Arcane Science

In the world of Eberron, arcane magic has been harnessed as a form of science and deployed throughout society. Artificers reflect this development. Their knowledge of magical devices, and their ability to infuse mundane items with magic, allows Eberron's most miraculous projects to continue.

During the Last War, artificers were marshaled on a massive scale. Many lives were saved because of the inventions of brave artificers, but countless lives were also lost because of the mass destruction unleashed by their creations.

Seekers of New Lore

Nothing excites a n artificer quite like uncovering a new metal or discovering a source of elemental energy. In artificer circles, new inventions and strange discoveries create the most excitement. Artificers who wish to make their mark must innovate, creating something fresh, rather than iterating on familiar designs.

This drive for novelty pushes artificers to become adventurers. Eberron's main travel routes and populated regions have long since been explored. Thus, artificers seek the frontiers of civilization in hopes of making the next great discovery in arcane research.

Creating an Artificer

When creating a n artificer, think about your character's relationship with the artisan who taught them their craft. Does the character have a rival? Talk to your DM about the role played by artificers in the campaign and the sort of organizations you might have ties to.

Class Features

As an Artificer, you gain the following class features

Tools Required

You produce your artificer spell effects through your tools. You must have a spellcasting focus-specifically thieves' tools or some kind of artisan's tool in-hand when you cast any spell with this Spellcasting feature. You must be proficient with the tool to use it in this way. See chapter 5, "Equipment," in the Player's Handbook for descriptions of these tools.

After you gain the Infuse Item feature at 2nd level, you can also use any item bearing one of your infusions as a spellcasting focus.

Cantrips

At 1st level, you know either the Prestidigitation or Mending cantrip and two additional cantrips of your choice from the artificer spell list. At higher levels, you learn additional artificer cantrips of your choice, as shown in the Cantrips Known column of the Artificer table.

Cantrip Versatility

When you gain a level in this class, you can replace one of the artificer cantrips you know with another cantrip from the artificer spell list.

Preparing and Casting Spells

The Artificer table shows how many spell slots you have to cast your artificer spells. To cast one of your artificer spells of 1st level or higher, you must expend a slot of the spell's level or higher. You regain all expended spell slots when you finish a long rest.

You prepare the list of artificer spells that are available for you to cast, choosing from the artificer spell list. When you do so, choose a number of artificer spells equal to your Intelligence modifier + half your artificer level, rounded down (minimum of one spell). The spells must be of a level for which you have spell slots.

For example, if you are a 5th-level artificer, you have four 1st-level and two 2nd-level spell slots. With an Intelligence of 14, your list of prepared spells can include four spells of 1st or 2nd level, in any combination. If you prepare the 1 st-level spell cure wounds, you can cast it using a 1st-level or a 2nd-level slot. Casting the spell doesn't remove it from your list of prepared spells.

You can change your list of prepared spells when you finish a long rest. Preparing a new list of artificer spells requires time spent tinkering with your spellcasting focuses: at least 1 minute per spell level for each spell on your list.

Spellcasting Ability

Intelligence is your spellcasting ability for your artificer spells; your understanding of the theory behind magic allows you to wield these spells with superior skill. You use your Intelligence whenever an artificer spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for an artificer spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Ritual Casting

You can cast an artificer spell as a ritual if that spell has the ritual tag and you have the spell prepared.

The Magic of Artifice As an artificer, you use tools when you cast you rspells. When describing your spellcasting, think about how you're using a tool to perform the spell effect. If you cast Cure Wounds using alchemist's supplies, you could be quickly producing a salve. If you cast it using tinker's tools, you might have a miniature mechanical spider that binds wounds. When you cast Poison Spray, you could fling foul chemicals or use a wand that spits venom. The effect of the spell is the same as for a spellcaster of any other class, but your method of spellcasting is special.

The same principle applies when you prepare your spells. As an artificer, you don't study a spellbook or pray to prepare your spells. Instead, you work with your tools and create the specialized items you'll use to produce your effects. If you replace Cure Wounds with Heat Metal, you might be altering the device you use to heal - perhaps modifying a tool so that it channels heat instead of healing energy.

Such details don't limit you in any way or provide you with any benefit beyond the spell's effects. You don't have to justify how you're using tools to cast a spell. But describing your spellcasting creatively is a fun way to distinguish yourself from other spellcasters.

