Dragon Knight Subclass

A heavily clad knight walks through the town. The townsfolk make way with fear in their eyes. She hears a scream in the middle of the town and she rushes to the source. A man, the governor, just executed another man for stumbling before him; eyes of rage burn behind her intimidating helmet. She leaps and strikes at the governor; he retracts and tries to cast his spells, to no avail. She grabs the man by the neck, and her cloak spreads out, shifting into wings as she launches into the air. She calls out to the wind, then throws the man downwards; as he falls his last sight is the maw of an ancient dragon. She lands upon her companion, then departs.

Atop a misty mountain, a group of refugees cower as the man before them, an elf, battles the blue dragon that has destroyed their town. He lunges and spews out a massive bolt of lightning, taking out the dragon's eye; He walks to the injured creature. The enslaved child of his enemy lands at his feet. He waves his hand commanding it to protect the villagers. It shields them with its body. In a last ditch effort, a crack of lightning is expelled from the downed foe, directly at the knight. He falls, and for a moment the dragon sees victory. The knight slowly rises. Renewed by the assault, he commands his subject to merge with himself; he crackles with lightning and flies at his foe, caught in a death embrace, as they both fall to their doom.

Among a horde of demons are a warrior and his trusted friend, a scarred silver dragon. He spins his lance around, hitting several of his enemies, to little avail, and as a last ditch effort he expels a wave of ice all around him, killing several of them; he then commands his dragon to brutally assault the remaining demons. Their destruction grants them a small reprieve. He pulls out his axe, takes a deep breath, soars up into the sky with his trusted steed, then jumps to what seems to be certain doom. As he lands, the earth shakes and his enemies fall to the ground. He rises up and looks to the army charging them; he looks back and sees his friend's nest: the last of the silver dragons, not yet even born. He looks to his friend once more, and smiles.

Level 3: Dragon Companion

Starting at 3rd level, you gain a dragon companion. It is friendly to you and your companions, and it will listen to your commands as best it can. Your dragon ages magically, growing in power and size as you gain levels in this class. See the dragon's game statistics detailed in the section Creating Your Dragon below.

In combat, the dragon shares your initiative, taking its turn immediately after yours. The dragon can move and use on it's own, but the only action it takes on its turn is the Dodge action, unless you use your reaction to command it to take one action describe in his stat block. In order to command your dragon, you need to be able to communicate with it. If you are incapacitated, absent or unable to give commands, your dragon acts on its own.

When you take the Attack action on your turn, you can chose to forgo your attacks to command the dragon to attack instead. You make this choice for each attack. Your dragon cannot use the same natural weapon more than once in each of its turns, no matter the number of attacks you can make.

The dragon knight can communicate telepathically with his dragon, up to a range of 100 feet.

In addition, you can read, write and speak in draconic. If you already know this language, your dragon learn one of the languages you know.

When your dragon is reduced to 0 hit points, it makes Death Saving Throws as any other player. If it dies, you can bring it back by spending 10 gp in treasure (gems, precious metals and such) per level, on a ritual that lasts 8 hours.

Alternatively, you can spend a number of hit dice equal to your level to bring the dragon back as an action.

Lord's Direction
At 3nd level, your command over your dragon companion improves. Whenever you hit a creature within 5 feet of your dragon with an attack, you can command him to make an attack using your reaction.

In addition, whenever a creature moves out of your dragon's range, you can use your reaction and command him to make an opportunity attack.

Whenever you are riding your dragon and decide to use the rules for controlled mount. The initiative of your dragon changes to match yours when you mount it. It moves as you direct it, and it has only three action options: Dash, Disengage and Dodge. Your dragon can move and act at the same turn you mount it. All the other rules for mounted combat apply.

While mounted, you have advantage on attack rolls against any unmounted creatures smaller than your dragon. Also, you can add half of your proficiency modifier as a bonus to your attack and damage rolls, when making weapon attacks while riding your dragon.

In addition, if your dragon is targeted by an attack, you can force the attack to target you instead.

Level 15: Dragon's Legacy

Level 18: Draconic Likeness

At 20th level, you become able to polymorph into dragon-like hybrid creature. As a bonus action, you can manifest two of the following draconic traits: claws, scales, wings or tail. You keep manifesting the traits until you change to conceal them or change for two another traits, with a bonus action.

You can make attacks with your natural weapons as part of your Attack action, using your dragon's damage die for its medium size. Any draconic traits applied to the dragon claw, scale, wing or tail also apply to your manifestation of them. They grant you the following benefits:

Claws. Your fingernails turn into claws. The claws are considered light weapons you are proficient with.
