Fighters who follow the Path of the Mutant Forged are masters of the battlefield and the forge. They can shape weapons and armor using the materials they scavenge, manipulating these objects with an almost magical prowess to gain unique combat advantages. Whether forging new tools from fallen monsters or adapting their existing gear for any situation, they can become true artisans of war.

Level 3: Forged Craft

At 3rd level, you gain the ability to manipulate and craft weapons and armor using the materials you find in the world around you. You can perform the following:

Weaponcrafting: As part of a short or long rest, you can forge a new weapon using the bones, scales, or other parts of slain monsters. The weapon is considered magical and lasts for 1 hour per Fighter level. While wielding this weapon, you gain a +1 bonus to attack and damage rolls. The weapon can be a simple or martial weapon, and it can have additional effects based on the materials used (e.g., a dragon’s scale might give fire damage, or a basilisk's fang could cause poison damage).

Armor Modifications: As a short or long rest action, you can modify your own armor (or someone else’s, if they’re willing). You can apply one of the following buffs to any armor you are wearing:

Reinforced Plate: You gain resistance to bludgeoning damage.
Scales of Speed: Your movement speed increases by 10 feet.
Hardened Surface: You gain a +1 bonus to AC for the next hour.

Level 7: Battleforged Enhancement

At 7th level, your ability to enhance and manipulate weapons and armor grows. You can now forge and modify gear with even more specialized abilities:

Elemental Infusion: When crafting a weapon, you can choose to imbue it with an elemental property (fire, cold, lightning, or acid) for the duration of the weapon's existence. This infusion deals an additional 1d6 damage of the chosen type on a hit.

Quick Forge: As a bonus action, you can modify one of your weapons or pieces of armor to better suit the immediate needs of battle. This could mean adding a temporary benefit like increasing your AC by +2 for 1 minute or granting an additional 1d6 damage to one attack.

 

Level 10: Master Crafter's Insight

At 10th level, your expertise allows you to forge and manipulate your gear with greater precision and creativity:

Advanced Crafting: You can now forge weapons and armor from more rare and powerful materials you acquire from formidable creatures. These items last for 1 day per Fighter level, and can have more potent effects based on the monster materials:

Chimera's Hide Armor: Grants immunity to one damage type (acid, cold, fire, or lightning) for the duration.

Beholder Eye Weapon: The weapon gains the ability to cast Ray of Frost or Disintegrate once per long rest, depending on the type of eye.

Hydra Venom Blade: Each time you score a critical hit with the weapon, the target must make a Constitution saving throw (DC = 8 + your proficiency modifier + your Strength or Dexterity modifier) or be poisoned for 1 minute.


Improved Armor Modifications: You can apply a more potent effect to your armor. Choose one of the following:

Unyielding Ward: You can add +2 to your AC for 1 minute.

Absorb Energy: Once per day, when you take damage from an attack, you can use your reaction to absorb energy, granting you temporary hit points equal to half the damage taken.

Weapon Master's Veneration

At 15th level, you can now craft and wield powerful, one-of-a-kind weapons and armor by channeling the power of your fallen enemies. Once per long rest, you can create a Legendary Weapon or Legendary Armor by using the remains of a defeated creature or enemy.

Legendary Weapon: This weapon is infused with the creature's essence and grants a +2 bonus to attack and damage rolls, and can have special effects based on the creature (e.g., a weapon forged from a dragon’s heart might allow you to breathe fire once per day, or a weapon made from an ancient treant’s bark could have the ability to summon Entangle).

Legendary Armor: This armor is also infused with the creature’s essence, granting the wearer resistance to damage types related to the creature’s nature (e.g., a creature made from a fire elemental’s remains might grant resistance to fire), and +2 AC.

Level 18: Master Of The Forge

At 18th level, your ability to manipulate weapons and armor reaches its peak. You can now craft an item called the Mutant’s Aegis, a powerful artifact of your creation that lasts indefinitely.

Mutant’s Aegis: Choose one of the following items to craft, each of which embodies a combination of your best creations:

Eternal Blade: This weapon can change form between any simple or martial weapon of your choice. It deals an additional 2d6 damage of a chosen elemental type and counts as a magic weapon. Once per day, you can cast Plane Shift while wielding it.

Aegis of the Mutants: This armor provides +3 AC, resistance to all damage types, and grants you the ability to cast Shield at will.