Infusions Known

When you gain this feature, pick four artificer infusions to learn, choosing from the "Artificer Infusions" section at the end of the class's description. You learn additional infusions of your choice when you reach certain levels in this class, as shown in the Infusions Known column of the Artificer table.

Whenever you gain a level in this class, you can replace one of the artificer infusions you learned with a new one.

Infusing an Item

Whenever you finish a long rest, you can touch a nonmagical object and imbue it with one of your artificer infusions, turning it into a magic item. An infusion works on only certain kinds of objects, as specified in the infusion's description. If the item requires attunement, you can attune yourself to it the instant you infuse the item. If you decide to attune to the item later, you must do so using the normal process for attunement (see "Attunement" in chapter 7 of the Dungeon Master's Guide).

Your infusion remains in an item indefinitely, but when you die, the infusion vanishes after a number of days have passed equal to your Intelligence modifier (minimum of 1 day). The infusion also vanishes if you give up your knowledge of the infusion for another one.

You can infuse more than one nonmagical object at the end of a long rest; the maximum number of objects appears in the Infused Items column of the Artificer table. You must touch each of the objects, and each of your infusions can be in only one object at a time. Moreover, no object can bear more than one of your infusions at a time. If you try to exceed your maximum number of infusions, the oldest infusion immediately ends, and then the new infusion applies.

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.

Artillerist Features

Tool Proficiency

When you adopt this specialization at 3rd level, 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

Starting at 3rd level, 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.

Eldritch Cannon

At 3rd level, you learn how to create a magical cannon. Using woodcarver's tools or smith's tools, you can take an action to magically create a Small or Tiny eldritch cannon in an unoccupied space on a horizontal surface within 5 feet of you. A Small eldritch cannon occupies its space, and a Tiny one can be held in one hand.

Once you create a cannon, you can't do so again until you finish a long rest or until you expend a spell slot of 1st level or higher. You can have only one cannon at a time and can't create one while your cannon is present.

The cannon is a magical object. Regardless of size, the cannon has an AC of 18 and a number of hit points equal to five times your artificer level. It is immune to poison damage, psychic damage, and all conditions. If it is forced to make an ability check or a saving throw, treat all its ability scores as 10 (+O). 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 1 hour. You can dismiss it early as an action.

When you create the cannon, you determine its appearance and whether it has legs. You also decide which type it is, choosing from the options on the Eldritch Cannons table. On each of your turns, you can take a bonus action to cause the cannon to activate if you are within 60 feet of it. 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.

Battle Smith Features

Tool Proficiency

When you adopt this specialization at 3rd level, 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

Starting at 3rd level, 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 Ready

When you reach 3rd level, 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.

Vigilant. The defender can't be surprised.

Actions (Requires Your Bonus Action)

Force-Empowered Rend. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 1d8 + 2 force damage

Repair (3/Day). The magical mechanisms inside the defender restore 2d8 + 2 hit points to itself or to one other construct or object within 5 feet of it.

Reactions

Deflect Attack. The defender imposes disadvantage on the attack roll of one creature it can see that is within 5 feet of it, provided the attack roll is against a creature other than the defender.

Boots of the Winding Path

Prerequisite: 6th-level artificer

Item: A pair of boots (requires attunement)

While wearing these boots, a creature can teleport up to 15 feet as a bonus action to an unoccupied space the creature can see. The creature must have occupied that space at some point during the current turn.

Enhanced Arcane Focus

Item: A rod, staff, or wand (requires attunement)

While holding this item, a creature gains a +1 bonus to spell attack rolls. In addition, the creature ignores half cover when making a spell attack.

The bonus increases to +2 when you reach 10th level in this class.

Enhanced Defense

Item: A suit of armor or a shield

A creature gains a + 1 bonus to Armor Class while wearing (armor) or wielding (shield) the infused item.

The bonus increases to +2 when you reach 10th level in this class.

Enhanced Weapon

Item: A simple or martial weapon

This magic weapon grants a + 1 bonus to attack and damage rolls made with it.

The bonus increases to +2 when you reach 10th level in this class.

Homunculus Servant

Prerequisite: 6th-level artificer

Item: A gem worth at least 100 gp or a dragonshard

You learn intricate methods for magically creating a special homunculus that serves you. The item you infuse serves as the creature's heart, around which the creature's body instantly forms.

