Martial Archetype: Ironclad

</style>

## Martial Archetype
At 3rd level, a fighter gains the Martial Archetype feature. This document presents a new option for this feature: the Ironclad.

### Ironclad
Ironclads are warriors that, through some ancient demonic ritual or pact with a fiendish master, have been transformed. An undying rage burns in their blood, granting them powers dark and sanguine, often requiring their blood be spilt in the process. An Ironclad on the battlefield is a terrifying thing, only seeming to get stronger the more pain they endure and inflict upon themselves.

#### Burning Blood
<p class='prereq'>3rd-level Ironclad feature

You can unleash the infernal fires in your heart to grant you strength at the cost of blood. As a reaction when rolling initiative or as a bonus action on your turn, you can undergo a transformation for 1 minute or until you dismiss it as a bonus action. While transformed, you gain the following effects:

- When you transform, choose a number of d4s up to your proficiency bonus; these are your Blood dice. At the start of your turn, you lose hit points equal to a roll of your Blood dice.
- Your weapon attacks deal an extra 1d4 fire damage for each of your Blood dice.

#### Inflame
<p class='prereq'>7th-level Ironclad feature

Tempered by the inferno blazing within, you gain resistance to fire damage. Additionally, fire damage dealt by you ignores resistance to fire damage.

#### Combust
<p class='prereq'>10th-level Ironclad feature

When you use your Burning Blood transformation, you can increase your Blood dice to d6s and emit an aura of infernal flame within 10 feet of you while your transformation lasts. A creature that starts its turn in this aura takes 1d4 fire damage for each of your Blood dice.

#### Black Blood
<p class='prereq'>15th-level Ironclad feature

The rage boiling in your blood becomes so intense that it lashes out at any who attack you. Whenever a creature deals damage to you while within 10 feet, it takes 1d10 fire damage.

#### Brutality
<p class='prereq'>18th-level Ironclad feature

If you use your Burning Blood transformation, choose the maximum number of Blood dice, and use Combust, you can enter a brutal pain-fueled rampage. Your Blood dice are increased to d8s, and you gain the benefits of the *haste* spell while your transformation lasts (and suffer none of its drawbacks when it ends).

#### Burning Blood
<p class='prereq'>3rd-level Ironclad feature

The infernal fury burning in your blood allows your wounds to mend quickly. When you use your Second Wind feature, you can spend a number of Hit Dice up to your proficiency bonus, roll them, and regain that many additional hit points plus your Constitution modifier.

Additionally, you recover all of your Hit Dice upon finishing a long rest.

#### Hemokinesis
<p class='prereq'>3rd-level Ironclad feature

You can sacrifice your vitality to grant you power. As a bonus action on your turn, you can roll a number of d4s up to your proficiency bonus. You lose that many hit points, and your next weapon attack that hits a creature this turn deals extra necrotic damage equal to twice the number rolled.

#### Rupture
<p class='prereq'>7th-level Ironclad feature

You can turn your pain, self-inflicted or otherwise, against your foes. Once per turn, when you lose hit points, the next weapon attack you make this turn has advantage.

#### Blood for Blood
<p class='prereq'>10th-level Ironclad feature

When your blood is spilt, you swiftly return the favour. When a creature within 5 feet of you hits you with a weapon attack, you can use your reaction to make a melee weapon attack against that creature.

#### Black Blood
<p class='prereq'>15th-level Ironclad feature

The fire in your blood grows, sustaining your body with unholy power. When you roll initiative and have no uses of Second Wind remaining, you gain one temporary use of the feature that lasts until you next roll initiative. Using Second Wind in this way causes you to gain temporary hit points instead of regaining hit points; these temporary hit points last until you take a short rest.

#### Brutality
<p class='prereq'>18th-level Ironclad feature

As a bonus action on your turn, you can enter a bloody, pain-fueled rampage. It lasts for 1 minute or until you end it as a bonus action, and it grants you the following effects:

- You lose 6d4 hit points when you use this feature, and again at the start of each of your turns.
- You gain the benefits of the *haste* spell.
- You can use your Hemokinesis feature without losing hit points. If used in this way, the extra necrotic damage equals twice the number of hit points lost via this feature this turn.

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