Wyvern

Wyverns are large Hardmode enemies that spawn at high altitudes. They resemble oriental dragons, are long and white, and follow the Worm AI.

Wyverns spawn at any lateral map location, day or night, but only at Floating Island altitudes. You will know if the conditions are right for Wyvern spawning if you see Harpies, as both spawn under the same conditions, though Wyverns spawn much less often. The spawn rate for both enemies increases the higher up one gets.

Tips
For more strategies on defeating Wyverns, see Guide:Harvesting Souls.


 * Wyverns attack like Devourers and Bone Serpents, except from above; they make long, sweeping passes. When the Wyvern moves off-screen, expect it to come diving back down from the top of that part of the screen.
 * Fighting Wyverns can be difficult, as they deal respectable amounts of damage, are very fast, and continue homing in on the player almost until making contact, which makes dodging difficult. Fighting them at high altitude or even in Space, taking advantage of the lower gravity for longer jumps and falls, is useful for dodging. Try to time jumps so that you're falling when the Wyvern is close to making contact. Equip all available jump-boosting Accessories. Gravitation Potion and Swiftness Potion will also help.
 * As with any large enemy, ranged and "semi-ranged" weapons that pierce targets for multiple strikes (eg. Demon Scythe, Dao Of Pow) are more effective. The Demon Scythe can be especially useful, as it not only pierces but also has unlimited range, and the Wyvern may commonly be off-screen for much of the fight. The Clockwork Assault Rifle is also effective. With good armor and a few Ironskin Potions, a Spear or Chainsaw can also be effective. If you've already defeated The Twins, the Magical Harp is also very effective.
 * In an enclosed area, spamming a weapon that ricochets off walls can prove quite effective.
 * With a long sky bridge and Hermes Boots or Spectre Boots, and the Demon Scythe, running continuously in one direction can keep the Wyvern behind you for longer periods, allowing a long-range weapon to be spammed behind you. The Wyvern will still get in front of you often, but this method provides more solid attack time.
 * A set of Cobalt Armor or better is enough protection when dealing with a Wyvern, providing the player can dodge its attacks. The low gravity of Space makes this much easier.
 * When using a Repeater and piercing Arrows, aim for the Wyvern's head while it is diving to attack. This will hit it multiple times and cause large amounts of damage.
 * When using a Spear-type weapon, try to hit the Wyvern right after dodging its attack to hit multiple times.
 * Like all Worm enemies, the drops from a Wyvern drop from its head. Since Souls of Flight float, it is possible to lose them off screen and render them non-collectable.
 * If you have a Demon Scythe,use a Gravitation Potion and float into space. When the Wyveryn first attacks, wait for it to go almost completely off-screen then fall downwards which will make the Wyveryn follow you vertically. By constantly firing your Demon Scythe at the ground, the Wyveryn will take damage rapidly due to the piercing effect the Demon Scythe has and it will quickly finish it off.
 * A Star Cannon is also very effective while dodging with Spectre Boots because it can pierce multiple sections

Trivia

 * Although the name "wyvern" refers to a western dragon depicted as having two wings and two hind legs, but no arms or forelegs, Terrarian Wyverns are shaped after Chinese dragons in Chinese folklore, called 'Lung Dragons' in Dungeons & Dragons.
 * Because of their color, body shape and general style, Wyverns bear a close resemblance to several dragons from popular culture. Notable examples are:
 * Haku's true form, from the animated film Spirited Away.
 * Fuchur (known as Falkor in the English translation) from Michael Ende's "The Never Ending Story".
