Subclass Progression

Level 3: Artillerist

Wield Destructive Power from Afar

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

Tools of the Trade

You gain the following benefits.

Ranged Weaponry

You gain proficiency with Martial Ranged weapons.

Tool Proficiency

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.

Wand Crafting

When you craft a magic Wand, the amount of time required to craft it is halved.

Artillerist Spells

When you reach an Artificer level specified in the Artillerist Spells table, you thereafter always have the listed spells prepared.

Artillerist Spells

Eldritch Cannon

Using Smith's Tools or Woodcarver's Tools, you can take a Magic action to create a Small or Tiny Eldritch Cannon in an unoccupied space on a horizontal surface within 5 feet of yourself. You determine its appearance, including whether you carry it or not (and your choice of legs or wheels, for the latter). It disappears if it is reduced to 0 Hit Points or after 1 hour. You can dismiss it early as a Magic action.

Once you create a cannon, you can't do so again until you finish a Long Rest or expend a spell slot to create one. You can have only one cannon at a time and can't create one while you already have one.

Level 5: Arcane Firearm

When you finish a Long Rest, you can use Woodcarver's Tools to carve special sigils into a Rod, Staff, Wand, or Martial Ranged weapon 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 1d8, and you gain a bonus to one of the spell's damage rolls equal to the number rolled.

Level 9: Explosive Cannon

Every Eldritch Cannon you create is now more destructive. You gain the following benefits.

Detonate

When your cannon takes damage, you can take a Reaction to 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 3d10 Force damage on a failed save or half as much damage on a successful one.

Firepower

The cannon's damage rolls and the number of Temporary Hit Points granted by Protector increase by 1d8.

Level 15: Fortified Position

You're a master at forming well-defended emplacements using your Eldritch Cannon. You gain the following benefits.

Double Firepower. You can now have two cannons at the same time, and you can create two with the same Magic action. (If you expend a spell slot to create the first cannon, you must expend another spell slot to create the second.) You can activate both of them with the same Bonus Action, ordering them to use the same activation option or different ones. You can't create a third cannon while you have two.

Shimmering Field Projection

You and your allies have Cover while within 10 feet of your Eldritch Cannon.
