Path of Iron Gears

It is a warrior’s duty to perish in the glory of the battlefield. Some, however, are not granted such an honor, their broken bodies left behind in the march of progress. It would be a waste to allow such spirits to languish, their honed instincts left wanting by mortal limitations. The flesh is weak; cast it aside. Only the perfection of steel will grant the strength to rend the empire’s enemies asunder.

Biomechanical Upgrades

Your body has been augmented with mechanical upgrades, allowing you to transcend the limits of the flesh. You gain a number of the following Biomechanical Upgrades equal to your Rage Damage bonus. These Biomechanical Upgrades cannot be unwillingly removed while you live; however, you can exchange one choice of Biomechanical Upgrade for another when you gain a level in this class.

Extended Grip

When you make a melee weapon attack, you can give the weapon or unarmed strike the Reach property.

Molten Core

The heat that rises from your body is weaponized to burn attackers with steam. When a creature within 5 feet deals damage to you, you can use your reaction to deal damage to it equal to your Strength modifier. While you are raging, this damage is increased by your Rage Damage bonus.

Organometallic Fascia

Armor is interwoven into your very flesh, rendering it inseparable from your being. You gain proficiency in heavy armor. In addition, over the course of a long rest, you can integrate a suit of armor into your body, granting you its AC, though you still count as unarmored for the purposes of any features. While an armor is integrated into your flesh in this way, it cannot be removed against your will. Only one suit of armor can be integrated in this way at a time; if you attempt to integrate another, the first is removed from your body as part of the same long rest.

Plantar Piston

Muscles in the lower leg are replaced with mechanical stabilizers. Your walking speed is increased by 10 feet.

Tether Chain

Weapons you wield have the Thrown property, with a short range of 20 feet and no long range. A weapon or unarmed strike thrown in this way returns to you immediately after you make the attack.

Torque Supercharger

By supercharging the tensile forces within your weapon, you can cause the recoil from a blow to cut through other foes. Once per turn, when you hit a creature with a melee weapon attack, you can deal damage equal to your Strength modifier to a creature within 5 feet of the target. While you are raging, this damage is increased by your Rage Damage bonus.

Toxin Bomb

Metabolic waste products are stored within your body for later use. As an action, you can expel these toxins, forcing creatures within a 15 foot cone of yourself to make a Constitution saving throw (DC = 8 + your Constitution modifier + your proficiency bonus.) Creatures that fail this save take 2d6 poison damage. This damage increases to 3d6 at 5th level, 4d6 at 11th level, and 5d6 at 17th level.

Psychomechanical Upgrades

It is not enough for your body alone to be perfected; your mind, too, must be augmented. Choose one of the following upgrades.

Babylonic Speaker. You can read and speak all languages.

Cognito Filter. When a creature makes a statement, you can expend your reaction to force it to make a Charisma saving throw (DC = 8 + your Constitution modifier + your proficiency bonus.). On a failed save, you detect whether or not it was lying. Once you use this feature, you cannot use it again until you finish a short or long rest.

Infravisor. As an action, you can activate special lenses within your eyes, giving yourself darkvision to a distance of 60 feet for 1 minute. Within this distance, creatures are marked via their body heat, allowing even invisible creatures to be seen. Creatures that lack body heat, such as many undead, appear as blackened voids when sensed in this way. Once you use this feature, you cannot use it again until you finish a short or long rest.

Venting

When you are affected by a spell that targets only yourself, you can attempt to flush it from your system as a reaction, making a Constitution saving throw against the caster’s spell save DC. On a success, you can force a creature within 5 feet to be the target of the spell instead.

Once you use this feature, you cannot use it again until you finish a long rest.

Heart of Iron

An additional heart is installed within your body, helping to maintain your system’s upgrades as well as storing a potent mixture of chemicals for times of great need. When you would hit 0 Hit Points or be exposed to an effect that would kill you, you instead regain half of your maximum Hit Points, as your iron heart automatically activates its emergency protocols. For 1 minute afterwards, you also gain the following benefits:

• You have advantage on all attack rolls and saving throws.
• You have resistance to all damage types.
• Your AC increases by 5.
• You are immune to the following conditions: charmed, exhaustion, frightened, incapacitated, poisoned, paralyzed, stunned, and unconscious.

After this effect’s duration expires, you gain 3 levels of exhaustion, which cannot be cured in any way other than completing a long rest. Once you use this feature, you cannot use it again for 7 days.
