Artillerist

An Artillerist specializes in using magic to hurl energy, projectiles, and explosions on a battlefield.

Tool Proficiency

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

Artillerist Spells

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

Artificer Level	Spells
3rd	Shield, Thunderwave
5th	Scorching Ray, Shatter
9th	Fireball, Wind Wall
13th	Ice Storm, Wall of Fire
17th	Cone of Cold, Wall of Force

Eldritch Cannon

At 3rd level, you learn how to create a magical cannon. Using woodcarver's tools or smith's tools, you can take an action to magically create a Small or Tiny eldritch cannon in an unoccupied space on a horizontal surface within 5 feet of you. A Small eldritch cannon occupies its space, and a Tiny one can be held in one hand. Once you create a cannon, you can't do so again until you finish a long rest or until you expend a spell slot of 1st level or higher.
     You can have only one cannon at a time and can't create one while your cannon is present. The cannon is a magical object. Regardless of size, the cannon has an AC of 18 and a number of hit points equal to five times your artificer level. It is immune to poison damage, psychic damage, and all conditions. If it is forced to make an ability check or a saving throw, treat all its ability scores as 10 (+0). If the Mending spell is cast on it, it regains 2d6 hit points. It disappears if it is reduced to 0 hit points or after 1 hour. You can dismiss it early as an action.
     When you create the cannon, you determine its ap­pearance and whether it has legs. You also decide which type it is, choosing from the options on the Eldritch Can­nons table. On each of your turns, you can take a bonus action to cause the cannon to activate if you are within 60 feet of it. As part of the same bonus action, you can direct the cannon to walk or climb up to 15 feet to an unoccupied space, provided it has legs.

Cannon	Activation
Flamethrower	The cannon exhales fire in an adjacent 15-foot cone that you designate. Each creature in that area must make a Dexterity saving throw against your spell save DC, taking 2d8 fire damage on a failed save or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren't being worn or carried.
Force Balista	Make a ranged spell attack, originating from the cannon, at one creature or object within 120 feet of it. On a hit, the target takes 2d8 force damage, and if the target is a creature, it is pushed up to 5 feet away from the cannon.
Protector	The cannon emits a burst of positive en­ergy that grants itself and each creature of your choice within 10 feet of it a number of temporary hit points equal to 1d8 + your Intelligence modifier (minimum of +1).

Arcane Firearm

At 5th level, you know how to turn a wand, staff, or rod into an arcane firearm, a conduit for your destructive spells. When you finish a long rest, you can use wood­carver's tools to carve special sigils into a wand, staff, or rod and thereby turn it into your arcane firearm. The sigils disappear from the object if you later carve them on a different item. The sigils otherwise last indefinitely. You can use your arcane firearm as a spellcasting focus for your artificer spells. When you cast an artificer spell through the firearm, roll a d8, and you gain a bo­nus to one of the spell's damage rolls equal to the num­ber rolled.
 

Explosive Cannon

Starting at 9th level, every eldritch cannon you create is more destructive:

• The cannon's damage rolls all increase by 1d8.
• As an action, you can command the cannon to deto­nate if you are within 60 feet of it. Doing so destroys the cannon and forces each creature within 20 feet of it to make a Dexterity saving throw against your spell save DC, taking 3d8 force damage on a failed save or half as much damage on a successful one.

 

Fortified Position

Starting at 15th level, you're a master at forming well-defended emplacements using Eldritch Cannon:

• You and your allies have half cover while within 10 feet of a cannon you create with Eldritch Cannon, as a result of a shimmering field of magical protection that the cannon emits.
• You can now have two cannons at the same time. You can create two with the same action (but not the same spell slot), and you can activate both of them with the same bonus action. You determine whether the can­nons are identical to each other or different. You can't create a third cannon while you have two.
