Wyvern Knights are a rare breed of fighter who have formed a deep bond with a wyvern, a powerful and intelligent winged creature that they ride into battle. Through a magical bond that is forged through days of intense training and mutual trust, the fighter and wyvern become a powerful duo that is feared by their enemies and respected by their allies.

The Wyvern Knight is a master of aerial combat, using their mount's strength and abilities to dominate the battlefield from above. Their expertise in mounted combat is unmatched, and they can control their wyvern as if it were an extension of their own body. They can communicate telepathically with their wyvern up to a range of one mile, and the wyvern can understand any language spoken by its rider.

In addition to their skills as a mounted fighter, the Wyvern Knight gains unique benefits from their bond with their wyvern. Their mount gains increased hit points and the ability to use the fighter's proficiency bonus for attack rolls and ability checks. The wyvern also gains a powerful stinger attack that can poison their enemies.

As they progress along their path, Wyvern Knights become even more proficient in aerial combat. They gain the ability to take the Dash action as a bonus action while riding their wyvern, and their mount can make additional attacks on their turn when they use the Attack action. The Wyvern Knight's bond with their mount becomes so strong that their wyvern gains the ability to unleash a devastating dive bomb attack that can knock their enemies prone.

At higher levels, the Wyvern Knight and their mount become even more formidable. They gain resistance to a chosen damage type and additional hit points, and their wyvern's stinger attack becomes even more deadly. The Wyvern Knight can also use their Action Surge feature twice per short rest, and their wyvern becomes immune to the damage type that the fighter chose for their resistance.

In battle, the Wyvern Knight and their wyvern mount are a truly fearsome force, swooping down from the skies to strike their enemies with deadly precision. With their bond of trust and their mastery of aerial combat, they are a force to be reckoned with on any battlefield.
