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.

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, as at the minimum depth Harpy is a rare spawn where other monsters can spawn in its place still, where at the top of the map there is nothing but Harpies.

The Harpy monster uses the obvious Flying AI but with a twist. Instead of just ramming into the target like a Hornet or Demon Eye would, the Harpy attempts to ram the target and also shoots volleys of 3 feather-like projectiles. These feathers cannot be deflected with a weapon and do 30 damage. When it rams into the player the damage is slightly less, dealing 25 damage. 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 it unleashes an endless fury of feathers at you.



Drops
When killed, the Harpy's body is destroyed leaving nothing but its wings on the ground and a few coins.


 * Around 500 Copper Coins.

Tips and Tricks
One way to fight Harpies is to construct a large platform in the air 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 requires no additional work.
