Wyvern

Wyverns are long, white, oriental-dragon-like creatures which appear at certain heights on Hardmode (typically at or above the Floating Island level) and can even spawn directly above the start point of a map. The wyvern spawn rate increases the higher up you get.

The Wyvern attacks like a Devourer or Bone Serpent, making long, sweeping passes. Fighting them at high altitude and taking advantage of the lower gravity is useful for dodging, since they can do a lot of damage quite quickly. Weapons or Spells that strike a target multiple times (ex; Demon Scythe) are your best bet for fighting the Wyverns, as with any other worm.

Fighting the Wyvern
Fighting wyverns can be difficult as they deal respectable amounts of damage and are very fast. A wide variety of tactics are effective. The Clockwork Assault Rifle is extremely effective when coupled with the Rocket/Spectre Boots. With good armor and a few Ironskin Potions, a spear can also be quite effective. Magical Harp are considered the best magic weapon to deal with the wyverns.

If you are in an enclosed space like a house, spamming a weapon which bounces off walls can prove quite effective since the wyvern will fly right through the walls of the house to attack you.

Note

 * If you are above or close to your house and are fighting a wyvern, and you use Magic Mirror to teleport back, the wyvern will follow you to your house/spawn point.

Trivia

 * The body design and color pallet of the Wyvern seems to indicate that it is a direct reference to the character Haku (in his dragon form), from the animated feature Spirited Away.
 * The dragon is not, strictly speaking, actually a wyvern. A wyvern is described as a Western dragon with two legs and a pair of wings, while this dragon is Eastern and has four legs and no wings.  It is closest in relation to the Asian lung dragon.
 * The body and facial styling along with the color pallet closely represent Falcor from "The Never ending story"
 * It is a common annoyance to many players with high towers or floating islands.
