Imperfect Flight. While bloodied , the wyvern’s fly speed is halved, and it can’t gain altitude.


Multiattack. The wyvern attacks once with its bite and once with its stinger. While flying, it can use its claws in place of one other attack.

Bite. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (2d4 + 4) slashing damage. If the wyvern is attacking from above, the target is grappled by the wyvern (escape DC 15). While grappling a target in this way, the wyvern’s Speed is reduced to 0, it can’t use its claws to attack any other creature, and it has advantage on attacks against the target.

Stinger. Melee Weapon Attack: +7 to hit, reach 10 ft., one creature. Hit: 11 (2d6 + 4) piercing damage. The target makes a DC 15 Constitution saving throw , taking 24 (7d6) poison damage on a failure or half damage on a success.


A wyvern begins combat by attacking from above, using its claws and stinger. When bloodied, it lands and attacks with its bite and stinger. It flees only if it is blinded , poisoned , or afflicted with some other condition that reduces its combat capacity.

Legends and Lore

With an Arcana or Nature check, characters can learn the following:

DC 10 Though related to dragons, wyverns are less intelligent than their true dragon counterparts.

DC 15 A wyvern’s tail is tipped with a stinger that drips a deadly poison.

DC 20 Slipping a gold ring onto a wyvern’s toe tames the beast.


Sometimes referred to as false dragons, wyverns are easily differentiated from their larger, more intelligent kin by their limbs: whereas true dragons have four legs and a thick tail, the wyvern possesses only hind legs, and its whip-like tail is tipped with a poisonous stinger.

Bestial Cousins. While true dragons are wise, resourceful creatures, wyverns rely heavily on animal instinct and territorial aggression. Their single-minded pursuit of prey makes them difficult to escape but easy to outwit.

Vicious Mounts. In ages past, elite wyvern cavalry clashed with griffon riders and other aerial combatants. Nowadays, few chance the perils of capturing, raising, and taming wyverns. They’re almost as dangerous to their riders as to their enemies. A captive wyvern’s upkeep is also outrageously expensive: some wyverns eat as many as three cows a day, and sometimes a farmhand for dessert. Legend has it that a person who slips a gold ring onto the toe of a wyvern will win its lifelong devotion, but few wyvern wranglers are reckless enough to try.
