Wyvern

Wyverns are large Hardmode enemies that spawn at high altitudes. They resemble oriental dragons, are long and white, and follow the Worm AI. They are immune to the Poisoned, On Fire!, Cursed Inferno, Venom, Shadowflame, and Confused debuffs. Arch Wyverns are the bronze-colored -exclusive variants.

Wyverns spawn at any lateral map location, day or night, but generally at Floating Island altitudes. They will follow descending players down to ground level, and can fly through blocks, but tend not to fly below ground unless they are Arch Wyverns. A Wyvern will not spawn if another one is already alive, and like most enemies able to pass through tiles, it will not be able to spawn if the player themselves stays in front of player-placed walls, even if there are valid spawn points for the Wyvern. Outside of Crimson, Corruption, and Dungeon biomes, and except during events, having at least one NPC near the player will also prevent them from spawning.

Tips

 * Killing Wyverns can be hard for new Hardmode players, so its recommended to stay away from them until better armor and weapons can be obtained.
 * As with any multi-segmented enemy, piercing and explosive weapons can strike multiple segments at once, dealing several times their normal damage.
 * Using a bow or repeater with Jester's Arrows is a good way to kill the Wyvern.
 * Another useful item for killing Wyverns and other worms is the Nimbus Rod.
 * Dodging a Wyvern is crucial, as it is capable of inflicting significant damage.
 * Minecarts and the Unicorn Mount are both faster than a Wyvern.
 * The head of a Wyvern has lower defense than its tail or body segments, making it more vulnerable to damage as it charges the player. However, the head also deals twice the damage as the rest of the body on contact, making it risky to face a Wyvern head on.
 * It is easier to fight a Wyvern in Space, as the low gravity helps to dodge its attacks.
 * On the version, Wyverns do not despawn when all players die, unlike most other enemies/bosses.

Trivia

 * Although the name "" refers to a type of western dragon depicted as having two wings and two hind legs, but no arms or forelegs, Terrarian Wyverns are shaped after s in Chinese folklore.
 * The Angler mentions in a quest that Wyverns are born and raised as tadpoles called.
 * Wyverns take knockback, while Arch Wyverns do not.
 * The Wyvern strongly resembles Haku's dragon form from the 2001 Japanese animated coming-of-age fantasy movie  (image).
