Many adventurers rely on weapons they find. Swords of bountiful flames. Staves that conjure blizzards. Bows with unlimited projectiles. Scrolls allowing one to cast a spell effortlessly. An Armorer relies on no such thing. They instead rely on their own specially crafted weapons, directly integrated into their own armor. Thunderous punches, streaks of lightning... but not all Armorers have relied on those same two weapons.

An Armorer's armor is an extension of themself. A reflection. Not all armorers use the same model of armor. Many seek greater power. They wish to test the limits of their own artifice capabilities. Some seek to learn from the masters before them. Others wish to design their own works of art. The standard Guardian and Infiltrator, as impressive and easy to master as they are, are only a starting point in some Armorers' eyes. There is always room for improvement and creativity.

An interesting result of this personalization is that no two models of Power Armor are designed quite the same way. One's Guardian model may be inscribed into their armor a bit differently from another's. However, the underlying designs for any model are essentially the same, and if one Armorer were to learn the secrets of a new model, those secrets could be passed down in the form of an Armor Model Blueprint.

 

Artificer Armor Model Blueprints

Armor Model Blueprints are designed to be replacements for magical weapons for an Armorer Artificer player, for them to discover and incorporate into their armor. New and unique options they may choose instead of the default Guardian and Infiltrator models, allowing for significantly more personalization and variety when playing the subclass. These new armor models cannot normally be immediately integrated into the suit, but instead are studied by the player and crafted over the course of the player's downtime. Alternatively, another powerful artificer may be able to craft it for them after studying the player's Power Armor if downtime is not part of your campaign.

You may not normally select these armor models by default. Instead, you may add one of these armor model options to your Armor Model feature by finding its respective blueprint. Once you have a blueprint, you must then create an armor disc, an item that contains information to change your armor model, by following the downtime activity rules for crafting a magic item as detailed in the Dungeon Master's Guide. The normal time and cost are both cut in half, however. Common and uncommon blueprints are also affected by your Magic Item Master feat in addition.

An armor disc, once created, appears as a tiny platinum disc-shaped object that is highly reflective and inscribed with magic runes. The disc has 8 AC and 6 HP, and weighs 1/10th lb. If one of these discs is somehow damaged, it cannot be installed again until it is repaired, and takes 4 hours of work to repair. You may split this time across two short rests, and having the Mending cantrip halves the time, allowing you to repair a disc in one short rest.

Once you have an armor model disc, you may replace one of your available armor models detailed in your Armor Model feature to the disc's respective armor model during a long rest, with the replaced armor model appearing as its own respective armor disc and being unavailable from your Armor Model feature until reinstalled, and the new armor model becoming available from your Armor Model feature in its place. You may only switch between the two active models after a short rest. At 15th level, as part of your Perfected Armor feature, you also gain the ability to switch two of your armor discs on a long rest instead of one.

How you obtain armor model blueprints is up to your DM. You may find them as dungeon loot in dungeons where constructs or artifice magic are common. They may be gifted to you as rewards for quests from a powerful artificer. Perhaps they are secret knowledge hidden away by an old master in the most obscure of places. Alternatively, your DM may allow you to create blueprints as detailed below. Optionally, your DM may also allow you to replace one or both of your Guardian and Infiltrator armor models with one common or uncommon armor model.

Optional: Creating a Blueprint - As an artificer, your DM may allow you to use the Research downtime activity, as detailed in Xanathar's Guide to Everything, to instead craft armor model blueprints. The usual research outcomes are replaced with these: On a 1 to 5, your research has no effect. On a 6 to 10, you create a common blueprint. On a 11 to 18, you create an uncommon or common blueprint. On a 19 to 25, you create one rare or uncommon, or two common blueprints. On a 26 to 30, you create one very rare or rare, or two common or uncommon blueprints. On a 31+, you create one legendary or very rare, two rare or uncommon, or three common blueprints.

You have access to a new infusion once you possess an armor disc.

Disc Drive.
Prerequisite: 10th level Artificer.
Item: a suit of armor.

A creature wearing a suit of armor with this infusion may install an armor disc over a long rest. The creature wearing the armor gains the benefits of the armor disc's respective armor model if it has no other armor model to choose from, or may choose it in addition to its available armor models and gain its benefits instead.

At 15th level, as part of your Perfected Armor feature, your Arcane Armor gains additional benefits for the Cryogen model. When a creature fails the save against your Cold Jets, the slow effect increases by another 5 ft. and resets the time until it wears off if it is already slowed. A creature whose speed is reduced to 0 by this attack has disadvantage on this save and on its attack rolls. In addition, you may reduce the cold immunity of one creature that otherwise would have been affected by the weapon to resistance a number of times per long rest equal to your proficiency bonus.

It cannot be healed except by Mending, and when killed, the armor breaks unless infused. It does not act on its own initiative, but can make saving throws, and you may move it with your bonus action. As long as both your own Power Armor helmet and the Echo Armor's helmet are both deployed, you and your Echo Armor cannot be immediately distinguished. If you speak or cast a spell, any creature that sees you do so can make a Wisdom (Perception) check with a DC of 10 plus your Charisma bonus plus your proficiency modifier to realize which armor you are in. You have disadvantage on the roll if the armor is a different type from your own. Your Echo Armor becomes normal armor again when you take an action to dismiss the Animation Field, or when you switch armor models.

At 15th level, as part of your Perfected Armor feature, your Arcane Armor gains additional benefits for the Echo model. You no longer lose your own senses when using Echo Sense, can sense by touch, and as long as your Echo Armor's helmet is retracted, you can smell and speak through it. Its Blindsight also extends to 120 ft and gains additional HP equal to 5 times your Intelligence modifier. You may now also have your Echo Armor attack as many times as you attack within your turn, and you can cast spells with a range of touch through your armor, which does not allow creatures to realize which armor you are in.

When attacking with these weapons, you have advantage on your attack roll and cannot receive disadvantage on the attack roll. Your target also cannot be changed except by your own effect.

• Precision Boost. Once per long rest, if an effect would give you advantage, you may roll an extra advantage die.
• Redirection Field. Whenever a non-spell ranged attack is made against you, you may impose disadvantage on the roll. You may use this ability a number of times equal to your proficiency modifier.

At 15th level, as part of your Perfected Armor feature, your Arcane Armor gains additional benefits for the Truestriker model. You may now use Precision Boost a number of times equal to your proficiency bonus, once per turn.

Crafting Armor Model Discs

Once obtaining an armor model blueprint, the disc must be crafted before it can be installed. Much the same as other magic items, the cost to craft the disc does not cover materials. Each has some sort of material component necessary for the magic that is infused into the disc, consumed by the crafting process. Your DM may allow substitutions for ingredients depending on what best fits their campaign, but should be about as difficult to obtain.
