Harpy



Harpies are flying enemies added in the 1.0.4 patch. They spawn at high altitudes, typically between the height of Floating Island and the top of the map.

Information
Harpies can spawn in both day and night although the spawn rate is slightly lower during the day while during dusk and night time Harpy attacks are very active. During dawn the spawn rate begins to diminish and when it becomes daytime the spawn rate becomes around 50% of night times spawn rate. Their spawn rate occurs more often the closer you are to the top of the map. Additionally, they can only spawn a certain distance away from the center of the map; about a thousand blocks or so.

The Harpy monster uses the Bat AI but with a twist. Instead of just ramming into the target like a Jungle Bat or Hellbat would, the Harpy attempts to ram the target and also shoots volleys of 3 enemy projectiles called Harpy Feather. These feathers can be deflected with a weapon and deals 30 damage to an unarmored player. When she rams into the player the damage is slightly less, dealing 25 damage to an unarmored player. The feathers are destroyed on contact with any block or after it travels a certain distance it will break apart.

There can be up to 7 Harpies attacking you at once during the day time. At night you can have up to 10 Harpies attacking you at once and during Blood Moon you can up to 15 Harpies attacking you at once. They tend to eventually group together in 1 single bunch if left alive, probably a bug with its AI. This makes it seem like she unleashes an endless flury of feathers at you.

Drops

 * Feather: 20% (1:5 chance)

Tips
One way to fight Harpies is to construct a large platform near the top of the map with the ability for harpies to pass on top of it. Using regular blocks means that you have to create large enough openings for the Harpies; using wooden platforms allows them to come up through the platforms but also leaves you vulnerable to attacks below. You can also build a mob grinder.
