Iron Rider

Being an iron rider is more than a profession; it's a calling. Its siren song is heard in the roar of an engine, the howl of the wind, and the screaming of your blood. Using your technological know-how, you have constructed a vehicle unlike any other, one that isn't just transport, but a companion. Many of these vehicles talk, providing advice and company, and all of them can act under their own will. An iron rider's engine is an invention, yes, but it is also a partner. Together, they perform daring feats of speed, dangerous stunts that risk it all

Tool Proficiency

When you adopt this specialization at 3rd level, you gain proficiency with smith's tools. If you already have this proficiency, you gain proficiency with one other type of artisan's tools of your choice.

Iron Rider Spells

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Iron Rider Spells table. These spells counts as artificer spells for you, but they don't count against the number of artificer spells you prepare.

	Iron Rider Spells
Artificer Level	Spells
3rd	jump, longstrider
5th	blur, spider climb
9th	fly, haste
13th	freedom of movement, resilient sphere
17th	passwall, wall of stone

Iron Engine

Starting at 3rd level, you gain proficiency in vehicles (land), and your proficiency bonus is doubled for any ability check you make with them.
Also, your area of expertise has lead you to a crucial breakthrough: a personal automated vehicle, in the form of your iron engine. The iron engine is friendly to you and your companions, and it obeys your commands. See this creature's game statistics in the iron engine stat block. You determine the iron engine's appearance, and how many wheels it has; your choice has no effect on its game statistics.
In combat, the iron engine shares your initiative count, and takes its turn concurrently with yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take one of the actions in its stat block or the Dash, Disengage, Help, Hide, or Search action. Mounting or dismounting the iron engine costs you only 5 feet of movement.
If the mending spell is cast on it, it regains 2d6 hit points. If it has died within the last hour, you can use your smith's tools as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The iron engine returns to life after 1 minute with all its hit points restored.
At the end of a long rest, you can create a new iron engine if you have your smith's tools with you. If you already have an iron engine from this feature, the first one immediately perishes.

Countermeasures

Beginning at 5th level, when a creature would touch your engine or a creature riding it, or hit it or its rider with a melee attack, the engine can use its reaction to violently shock the assailant. The creature takes 1d8 lightning damage, and if it takes any of this damage it must succeed on a Constitution saving throw against your spell save DC or be unable to take reactions until the start of its next turn.

Ex Machina

At 9th level, you and your iron engine can become one. While you are within 30 feet of your iron engine, you can communicate with it telepathically, see and hear through its senses as well as your own, and cast spells through it as if you were in its space. Also, while you are mounted on your iron engine, you can make any spell you cast that targets only you also target your engine.

Road Warrior

  Starting at 15th level, your innovation knows no bounds. Your iron engine gains the following benefits:

• It gains a +2 bonus to its Armor Class.
• It has resistance to nonmagical bludgeoning, piercing, and slashing damage.
• If it moves at least half its speed towards a creature before hitting it with a Slam attack, the attack deals an extra 2d6 damage and pushes a Large or smaller creature up to 10 feet away.
