If technology mimics nature, the Wyrmforger seeks to outfit themselves with the innate might of dragons. Not content with conventional arms, this artificer's specialized cannon harnesses the ruinous powers of the elements. Their branch of engineering is often a topic of controversy - factions employing these artificers use their very threat as a means to defend their borders or intimidate their enemies.

Tool Proficiency

You gain proficiency with smith’s tools. If you already have this proficiency, you can choose to either gain expertise instead or gain proficiency with one other type of artisan's tools of your choice.

Dragon Cannon

3rd-level Wyrmforger feature

Starting 3rd level, you can build your own weapon to replicate the might of dragons. Choose a damage type; acid, cold, fire, force, lightning, necrotic, poison, psychic, radiant, or thunder. When using the Dragon Cannon to make an attack or using Wyrm's Breath ability, you deal the damage of your chosen damage type. As a bonus action on your turn, you can change the chosen damage type. You may do so a number of times equal to your proficiency bonus and you regain all expended uses when you finish a long rest, provided you have Smith's Tools in hand. Additionally, you can use your Dragon Cannon as a spellcasting focus for your artificer spells and it counts as a weapon for your Infuse Items feature.

Dragon Cannon. You are proficient with the Dragon Cannon, it counts as a simple ranged weapon for you and has the two-handed property with a normal range of 80 feet and a long range of 320 feet. The Dragon Cannon uses your spell attack modifier for attack rolls, and spellcasting modifier for damage rolls, and deals 2d6 of your chosen damage type on a hit.
This damage increases to 2d8 at 9th level and 2d10 at 15th level.

Wyrm's Breath

3rd-level Wyrmforger feature

Also at 3rd Level, the dragon's breath weapon is one of its most feared assets. Your Dragon Cannon is engineered to unleash a replica called Wyrm's Breath.

Wyrm's Breath (Recharge 5–6). Once per turn as an action, your Dragon Cannon can shoot destructive energy in either a 30ft line that is 5ft wide or a 15ft cone. Each creature caught in the area must make a Dexterity saving throw against your spell save DC taking 2d6 damage of the Dragon Cannon's chosen damage type on a failed save, or half as much damage on a successful one.
This damage increases to 4d6 at 6th level, 8d6 at 9th level, 12d6 at 12th level, and 16d6 at 15th level. At the start of each of your turns, roll a d6. If the roll is one of the numbers in the recharge notation, you regain the use of Wyrm's Breath ability. The ability also recharges when you finish a short or long rest.

Wyrm Shell

5th-level Wyrmforger feature

At 5th level, you improve your Dragon Cannon to capture the innate magic of Dragonkind. As an action and using a spell slot of first level or higher, you can activate Wyrm Shell to enhance your Dragon Cannon for a duration of 10 minutes. During this time you can cast a cantrip specific to the element of your Dragon Cannon with your action (listed below) and add your intelligence modifier to the damage (minimum 1) (note: this doesn't stack with other class features that increase cantrip damage like Agonizing Blast).
