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

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, you can spew flame in a 15-foot cone. 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 weapon attacks deal an additional 1d10 fire damage on a hit, and whenever a creature hits you with a melee attack, it takes 1d10 fire damage.

Incinerating Endurance

Beginning at 10th level, your engine's hungry flames absorb the very worst scorches, converting the energy into strength. As long as you're raging, fire damage can't reduce you to 0 hit points. Additionally, whenever you take fire damage, you can use your reaction to roll a d6 and add the result to the next attack roll you make before the end of your next turn.

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 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 your walking speed towards them.
• The damage of your Overheat increases to 2d10.
