The subclasses are all listed alphabetically. In the features table for each subclass, the features may be prefixed with one of the symbols above. If it isn't, no change has been made to the ability. After the four default Subclasses there is two New ones; the Archivist, and the Biomancer.

Alchemist

An Alchemist is an expert at combining reagents to produce mystical effects. Alchemists use their creations to give life and to leech it away. Alchemy is the oldest of artificer traditions, and its versatility has long been valued during times of war and peace.

Alchemist Features

Alchemist Level	Features
3rd	Tool Proficiency Alchemist Spells, (^)Experimental Elixir
5th	Alchemical Savant
9th	Restorative Reagents
15th	Chemical Mastery

Tool Proficiency

3rd-level Alchemist feature

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

3rd-level Alchemist feature

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	Spells
3rd	Healing Word, Ray of Sickness
5th	Flaming Sphere, Melf’s Acid Arrow
9th	Gaseous Form, Mass Healing Word
13th	Blight, Death Ward
17th	Cloudkill, Raise Dead

Experimental Elixir

3rd-level Alchemist feature

Whenever you finish a long rest, you can magically produce an experimental elixir in an empty flask you touch. Roll on the Experimental Elixir table for the elixir’s effect, which is triggered when someone drinks the elixir. As a bonus action, a creature can drink the elixir or as an action, administer it to an incapacitated creature.

You can create additional experimental elixirs by expending a spell slot of 1st level or higher for each one. When you do so, you use your action to create the elixir in an empty flask you touch, and you choose the elixir’s effect from the Experimental Elixir table.

Creating an experimental elixir requires you to have alchemist’s supplies on your person, and any elixir you create with this feature lasts until it is drunk or until the end of your next long rest.

When you reach certain levels in this class, you can make more elixirs at the end of a long rest: two at 6th level and three at 15th level. Roll for each elixir’s effect separately. Each elixir requires its own flask.

Experimental Elixir

d6	Effect
1	Healing. The drinker regains a number of hit points equal to 2d6 + your Intelligence modifier.
2	Swiftness. The drinker’s walking speed increases by 10 feet for 1 hour.
3	Resilience. The drinker gains a +1 bonus to AC for 1 hour.
4	Boldness. The drinker can roll a d4 and add the number rolled to every attack roll and saving throw they make for the next hour.
5	Flight. The drinker gains a flying speed of 10 feet for 1 hour.
6	Transformation. The drinker’s body is transformed as if by the alter self spell. The drinker determines the transformation caused by the spell, the effects of which last for 1 hour.

Alchemical Savant

5th-level Alchemist feature

You've developed masterful command of magical chemicals, enhancing the healing and damage you create through them. Whenever you cast a spell using your alchemist’s supplies as the spellcasting focus, you gain a bonus to one roll of the spell. That roll must restore hit points or be a damage roll that deals acid, fire, necrotic, or poison damage, and the bonus equals your Intelligence modifier (minimum of +1).

Restorative Reagents

9th-level Alchemist feature

You can incorporate restorative reagents into some of your works:

• Whenever a creature drinks for an experimental elixir you created, the creature gains temporary hit points equal to 2d6 + your Intelligence modifier (minimum of 1 temporary hit point).
• You can cast lesser restoration without expending a spell slot and without preparing the spell, provided you use alchemist’s supplies as the spellcasting focus. You can do so a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses when you finish a long rest.

Chemical Mastery

15th-level Alchemist feature

You have been exposed to so many chemicals that they pose little risk to you, and you can use them to quickly end certain ailments:

• You gain resistance to acid damage and poison damage, and you are immune to the poisoned condition.
• You can cast greater restoration and heal without expending a spell slot, without preparing the spell, and without material components, provided you use alchemist’s supplies as the spellcasting focus. Once you cast either spell with this feature, you can’t cast that spell with it again until you finish a long rest.

Armourer

An artificer who specializes as an Armorer modifies armor to function almost like a second skin. The armor is enhanced to hone the artificer’s magic, unleash potent attacks, and generate a formidable defense. The artificer bonds with this armor, becoming one with it even as they experiment with it and refine its magical capabilities.

Infiltrator

You customize your armour for subtle undertakings. It has the following features:

• Lightning Launcher. A gemlike node appears on one of your armoured fists or on the chest (your choice). It counts as a simple ranged weapon, with a normal range of 90 feet and a long range of 300 feet, and it deals 1d6 lightning damage on a hit. Once on each of your turns when you hit a creature with it, you can deal an extra 1d6 lightning damage to that target. Both the initial damage and the extra damage increases when you reach certain levels in this class, to 2d6 at 9th level and 3d6 at 15th level.

