Bonus Proficiencies

When you choose this field of study at 3rd level, you gain proficiency with heavy armor, shields, and martial weapons.

Affect Armor

Also at 3rd level, if an Affect-Engine is attached to your armor and a creature within 5 feet of you hits you with a melee weapon attack, it takes 1d4 + your Intelligence modifier damage (of the Affect-Engine’s type). Your Affect Armor die changes when you have more Affect-Engines attached. The die becomes 1d6 for 2 Affect-Engines, 1d8 for 3 Affect-Engines, and 1d10 for 4 Affect-Engines. When multiple AffectEngines are attached to your armor, you choose the type of damage.

Additionally, while an Affect-Engine is attached in this way, you can use Affect Discharge through a melee weapon you are wielding that normally requires an Affect-Engine to be attached to the weapon.

When you reach 15th level in this class, your Affect Armor deals one extra die of damage.

Armor Engine Upgrade

Starting at 7th level, depending on the type of Affect Engine attached to your armor, you can use a bonus action to activate a corresponding feature that lasts for up to 1 minute. You can only use one of these options at a time. Once you use this feature, you can’t use it again until you finish a short or long rest.

Cold. At the start of each of your turns a 20-footradius around you becomes coated in slippery ice, turning the area into difficult terrain. Creatures that start their turn on the ice must make a Dexterity saving throw against your spell save DC or fall prone.

Your walking speed increases by 10 feet while moving on the slippery ice and you do not treat it as difficult terrain.

Flame. You gain a fly speed of 20 feet.

Lightning. As an action you can magnetize objects you are holding in your hand, or attract and repel magnetized objects and ferrous metals up to a distance of 60 feet. Worn objects and objects that weigh more than 30 pounds are unaffected. If held by a creature, the creature must make a Strength saving throw against your spell save DC, losing grip of the object on a failed save. You can make ranged weapon attacks with objects you are attracting or repelling, using your spell attack bonus and dealing 1d6 + your Intelligence modifier damage (of a type determined by the item).

Affect Armor Coat

At 10th level, when one or more Affect-Engines are attached to armor you are wearing, you gain a +1 bonus to AC and you have resistance to each Affect Engine’s damage type.

Affect Armor Pocket

Also at 10th level, you can store one suit of armor inside of an Affect-Engine by speaking a command word and attaching it to the armor. After 1 minute, the armor finishes collapsing into the Affect-Engine.

As an action, you can attach the Affect-Engine to a willing or unconscious creature and speak the command word. The creature gains the paralyzed condition until the start of its next turn when it is wearing the suit of armor. You can use an action to touch the Affect-Engine and speak the command word to retract the suit of armor. At the start of the creature’s next turn, the armor retracts into the Affect-Engine. This feature has no effect on creatures unable to fit a stored suit of armor and creatures already wearing medium or heavy armor.

Engine Exoskeleton

At 20th level, as an action you can combine one Affect-Engine of each type and attach them to armor you are wearing to create your ultimate armor. For the next minute, you gain the following benefits:

  • You gain resistance to all damage types except psychic.
  • Your Affect Armor deals an extra die of damage.
  • Your Affect Discharges deal an extra 3d6 damage.
  • Your Armor Engine Upgrade activates and you can swap between Armor Engine Upgrade options as a bonus action.
  • You can make a single melee weapon attack as a bonus action on each of your turns.

Once you use this feature, you can’t use it again until you finish a long rest.
