An alchemical bombardier is an expert at combining exotic reagents to produce a variety of materials, from healing draughts that can mend a wound in moments to clinging goo that slows creatures down.

Tool Proficiency

When you adopt this specialization at 3rd level, you gain proficiency with alchemist’s supplies. If you already have this proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

Alchemist Spells

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Alchemist Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Alchemist Spells

Artificer Level	Spell
3rd	healing word, fog cloud
5th	shatter, heat metal
9th	fireball, mass healing word
13th	blight, black tentacles
17th	cloudkill, greater restoration

Alchemist's Satchel

At 3rd level, you craft an Alchemist’s Satchel, a bag of reagents that you use to create a variety of concoctions. The bag and its contents are both magical, and this magic allows you to pull out exactly the right materials you need for your Alchemical Formula options, described below. After you use one of those options, the bag reclaims the materials. If you lose this satchel, you can create a new one over the course of an hour by converting Alchemist's Supplies.

This Alchemist's Satchel can be used as Alchemist's Supplies for any purposes including as a Spellcasting Focus for your Artificer Spells.  Despite being magical it can be infused as if it was a non magical Spellcasting Focus.

Alchemical formula

At 3rd level, you learn four Alchemical Formula options: Alchemical Fire, Alchemical Acid, and one other option of your choice. You learn an additional formula of your choice at 9th, 14th, and 17th levels.
To use any of these options, your Alchemist’s Satchel must be within reach. If an Alchemical Formula option requires a saving throw, the DC is 8 + your proficiency bonus + your Intelligence modifier.

Alchemical Acid

As an action, you can reach into your Alchemist’s Satchel, pull out a vial of acid, and hurl the vial at a creature or object within 30 feet of you (the vial and its contents disappear if you don’t hurl the vial by the end of the current turn). The vial shatters on impact. A creature must succeed on a Dexterity saving throw or take 2d6 acid damage. An object
automatically takes that damage, and the damage is maximized.

This formula’s damage increases by 1d6 when you reach certain levels in this class: 5th level (3d6), 7th level (4d6), 9th level (5d6), 11th level (6d6), 13th level (7d6), 15th level (8d6), 17th level (9d6), and 19th level (10d6).

Alchemical Fire

As an action, you can reach into your Alchemist’s Satchel, pull out a vial of volatile liquid, and hurl the vial at a creature, object, or surface within 30 feet of you (the vial and its contents disappear if you don’t hurl the vial by the end of the current turn). On impact, the vial detonates in a 5-foot radius. Any creature in that area must succeed on a Dexterity saving throw or take 1d6 fire damage.

This formula’s damage increases by 1d6 when you reach certain levels in this class: 4th level (2d6), 7th level (3d6), 10th level (4d6), 13th level (5d6), 16th level (6d6), and 19th level (7d6). 

Healing Draught

As an action, you can reach into your Alchemist’s Satchel and pull out a vial of healing liquid. A creature can drink it as an action to regain 1d8 hit points. The vial then disappears. Once a creature regains hit points from this alchemical formula, the creature can’t do so again until it finishes a long rest. If not used, the vial and its contents disappear after 1 hour. While the vial exists, you can’t use this formula.

This formula’s healing increases by 1d8 when you reach certain levels in this class: 3rd level (2d8), 5th level (3d8), 7th level (4d8), 9th level (5d8), 11th level (6d8), 13th level (7d8), 15th
level (8d8), 17th level (9d8), and 19th level (10d8).

Smoke Stick

As an action, you can reach into your Alchemist’s Satchel and pull out a stick that produces a thick plume of smoke. You can hold on to the stick or throw it to a point up to 30 feet away as part of the action used to produce it. The area in a 10-foot radius around the stick is filled with thick smoke that blocks vision, including darkvision. The stick and smoke persist for 1 minute and then disappear. After using this formula, you can’t do so again for 1 minute.

Swift Step Draught

As a bonus action, you can reach into your Alchemist’s Satchel and pull out a vial filled with a bubbling, brown liquid. As an action, a creature can drink it. Doing so increases the creature’s speed by 20 feet for 1 minute, and the vial disappears. If not used, the vial and its contents disappear after 1 minute. After using this formula, you can’t do so again for 1 minute.

Tanglefoot Bag

As an action, you can reach into your Alchemist’s Satchel and pull out a bag filled with writhing, sticky black tar and hurl it at a point on the ground within 30 feet of you (the bag and its contents disappear if you don’t hurl the bag by the end of the current turn). The bag bursts on impact and covers the ground in a 5-foot radius with sticky goo. That area becomes difficult terrain for 1 minute, and any creature that starts its turn on the ground in that area has its speed halved for that turn. After using this formula, you can’t do so again for 1 minute.

Thunderstone

As an action, you can reach into your Alchemist’s Satchel and pull out a crystalline shard and hurl it at a creature, object, or surface within 30 feet of you (the shard disappears if you don’t hurl it by the end of the current turn). The shard shatters on impact with a blast of concussive energy. Each creature within 10 feet of the point of impact must succeed on a Constitution saving throw or be knocked prone and pushed 10 feet away from that point.

Powerful Bombardier

At 5th level you have improved the power of your alchemical formulas.  Whenever you use an alchemical formula from your alchemist's satchel you add a bonus to one roll of the alchemical formula.   That roll must restore hit points or be a damage roll, and the bonus equals your Intelligence modifier (minimum of +1).

Pinpoint Bombardier

Starting at 9th level, your Alchemical Fire and Alchemical Acid now deal half damage on a successful save.

Alchemical Inured

By 15th level, you have been exposed to so many chemicals and explosions that they pose little risk to you:

• You gain resistance to acid, cold, fire, lightning, poison and thunder damage, and you are immune to the poisoned condition.
