- "Wyverns are unlucky to be frequently mistaken for dragons. Seeing a reptile approaching a flock of sheep, peasants panic. They expect it to breathe fire, massacre everyone and abduct the local virgins. While it is true that wyverns hunt sheep, they neither breathe fire nor lay waste to whole villages. And they are completely indifferent to virgins."
- Developer CD Projekt's characterization of the wyvern taken from the Monsterbook which was enclosed with the Collector's Edition of the computer game "The Witcher" for Poland, Hungary and the Czech Republic:
- Ordinary folk often mistake wyverns for dragons. Witchers, however, immediately recognize these flying lizards, which tread upon the ground on two heavily-muscled legs. They also know that when fighting this beast, they must avoid the venomous stinger at the end of its tail and its jaws that bristle with deadly teeth.
- The concept for the wyvern emerged from the human fear of reptiles. With its flat head and long neck, the creature resembles a snake; its extended tail only strengthens this impression. The dinosaur-like hump on its back makes it all the more terrifying. The bright colors of the sketch immediately suggest a venomous creature. Thin, long spikes seem to protrude directly from its curved spine, and along with the beast's general posture serve to emphasize its malicious and treacherous nature.
- If you are not a witcher, you had better not mess with the wyvern.
- On one of his quests, Geralt has a chance to fight alongside a group of these beasts. It is a pleasure to witness the destruction they spread amongst foes unfamiliar with the ways of fighting these fearsome creatures.
- In Chapter III, Geralt can talk with a Townswoman sitting at The New Narakort. She is blonde and wearing a green dress with a yellow shirt, telling him she is in the mood to spin a tale but she is thirsty. Depending on her mood, she will ask for "a mug of beer" or milk, informing Geralt about Basilisks, Wyverns and eventually Archespores.
- Geralt must exit and then re-enter the inn (or meditate) after each tale to speak to her again. After Geralt has acquired all the entries she knows about, she will still ask for milk and beer but will not part with any new tales or journal entries.
- Their remains will contain Wyvern meat with or without their bestiary entry.
- The Wyvern Contract requires three wyvern steaks.
- Hungry Like a Wolf (The Price of Neutrality premium module) also requires three wyvern steaks.
A single strike from this carries risk of poisoning from powerful toxins. Even a Witcher will experience wrenching pain when injected with the venom, so preparing ahead of time with Golden Oriole is suggested.
- Most dangerous of all are the royal wyverns. Or, as they're called in some circles, the royal pains in the arse.
– Albina Tottelkampf, lecturer in natural sciences at Aretuza
- Wyverns are often mistaken for dragons, and, though they are much smaller than their more famous kin and do not breathe fire, they are likewise extremely dangerous monsters. Especially feared are the so-called royal wyverns who, like their namesake monarchs, are exceptionally ornery and extremely deadly.
Wyverns are quite venomous, they are able to spit their venom from a distance and even inject it directly into its victim through the stinger on the end of its long tail, the use of Golden Oriole can prevent it from incapacitating you. They will fly around their prey, well beyond Crossbow range, before they will swoop down at break neck speeds in an attempt to claw at their victim.
Once on the ground a wyvern will prefer to strike with the talons on its feet, its teeth and its tail. It is possible to parry the bites, but if unsuccessful the consequences can be deadly. The don't appear to be very good at dodging while on the ground; an unending series of Fast attacks has been seen to keep them off balance so they don't attack right to the point that they die.