• Powered Steps. Your walking speed increases by 5 feet. Your speed increases again when you reach certain levels in this class, to 10 feet at 9th level and 15 feet at 15th level.

• Dampening Field. You have advantage on Dexterity (Stealth) checks. If the armour normally imposes disadvantage on such checks, the advantage and disadvantage cancel each other, as normal.

Extra Attack

5th-level Armourer feature

You can attack twice, rather than once, whenever you take the Attack action on your turn.

Armour Modifications

9th-level Armourer feature

You learn how to use your artificer infusions to specially modify your Arcane Armor. That armour now counts as separate items for the purposes of your Infuse Items feature: armour (the chest piece), boots, helmet, and the armour’s special weapon. Each of those items can bear one of your infusions, and the infusions transfer over if you change your armour’s model with the Armor Model feature. In addition, the maximum number of items you can infuse at once increases by 2, but those extra items must be part of your Arcane Armor.

Perfected Armour

15th-level Armourer feature

Your Arcane Armour gains additional benefits based on its model, as shown below.

Infiltrator

Any creature that takes lightning damage from your Lightning Launcher glimmers with magical light until the start of your next turn. The glimmering creature sheds dim light in a 5-foot radius, and it has disadvantage on attack rolls against you, as the light jolts it if it attacks you. In addition, the next attack roll against it has advantage, and if that attack hits, the target takes an extra 1d6 lightning damage.

Artillerist

An Artillerist specializes in using magic to hurl energy, projectiles, and explosions on a battlefield. This destructive power is valued by armies in the wars on many different worlds. And when war passes, some members of this specialization seek to build a more peaceful world by using their powers to fight the resurgence of strife. The world-hopping gnome artificer Vi has been especially vocal about making things right: “It’s about time we fixed things instead of blowing them all to hell.”

Arcane Firearm

5th-level Artillerist feature

You know how to turn a wand, staff, or rod 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 wand, staff, or rod 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.

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 the spell’s damage or healing equal to the number rolled.

Explosive Cannon

9th-level Artillerist feature

Every eldritch cannon you create is more destructive:

• The cannon’s effect rolls all increase by 1d8.
• As an action, or as a reaction when your cannon is reduced to 0 hit points, you can command the cannon to detonate if you are within 60 feet of it. Doing so destroys the cannon and forces each creature within 20 feet of it to make a Dexterity saving throw against your spell save DC, taking 5d8 force damage on a failed save or half as much damage on a successful one.

Fortified Position

15th-level Artillerist feature

You’re a master at forming well-defended emplacements using Eldritch Cannon:

• You and your allies have half cover while within 10 feet of a cannon you create with Eldritch Cannon, as a result of a shimmering field of magical protection that the cannon emits.
• You can now have two cannons at the same time. You can create two with the same action (but not the same spell slot), and you can activate both of them with the same bonus action. You determine whether the cannons are identical to each other or different. You can’t create a third cannon while you have two.
• The rolls for the effects of your eldritch cannon increase by another 1d8.

Battle Smith

Armies require protection, and someone has to put things back together if defences fail. A combination of protector and medic, a Battle Smith is an expert at defending others and repairing both material and personnel. To aid in their work, Battle Smiths are usually accompanied by a steel defender, a protective companion of their own creation. Many soldiers tell stories of nearly dying before being saved by a Battle Smith and a steel defender.

In the world of Eberron, Battle Smiths played a key role in House Cannith’s work on battle constructs and the original warforged, and after the Last War, these artificers led efforts to aid those who were injured in the war’s horrific battles.

Tool Proficiency

3rd-level Battle Smith feature

You gain proficiency with smith’s tools. If you already have this proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

Battle Smith Spells

3rd-level Battle Smith feature

You always have certain spells prepared after you reach particular levels in this class, as shown in the Battle Smith Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Battle Smith Spells

Artificer Level	Spells
3rd	Heroism, Shield
5th	Branding Smite, Warding Bond
9th	Aura of Vitality, Conjure Barrage
13th	Aura of Purity, Fire Shield
17th	Banishing Smite, Mass Cure Wounds

Battle Ready

3rd-level Battle Smith feature

Your combat training and your experiments with magic have paid off in two ways:

• You gain proficiency with martial weapons.
• When you attack with a magic weapon, you can use your Intelligence modifier, instead of Strength or Dexterity modifier, for the attack and damage rolls.

