In worlds with advanced machinery or mad engineers, some barbarians wind up with parts of them augmented with machinery. These barbarians are augmented with powerful engines of smoke and fire which enable them to push beyond the limits of biology, unleashing brutal rampages of flame and fury.

These barbarians might have been augmented by an infernal engine or by a wizard's arcane apparatus. You can choose the form of your engine or determine it by rolling on the Augmented Engine table below.

Augmented Engine

Though modeled for the 2014 rules, this subclass uses the Burning hazard rule from the 2024 rules. It goes as follows:

Burning [Hazard]

A burning creature or object takes 1d4 Fire damage at the start of each of its turns. As an action, you can extinguish fire on yourself by giving yourself the Prone condition and rolling on the ground. The fire also goes out if it is doused, submerged, or suffocated.

 

Engine Overdrive

Starting when you choose this path at 3rd level, your physicality is enhanced beyond the natural by your augmented engine. As long as you're raging, you gain the following additional benefits:

• Your walking speed increases by 10 feet.
• You have resistance to fire damage.
• Your maximum jump distance increases by 5 times your Rage Damage bonus.

Reckless Flare

Also at 3rd level, you can cause your engine to spew fire when you lash out. When you use your Reckless attack and hit with an attack in the same turn, you can immediately spew flame in a 15-foot cone before rolling damage. Each creature in that cone begins Burning.

Overheat

Beginning at 6th level, when you cause a creature to start Burning with your Reckless Flare, you can also cause yourself to start Burning.

As long as you're Burning, your melee weapon attacks deal an additional 1d6 fire damage on a hit, and whenever a creature hits you with a melee attack, it takes 1d6 fire damage.

Cool Off

Also at 6th level, you have learned how to reduce your engine's heat while resting, enabling you to recover more quickly. Whenever you expend hit dice to regain hit points as part of taking a short rest, you regain additional hit points per expended hit die equal to your rage damage bonus.

Incinerating Endurance

Beginning at 10th level, your engine's hungry flames absorb the very worst scorches dealt to you. As long as you're raging, fire damage can't reduce you to 0 hit points.

Unstable Combustion

Once you reach 14th level, your augmented engine can now burn with unbelievable heat, pushing you to inhuman feats. Whenever you rage, you can choose to gain a level of exhaustion from the physical strain of the engine. If you do, for as long as you're raging, you gain the following benefits:

• Any other creature that takes damage from Burning while within 30 feet of you takes an additional 3d4 fire damage, and the damage they take ignores resistance.
• Whenever you take the Attack action, immediately before each attack, you can choose a Burning target and move up to half your walking speed towards them.
• The damage of your Overheat increases to 2d6.
