to place this system in water with birds or bunnies you can use land).
 * Place the traps so that they kill the mobs.
 * Flip the switch
 * Grab a snack and wait
