The Armorer Artificer in Dungeons & Dragons 5th Edition (D&D 5e) transforms a suit of armor into a magical extension of themselves. Whether you want to be a mystical tank or stealthy arcane operative, the Armorer gives you a customizable suit of infused armor that enhances your combat and magical abilities.

Why Play an Armorer?

Highly Customizable: Choose between Guardian (defensive melee) and Infiltrator (stealthy ranged) armor modes.

Magic & Armor Synergy: Cast spells while wearing heavy armor and use your armor as a spell focus.

Tough but Flexible: Excellent for players who want high durability without sacrificing spellcasting.

Thematic Roleplay: Be a runic knight, a stealthy arcane agent, or a steampunk-inspired inventor.

If you want a subclass that can tank, fight, sneak, or support, while looking incredibly cool, the Armorer is for you.

Core Features of the Armorer

Here are the core class features that define the Armorer:

Arcane Armor

At 3rd level, you can bond a suit of armor to yourself. It becomes impossible to remove and replaces missing limbs, integrating completely with your body. It also allows you to cast spells using the armor as your focus.

Armor Model

Choose one of two options:

• Guardian: Get Thunder Gauntlets (magical melee weapons that taunt enemies) and boost survivability.

• Infiltrator: Gain a Lightning Launcher and stealth-enhancing armor that doesn’t impose disadvantage.

Extra Attack

At level 5, you can attack twice per turn, a big boost for melee or ranged builds.

Armor Modifications

Your armor gains more infusion slots, letting you stack magical upgrades for powerful combinations.

Perfected Armor

At 15th level, Guardian mode damages enemies that hit you, and Infiltrator mode adds extra lightning damage to every hit.

Best Ability Scores for Armorers

Intelligence (Top Priority): Powers your spells and determines your subclass features.

Constitution (Very Important): Keeps you alive and helps with concentration.

Strength or Dexterity: Depending on whether you choose Guardian (Strength) or Infiltrator (Dexterity).
