Shell Caster Public

Mastering the art of infusing spells into projectiles, the shell caster uses its caster pistol to unleash a deadly array of spells. By infusing spells into shells the shell caster can do things other casters cannot, such as casting while silenced, though this does come at a cost of being less adaptable than other casters. 

Firearm Proficiency

3rd-level Shellcaster feature

You gain proficiency with Firearms and Smith's Tools. If you already have proficiency with Smith's Tools, you gain proficiency with one other type of artisan’s tools of your choice.

Caster Pistol

You can create a Caster Pistol, which is the conduit of all your casting, by spending an hour with smiths tools. If you create a new caster pistol, your previous caster pistol stops working. After Creating your pistol, with the exception of cantrips, the Shellcaster can no longer cast spells like normal. Instead after a short rest the Shellcaster gains magic shells equal to total spell slots plus half of intelligence bonus.

These shells can be infused with a spell, doing so takes one minute plus any cast time and requires all normal components at the time of the infusion, if you are not in combat you may infuse as many shells as you want with the one additional minute but you must add all of the spells cast time to the time it takes. These spells always use the highest level spell slot you can cast regardless of what spell is infused. 

After infusion you may cast these spells from your caster pistol by loading a shell. Spells cast in this manner always have a casting time of one action and no longer require any components other than pointing your pistol and pulling the trigger, concentration spells still require concentration. touch spells cast in this manner now have a range of 30ft. These spells also cast at the power when infused, so if you were to lose spell modifiers before casting you would use the stats at time of creation rather than now.

You may still cast prepared rituals as normal but may only prepare half as many rituals as you could spells.

Specialized Shells

Your work with the caster pistol has resulted in you making more specialized shells. You gain access to quick shells, adaptive shells and Impact Shells.

Quick Shells: now whenever you infuse a spell into a magic shell with a casting time of a bonus action or less they now use that cast time instead of an action.

Adaptive Shells: you gain a number of adaptive shells in addition to your normal shells equal to half your proficiency bonus rounded down. These shells can be infused with a spell using a bonus action allowing you to infuse a spell in combat.

Cantrip Shells: You may now cast cantrips from your pistol without requiring a shell. Touch range cantrips now have a range of 30 feet and all cantrips cast from your caster pistol gain bonus damage equal to your spell casting modifier. 

The Big One

9th-level Shellcaster feature

You discover how to infuse a large amount of magic into a single shell. After a long rest you gain a single big one shell. This shell can be infused with any spell from the artificer, sorcerer or wizard spell list with a spell level equal to or lower than half your artificer level rounded up. This spell still requires all components on creation, like a regular shell, but also has a cast time equal to the spell's cast time instead of just one action. The spell slot always equals half your artificer level rounded up, no matter what spell is infused.

• You gain a second Big One Shell.
