Drake Knight
Draconic Fighting
When you first choose this subclass at 3rd level, you choose a fighting discipline from those listed below.
Dragon in Flight
The masters of this fighting discipline train themselves to preform incredible jumps, and then channel those jumps into deadly strikes.
You can make a running high jump or long jump, even if you have not moved at all this turn. You also add your Strength modifier to your high and long jumps an additional time.
If you are wielding a weapon with reach, and have jumped immediately before an attack, that attack has a bonus to hit and a bonus to damage equal to your Proficiency Bonus. This is called a Jumping Strike.
Dragon Breath
Drake Knights who specialize in this discipline have some low level magic abilities, and learn to channel the elemental powers of a dragon into their strikes.
You gain proficiency in the Arcana skill. If you already have proficiency in this skill, you gain proficiency in another skill of your choice.
You can also infuse your weapon with draconic energy for a few seconds. Choose Acid, Cold, Fire, Lightning, or Poison damage, until the start of your next turn your attacks with a weapon of your choice deals 1d6 extra damage of the chosen type. You can use this feature a number of times equal to your proficiency bonus. You regain all uses when you complete a short or long rest.
Invincible Dragon
Some Drake Knights focus less on offense, instead emulating the impenetrable defense and endurance of a dragon.
You gain a + 1 bonus to AC while you are wearing armor.
When you use your second wind bonus action, you now roll a number of d10s equal to your proficiency bonus, and add your fighter level.
Mid-Armored Movement
At 3rd level, your training has taught you how to move more quickly than the average person, even when burdened by most armors.
When you are wearing medium or light armor, or no armor at all, your speed increases by 10 feet.
Draconic Resilience
At 7th level, you have exposed yourself to certain elements, and have gradually built up a resistance to them.
You gain resistance to one damage type of your choice from the following: Acid, Cold, Fire, Lightning, and Poison.
When you reach 15th level, your experiments with draconic magic grant you immunity to the chosen type.
Advanced Draconic Fighting
At 10th level, your training in your chosen fighting discipline has granted you the following benefit:
Dragon in Flight
You are at home in the air, and have mastered quick takeoffs and landings.
You no longer take fall damage from falling 20 feet or less, and your high jumps can cover a horizontal distance equal to 10 feet if it is a full jump.
If you end a jump within 5 feet of an enemy creature, you can make another jump away from that creature without provoking opportunity attacks, although you must still have the required movement. You must end the jump at least 10 feet farther from the creature than you started. Any of these jumps can be Jumping Strikes.
Dragon Breath
You have learned to focus your control over draconic magic, increasing its range and power.
When you infuse your weapon with draconic energy, the weapon's range is increased by 5 feet, and deals extra damage of the chosen type equal to your Charisma modifier.
Invincible Dragon
You have learned to channel the unbreakable will of a dragon.
You gain one Legendary Resistance. If you fail a saving throw, you can use your Legendary Resistance and choose to succeed instead. You regain your Legendary Resistance when you finish a long rest.
Intimidating Presence
You now exude the fearsome aura of a dragon, striking fear into the hearts of your enemies.
At 15th level you can use an action to give off a Fearful Presence. Each creature of your choice within 120 feet of you, and that is aware of you, must make a Wisdom save equal to 8 + your Charisma Modifier + your Proficiency Bonus, or become frightened of you for 1 minute. A creature can repeat the saving throw at the end of its turn, ending the effect on a success.
Once you have used your Intimidating Presence Feature, you must complete a long rest before you can use it again.
Masterful Draconic Fighting
You have completed your training, and now embody the powers a dragon.
At 18th level, your training has improved you original fighting discipline as shown below.
Dragon in Flight
When you make a Jumping Strike, you score a critical hit on a 19 - 20. Furthermore, when you use your action surge, your speed is doubled until the end of your turn.
Dragon Breath
You can use your action and expend one use of your Dragon's Breath Discipline to expel the energy out in a 30 foot cone, dealing 4d6 + your Charisma modifier of your chosen damage type to all creatures in the cone. These creatures get to make a Dexterity Save equal to 8 + your Charisma modifier + your Proficiency Bonus, taking half damage on a successful save.
Invincible Dragon
Your AC increases by 1 when you are wearing armor.
Additionally, when you use your second wind, you gain resistance to all damage until the end of your next turn.
