Demolitionist

A gnome fiddles with a spherical object in her hands, while the rest of her party looks at her impatiently. She holds up one finger, then adjusts one last thing. She grins and leaps up, rushing over to a street corner where their enemy will pass soon. She sets it down and hides behind a corner, looking at where the bomb is planted. Her friends look at her expectantly. She nods and holds up three fingers, then peeks around the corner. Their rival is approaching it. She puts down one finger. They don't notice the bomb sitting there. She puts down one more. They walk right past the bomb. A maniacal grin comes across her face and puts down the last finger. She presses a button on her remote control and the bomb explodes. Their target didn't stand a chance.

Demolitionists are artificers who use their talents to make explosives. They were often used in the Last War as distractions or crowd control, lobbing bombs into large groups of people to take them out all at once. Not all demolitionists are mad bombers, though- some use stealth to take down targets from afar, or even just use them as a distraction to get the upper hand. They always know the best way to use their explosives, as they can be very versatile and useful in many scenarios.

When making the bombs, make a check using your Alchemist's supplies and divide the result by two, that’s how many bombs you make. You can also expend spell slots to craft additional bombs equal to the spell's level. You can make any number of each bomb listed in the table below: (Each bomb has a range of 30/60 but increased to 60/120 at 9th level)

Smoke Bomb: As an action, you can thrown weapon attack. Any creatures that are in a 20-foot radius of the bomb when you throw it must make a Constitution saving throw. On a failed save, they are blinded for 1 minute. The bomb also emits smoke in a 10-foot radius, making it heavily obscured. A strong wind can blow the smoke away in 1 round. The smoke lasts for 1 minute.

Each creature within 10 feet must succeed on a DC 15 Dexterity saving throw or be restrained by sticky white webs. A creature can try to free itself or another creature within its reach from the webs, doing so with a successful DC 20 Strength check. A gallon of alcohol dissolves the webs produced by a single tangler grenade. Otherwise, the webs dissolve on their own after 1 hour, freeing any creatures restrained by them.

Poison Bomb: (Prerequisite 9th-level Artificer) As an action, you can make a thrown weapon attack. All creatures within a 10ft radius of your target location must succeed on a Constitution saving throw or take 2d4 plus your Intelligence modifier poison damage and be poisoned for 1 minute.

Anti Magic Pulse: (Prerequisite 9th-level Artificer) As an action, you make a thrown weapon attack. This area is divorced from the magical energy that suffuses the multiverse for 1 hour. Within the 10ft radius, spells can’t be cast, summoned creatures disappear, and even magic items become mundane. Spells and other magical effects, except those created by an artifact or a deity, are suppressed in the area and can’t protrude into it. While an effect is suppressed, it doesn’t function, but the time it spends suppressed counts against its duration. Spells and magical effects such as dispel magic have no effect on the sphere. Likewise, the spheres created by different antimagic field spells don’t nullify each other. (Using the effect for the Antimagic Field spell)

Arcane Bomb Launcher

You know how to craft a custom bomb launching gauntlet 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 grenade launcher 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. Additionally, the range of your bombs is doubled. 

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.

Along with this when throwing a bomb, you can choose a number of creatures equal to half your intelligence mod rounded down (minimum of 1) to be unaffected by your bombs.
