Dragoon Conclave

You have become an especially deadly huntsman while on the saddle. Swift as the wind and with imposing stature, you let no prey escape. Though you are a powerful fighter while on your own, while on your steed your skills are pure devastation. Your partnership with a mount is not an exclusive one, as you are able to quickly and easily befriend a new steed whenever needed. Your amazing skills are not completely to your own credit however. As with your close connection to nature, it's compassion and understanding that your mount has for you that allows you to reach your fullest potential.

Mounted Huntsman

Starting at 3rd level, you’ve learned how to control and work with beasts to enhance your combat potency by utilizing the creatures naturally enhanced speed and size. You have advantage on saving throws made to avoid falling off your mount. If you fall off your mount and descend no more than 10 feet, you can land on your feet if you aren’t incapacitated. Mounting or dismounting a creature costs you only 5 feet of movement, rather than half your speed. You also have advantage on any dice rolls made to heal your mount.

Finally,  if your mount is brought to 0 hit points, you can use your reaction to make a medicine check to cause it to instead remain at 1 hit point. The DC is equal to the damage taken, and increases by 5 every subsequent check made until you fail.

Faithful Steed

Upon choosing this archetype at 3rd level, you can more easily garnish favor with beasts, in order to make them your steed. You now have proficiency in animal handling. If you already have proficiency in animal handling, your bonus becomes double.

At 5th level, you add the spell find steed to your known spells. At 13th level, you add find greater steed. The spells count as a ranger spell for you but don’t count against the number of ranger spells you know.

Deft Rider

At 7th level, you are able to nimbly dart through the battlefield.  While mounted, any target you hit with an attack must make attacks of opportunity against you with disadvantage until the start of your next turn.

Additionally, you and your mount share the same AC. The lower of the two being raised to match the higher value.

Vantage Point

Starting at 11th level, your heightened perspective allows you to notice weaknesses in your enemies defenses more easily. While mounted your attack rolls critically strike on a roll of 19 or 20.

You also have advantage on sight based perception checks while on a mount.

Unbreakable Bond

Once you reach 15th level, you steed knows you’d risk your own life to protect it, and is willing to respond in kind. If you drop to 0 hit points while mounted, you can use your mounts reaction, causing it to reduce the damage that knocked you unconscious in half, and your steed takes this damage in your place.