You determine the homunculus's appearance. Some artificers prefer mechanical-looking birds, whereas some like winged vials or miniature, animate cauldrons.

The homunculus is friendly to you and your companions, and it obeys your commands. See this creature's game statistics in the Homunculus Servant stat block.

In combat, the homunculus 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 the action in its stat block or the Dash, Disengage, Help, Hide, or Search action.

The homunculus regains 2d6 hit points if the mending spell is cast on it. If it dies, it vanishes, leaving its heart in its space.

Radiant Weapon

Prerequisite: 6th-level artificer

Item: A simple or martial weapon (requires attunement)

This magic weapon grants a + 1 bonus to attack and damage rolls made with it. While holding it, the wielder can take a bonus action to cause it to shed bright light in a 30-foot radius and dim light for an additional 30 feet.

The wielder can extinguish the light as a bonus action.

The weapon has 4 charges. As a reaction immediately after being hit by an attack, the wielder can expend 1 charge and cause the attacker to be blinded until the end of the attacker's next turn, unless the attacker succeeds on a Constitution saving throw against your spell save DC. The weapon regains 1d4 expended charges daily at dawn.

Repeating Shot

Item: A simple or martial weapon with the ammunition property (requires attunement)

This magic weapon grants a + 1 bonus to attack and damage rolls made with it when it's used to make a ranged attack, and it ignores the loading property if it has it.

If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you make a ranged attack with it. The ammunition created by the weapon vanishes the instant after it hits or misses a target.

Arcane Propulsion Arm

Wondrous item, very rare (requires attunement by a creature missing a hand or an arm) This prosthetic appendage was developed by artificers of House Cannith. To attune to this item, you must attach it to your arm at the wrist, elbow, or shoulder, at which point the prosthetic magically forms a copy of the appendage it's replacing.

While attached, the prosthetic provides these benefits:

• The prosthetic is a fully capable part of your body.
• You can take an action to remove the prosthetic, and it removes itself if your attunement to it ends. It can't be8removed against your will.
• The prosthetic is a magic melee weapon with which you're proficient. It deals 1d8 force damage on a hit and has the thrown property, with a normal range of 20 feet and a long range of 60 feet. When thrown, the prosthetic detaches and flies at the target of the attack, then immediately returns to you and reattaches.

Armblade

Weapon (any one-handed melee weapon), common (requires attunement by a warforged) An armblade is a magic weapon that attaches to your arm, becoming inseparable from you as long as you're attuned to it. To attune to this item, you must hold it against your forearm for the entire attunement period.

As a bonus action, you can retract the armblade into your forearm or extend it from there. While it is extended, you can use the weapon as if you were holding it, and you can't use that hand for other purposes.

Ventilating Lungs

Wondrous item, rare (requires attunement) These metallic nodules were created in response to the poisonous gases used on the battlefields of the Last War. When you attune to these lungs, they replace the lungs in your chest, which disappear. The lungs allow you to breathe normally, even in an antimagic field, and their breathing function can't be suppressed by magic.

Outside an antimagic field or any other effect that suppresses magic, these lungs allow you to breathe normally in any environment (including a vacuum), and you have advantage on saving throws against harmful gases such as those created by a Cloudkill spell, a Stinking Cloud spell, inhaled poisons, and gaseous breath weapons .

As an action, you can use these lungs to exhale a gust of wind, as if you had cast the Gust of Wind spell (spell save DC 15) with no components. This property of the lungs can't be used again until the next dawn.

If your attunement to the lungs ends, your original lungs reappear.

Wand Sheath

Wondrous item, common (requires attunement by a warforged) A wand sheath clamps onto your arm and imparts the following benefits:

• The wand sheath can't be removed from you while you're attuned to it.
• You can insert a wand into the sheath as an action. The sheath can hold only one wand at a time .
• You can retract or extend a wand from the sheath as a bonus action. While the wand is extended, you can use it as if you were holding it, but your hand remains free.

If a sheathed wand requires attunement, you must attune to the wand before you can use it. However, the wand sheath and the attached wand count as a single magic item with regard to the number of magic items you can attune to. If you remove the wand from the sheath, your attunement to the wand ends.