Steel Defender

3rd-level Battle Smith feature

Your tinkering has borne you a faithful companion, a steel defender. It is friendly to you and your companions, and it obeys your commands. See this creature’s game statistics in the Steel Defender stat block, which uses your proficiency bonus (PB) in several places. You determine the creature’s appearance and whether it has two legs or four; your choice has no effect on its game statistics.

In combat, the defender shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. If you are incapacitated, the defender can take any action of its choice, not just Dodge.

If the mending spell is cast on it, it regains 2d6 hit points. If it has died within the last hour, you can use your smith’s tools as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The steel defender returns to life after 1 minute with all its hit points restored.

At the end of a long rest, you can create a new steel defender if you have your smith’s tools with you. If you already have a steel defender from this feature, the first one immediately perishes. The defender also perishes if you die.

Arcane Jolt

9th-level Battle Smith feature

You've learned new ways to channel arcane energy to harm or heal. When either you hit a target with a magic weapon attack or your steel defender hits a target, you can channel magical energy through the strike to create one of the following effects:

• The target takes an extra 2d8 force damage.
• Choose one creature or object you can see within 30 feet of the target. Healing energy flows into the chosen recipient, restoring 2d8 hit points to it.

You can use this energy a number of times equal to your proficiency bonus + your Intelligence modifier (minimum of once). You regain all expended uses when you finish a long rest.

Improved Defender

*15th-level Battle Smith feature/

Your Arcane Jolt and steel defender become more powerful:

• The extra damage and the healing of your Arcane Jolt both increase to 4d8.
• Your steel defender gains a +3 bonus to Armor Class.
• Whenever your steel defender uses its Deflect Attack, the attacker takes force damage equal to 1d8 + your Intelligence modifier.

New Artificer Subclasses

Archivist

Archivists are masters of knowledge, relying not on books or tomes or scrolls, but first hand accounts from those involved. Why spend decades hunting for the truth behind an ancient stone when you can ask the stone. Archivists have perfected the art of creating Artificial minds inside ordinary objects.

Shielded Mind

9th-level Archivist feature

Your mind becomes strong enough to defend against many assaults against it. You gain the following benefits:

• Psychic Defence. You gain resistance to psychic damage.
• Intrusion Protection. You have advantage on saving throws against being charmed, frightened or effects that would read your thoughts.

Psionic Expertise

15th-level Archivist feature

You can manipulate your Artificial mind to grant more than just information:

• Infoportation. As an action while your Artificial Mind is on your person, you can teleport yourself and your belongings to the nearest unoccupied space to a creature carrying one of your artificer infusions as long as you are on the same plane of existence. When you do so you can bring along a number of creatures and their belongings within 5 feet of you equal to your Intelligence modifier. You can teleport this way once and must finish a long rest before doing so again, unless you expend a spell slot of 3rd or higher to do so.
• Psionic Barrier. When you deal psychic damage to creature, you may choose to gain temporary hit points equal to the damage dealt. You can do this a number of times equal to your Intelligence modifier (minimum of once), and regain all expended uses when you finish a long rest.

Biomancer

Biomancers are artificers who have turned their skills to self-improvement in the most literal sense, reshaping their own bodies, or the bodies of others to grant powerful atypical augmentations. Most still view this craft as unnatural, especially those of faith who see it as nothing more that tarnishing the God's creations; because of this many biomancers are outcast from society, or live a life in secret for fear of public outrage. That being said, in times of war, some kingdoms have been known to employ the help of these mad scientists to create legions of super solders to give them an edge in battle.

Potent Augmentations

5th-level Biomancer feature

Your Augmentations grant additional benefits for creatures. Any creature that has at least one Augmentation gains the following benefits:

• Ability Score Improvement. One of the creatures ability scores of your choice increases by 2, to a maximum of 20.
• Learned. The creature gains proficiency in one skill of your choice.
• Regenerative. When the creature rolls a hit dice to regain hit points, it can add your Intelligence modifier to the amount healed.
• Toughened. The creatures maximum hit points increase by 1 for each hit die that they have.

Additional Augmentations

9th-level Biomancer feature

When you augment yourself or another creature, you can choose from the following additional options:

Master of Modification

15th-level Biomancer feature

You have mastered control over your own genetic code. You can choose 3 augmentations and gain their effects permanently.
