Horned Wyvern (5e Creature)
From D&D Wiki
Large dragon, unaligned
Skills Perception +5
Trampling Charge. If the wyvern moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, that target must succeed on a DC 18 Strength saving throw or be knocked prone. If the target is prone, the wyvern can make one stomp attack against it as a bonus action.
Flyby. The wyvern doesn't provoke opportunity attacks when it flies out of an enemy's reach.
Multiattack. The wyvern makes three attacks: one with its bite or gore and two with its claws.
Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 20 (4d6 + 6) piercing damage and the target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.
Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d6 + 6) slashing damage.
Stomp. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 10 (1d8 + 6) bludgeoning damage.
Gore. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 19 (3d8 + 6) piercing damage.
Fire Breath (Recharge 5-6). The wyvern exhales fire in a 30-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw, taking 22 (4d10) fire damage on a failed save or half as much damage on a successful save.
The powerful horned wyverns that dwell on the high mountains are brutish flying terrors and distantly related to sea drakes and cockatrices. These powerful adversaries enjoy charging their enemies and trampling them, especially off cliffs as well as using their potent fire breath to set dry wild grasses on fire to create wildfires to engulf stubborn enemies hiding in their mountainous homes. Their hides are generally a mixture of incredibly bright scarlet red scales with thick black or golden manes of fur on the back of their necks and hanging from their throats.
