a recreation of the artillerist class in a way which me my friends and most likely others will enjoy that includes many different cannon types and not the boring usual 3.

Tool Proficiency

3rd-level Artillerist feature

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

3rd-level Artillerist feature

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.

Artillerist Spells

Artificer Level	Spell
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 invention

3rd-level Artillerist feature

You've learned how to create a magical invention. Using woodcarver’s tools or smith’s tools, you can take an action to magically create a Small or Tiny eldritch invention in an unoccupied space on a horizontal surface within 5 feet of you, or you may choose to throw it placing it in a unoccupied space on a horizontal surface within 20 feet of you, but as a drawback the invention takes your artificer level in damage. A Small eldritch invention occupies its space, and a Tiny one can be held in one hand or attached to the body in some way.

Once you create a invention, you can’t do so again until you finish a long rest. You can have only one invention at a time and can’t create one while your invention is present.

The invention is a magical object. Regardless of size, the invention has an AC of 18 and a number of hit points equal to five times your artificer level if said stats are unstated. It is immune to poison damage and psychic damage. 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 8 hours. You can dismiss it early as an action.

When you create the invention, you determine its appearance and whether it has legs. You also decide which type it is, choosing from the chosen options from the Eldritch inventions list. On each of your turns, you can take a bonus action to cause the invention to activate. 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 and the cannon states no other movement speed to use.
