The Falconer

Just as a beastmaster works in partnership with a bonded animal, a falconer hunts in tandem with a trained bird of prey. Unlike beastmasters, falconers are welcome in cities since a trained bird is more acceptable in a populated area than a wild predator. Falconers are fierce hunters who develop a close bond with their hunting bird, and that bond gradually strengthens with time and magic until the two hunters are inseparable.

Hunting Bird

At 3rd level, you learn to use magic to forge a powerful bond with a bird of prey. By performing an 8-hour ritual which expends 50 gp worth of herbs and food, you summon forth a bird from the wilderness to serve as your loyal hunting companion. The bird can be a falcon, a hawk, an eagle, or some other bird of prey, but regardless of species, it uses the stat block of a Hunting Bird.

You can only have one hunting bird summoned at a time. If your hunting bird is ever slain, you can return it to life with a ritual that takes 8 hours and requires the expenditure of 25 gp worth of herbs. You can return a hunting bird to life this way even if you do not possess any part of its body.
Add your proficiency bonus to the hunting bird's AC, attack rolls, damage rolls, saving throws, and ability checks using Perception, Stealth, or Survival. Whenever you gain a new level in ranger, your hunting bird gains another hit die and its hit points increase by 5. When you cast a spell that targets only you, you can also target your hunting bird with the spell if the hunting bird is within 60 feet of you.

The beast obeys your commands as best as it can. It takes its turn on your initiative, though it doesn’t take an action unless you command it to. On your turn, you can verbally command the beast where to move (no action required by you). You can use your action to verbally command it to take the Attack, Dash, Disengage, Dodge, or Help action. Once you have the Extra Attack feature, you can make one weapon attack yourself when you command the beast to take the Attack action.

If you are incapacitated or absent, the beast acts on its own, focusing on protecting you and itself. The beast never requires your command to use its reaction, such as when making an opportunity attack.

While traveling through your favored terrain with only the beast, you can move stealthily at a normal pace.

Supernatural Predator

At 7th level, your connection to the magic of nature begins to seep into your hunting bird, causing it to take on supernatural abilities. The hunting bird gains the following benefits:
• The hunting bird’s natural weapons count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
• The hunting bird’s Intelligence becomes 10 if it’s not already higher, and it can understand all languages that you understand.
• While your hunting bird remains within 1 mile of you, the two of you can communicate with each other telepathically. You can use this link to issue commands instead of using words or gestures.

Falconer’s Bond

At 11th level, the magical bond between you and your hunting bird strengthens to the point that you can fight and act as one, gaining the following benefits:
• The hunting bird has advantage on attack rolls against a creature if another enemy of that creature is within 5 feet of it and that enemy isn’t incapacitated.
• You have advantage on attack rolls against a creature if your hunting bird has hit that creature with an attack this turn.

Aerial Superiority

Beginning at 15th level, your hunting bird becomes a deadly and elusive force in the sky. As long as the hunting bird is flying, it gains the following benefits:
• If the hunting bird is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
• if the hunting bird dives at least 20 feet straight toward a target and then hits it with a melee weapon attack, that attack deals an extra 3d6 damage.
