Royal Wyvern - The Witcher 3

In the end the witcher slew the hideous creature, though not without some difficulty. Thanks to this feat, the soldiers could once again send shipments of the food and equipment needed to conduct the war. Whether that was a good or bad thing - that is an entirely different matter.

It were huge. And those teeth, ugh! We barely escaped.
Wonder if it killed the traders… Whoresons sure had it comin'.

A hunter who knows his prey's habits and behavior will rarely return from his hunt empty-handed. To know what forest paths deer are like to trod, to know in what muck boars will wallow, to guess when a hare will emerge from its burrow - that is half the battle.

What most men do not know is that some monsters also possess such knowledge. For example, a royal wyvern from Velen had learned the danger of exposing itself to human eyes and arrows by flying high to pick out its prey from afar. Instead, it would lurk by the roadside and wait for military transports. In this way it grew fat on salted pork and beer, expanding until it resembled a dragon more than other, lesser members of its own kind.

The witcher thus knew this beast would be much stronger and more resilient than a normal wyvern. Even one blow from it could kill - which is why he would need to avoid its charge at all costs. He would also be wise to force it to the ground with his crossbow or a bomb whenever it tried to fly into the air and hurtle down in a deadly dive.
