Warforged Artificer in City Campaigns (2014 Rules)

Rules edition: This city-campaign guide uses the legacy Warforged from Eberron: Rising from the Last War and the 2014 Artificer, including the class revisions and optional choices in Tasha’s Cauldron of Everything. It does not combine these with the revised Warforged or revised Artificer in Eberron: Forge of the Artificer (2025). Use the options your DM has approved.

A Warforged Artificer fits an urban campaign where the hardest problems involve access, infrastructure, crowded streets, and competing factions. The character’s armor and tools help them survive close-quarters trouble, while Artificer spells and infusions offer practical ways to investigate a workshop, protect a neighborhood, or negotiate with a guild. The strongest build depends on which of those jobs your campaign actually asks you to do.

What the legacy Warforged traits provide

The 2019 Warforged has a fixed increase of +2 Constitution and +1 to one other ability score. Intelligence is a strong choice for an Artificer. Constructed Resilience grants advantage on saving throws against being poisoned, resistance to poison damage, and immunity to disease. Warforged do not need to eat, drink, breathe, or sleep. They still take long rests: a long rest requires at least six hours in an inactive, motionless state, during which the Warforged remains conscious and can see and hear.

Integrated Protection grants a +1 bonus to Armor Class. A Warforged can wear only armor they are proficient with; putting on or removing armor other than a shield takes one hour, and armor incorporated into the body cannot be removed against the Warforged’s will. Use the armor’s normal AC calculation, then add the Warforged’s +1. The legacy trait does not provide an unarmored 11 + Dexterity AC formula.

Specialized Design grants one skill proficiency and one tool proficiency of your choice. It does not grant a built-in tool, proficiency with that tool automatically, or advantage on checks. Pick options that add something your class and background do not already provide, such as Insight for reading a tense negotiation or calligrapher’s supplies for copying municipal records.

Ability scores and city skills

Prioritize Intelligence for Artificer spell attacks, spell save DC, and subclass features. Constitution supports hit points and concentration saves; Dexterity helps initiative and common saves. With the standard array, one simple legacy assignment is Strength 8, Dexterity 13, Constitution 14, Intelligence 15, Wisdom 12, Charisma 10. Apply the Warforged’s +2 Constitution and +1 Intelligence for Constitution 16 and Intelligence 16. Point buy can reach the same pair before choosing a background.

For city play, choose skills that match the campaign’s recurring challenges. Investigation helps search a crime scene or workshop; Perception helps spot a tail; Insight helps assess a witness; and Arcana or History can identify magical devices and local records. The 2014 Guild Artisan background grants its listed proficiencies and guild access; it does not add duplicate proficiency bonuses when you already have the same proficiency. Soldier suits a veteran whose contacts come from the watch or military. Use a background from the edition your table is playing.

Choose a specialist for the campaign’s pressure points

Battle Smith: protect people in dangerous streets

The Battle Smith’s Steel Defender adds a second body for blocking a narrow passage, helping evacuate civilians, or guarding an informant. Battle Ready lets you use Intelligence instead of Strength or Dexterity for attacks with magic weapons. The defender’s reaction can impose disadvantage on an attack against another creature within 5 feet of it, so position it beside the ally most likely to be targeted. It cannot cover an entire party at once, and it is not a substitute for planning an escape route.

Armorer: make the armor part of the story

The Armorer, introduced in Tasha’s Cauldron of Everything, is a good choice when the character’s equipment and public identity matter. Arcane Armor can be donned or removed as an action and includes the armor in the subclass features; this is separate from the Warforged’s one-hour Integrated Protection process. Guardian armor offers Defensive Field temporary hit points and Thunder Gauntlets that can discourage attacks against your allies. Infiltrator armor supports surveillance and movement. Neither model replaces the Warforged’s +1 AC.

Artillerist: defend a location or control an approach

An Artillerist’s Eldritch Cannon can be carried or placed, subject to its size and the feature’s limits. The Flamethrower affects creatures in a 15-foot cone; the Force Ballista makes its ranged spell attack at a target within 120 feet. The Protector grants temporary hit points to nearby creatures within 10 feet of the cannon. Choose the mode to match the map: a narrow alley favors the cone, while a rooftop or long street can give the ballista room to work. Only the Flamethrower requires close positioning.

Legacy infusions and useful preparations

The 2014 Artificer’s Infuse Item feature is different from the 2025 Artificer’s Replicate Magic Item feature. At Artificer level 2, the legacy class lets you learn four infusion options and maintain two infused items at once; both limits increase as you gain Artificer levels. Your DM still controls which sourcebooks are allowed and whether a particular item is available in the campaign.

Enhanced Defense: improve a suit of armor or a shield. It is a straightforward way to support a front-line Guardian or Battle Smith.
Repeating Shot: useful for a Battle Smith or ranged build that relies on a compatible weapon.
Replicate Magic Item: Bag of Holding can solve storage problems during investigations or travel, if your table allows that option.
Spell-Refueling Ring: this infusion has an Artificer level 6 prerequisite and can recover a spell slot once per day under its rules.
Ring or Cloak of Protection: these are Replicate Magic Item choices with an Artificer level 10 prerequisite, not level 6 infusions.

These are options, not a mandatory loadout. Infusions can be reassigned when the class feature permits, so ask what kinds of scenes the DM expects before committing your known options.

Spells, concentration, and action economy

Artificers prepare spells from their class list after a long rest. For a city campaign, detect magic and identify can help investigate an enchanted object; disguise self can support an infiltration if your subclass or source grants it; faerie fire can reveal invisible creatures and help allies land attacks; and web can block a doorway or slow a pursuit. Check the spell’s range and components against the scene rather than assuming a spell solves every urban obstacle.

Faerie fire, web, heat metal, and haste each require concentration, so you can maintain only one of them at a time. Heat metal deals its damage when cast and on later bonus actions while you maintain concentration; its target can use an action to make a Constitution saving throw to drop the object if it can. If the target cannot or will not drop it, it has disadvantage on attack rolls and ability checks until the start of your next turn. These details make it powerful against a metal weapon or armor, but the spell is not a universal no-save damage button.

War Caster can help maintain concentration and handle somatic components when its requirements are met. Resilient (Constitution) is another option if you want Constitution-save proficiency and the ability-score increase is useful. Choose a feat for the way your character actually fights; a Warforged’s Constitution bonus does not by itself grant proficiency or advantage on concentration saves.

Use the city as part of the build

Make a short list with the DM before play: one place your character knows well, one group that trusts them, and one institution that wants something from them. A former Cannith workshop, a district watch post, a hospital, or a newspaper office can turn tool proficiencies into scenes instead of bonuses on a character sheet. Ask which services an artisan guild offers, who can repair specialist equipment, and what the city’s laws say about visible weapons or a deployed Eldritch Cannon.

In combat, use cover and bottlenecks, but avoid putting the whole party behind one doorway where an area effect can catch everyone. The Battle Smith’s defender can guard a retreat; the Artillerist can support a fixed position; and the Armorer can draw attention while allies move civilians or secure an objective. Outside combat, let investigation, tool use, contacts, and prepared spells carry as much weight as damage. That balance is what makes this combination useful in a city campaign.

For a table using the revised rules, rebuild from the sources permitted by the DM rather than importing the legacy ability increases, Integrated Protection wording, or Infuse Item list into the newer options. The revised Artificer in Eberron: Forge of the Artificer replaces Infuse Item with Replicate Magic Item and updates the class and subclasses; its rules need their own build choices.
