Martial Archetype: Forge Master
The archetypal Forge Master combines the martial
mastery common to all fighters with a advanced study of
blacksmithing. Forge Master's use superior metals to create weapons and armour much stronger than any common blacksmith could ever hope to create. When you reach 3rd level, you augment your martial
prowess with the ability to create such weapons and armour.

Honed Weapon
At 3rd level, you learn a ritual that improves one weapon beyond its normal capabilites. You perform
the ritual over the course of 1 hour, which can be done during a short rest. The weapon must be within your
reach throughout the ritual, at the conclusion of which
the weapon becomes honed. Once you have honed a weapon it is bonded to yourself, you
can’t be disarmed of that weapon unless you are
incapacitated, it will remain bonded to you while it is in your possesion and for 24 hours after it leaves your possesion.
You can have only one honed weapon. If you attempt to hone a second weapon, you must
break the bond with one of the other one, causing it to lose its honed property in 24 hours. A honed weapon can have the damage and properties of any superior version of the weapon you know how to craft.

Repair Hammer
At 5th level, you can spend 1 hour during a long rest to create a repair hammer. This hammer will temper any damaged armour you can strike with the hammer, at the cost of an action. Provided you have the required materials in your inventory to temper it, the armour will be tempered instantaneously and regain all your temporary hit points. The repair hammer will be consumed in the process and you can only have one repair hammer active at a time.
Advanced Armour
Also at 5th level, you can modify your own armour. The armour now replaces any missing limbs, functioning identically to a limb it replaces. If the armour normally has a Strength requirement, the armour lacks this requirement for you. Additionally the armour has one special ability, choose from the following options:
Self Repair: As a bonus action, you can gain temporary hit points equal to your level in this class, replacing any temporary hit points you already have. You lose these temporary hit points if you doff the armor. You can use this bonus action a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
Muffled: You have advantage on Dexterity (Stealth) checks. If the armor normally imposes disadvantage on such checks, the advantage and disadvantage cancel each other, as normal. Additionally your walking speed increases by 5 feet.
Pugilist Gauntlets: Each of the armor's gauntlets counts as a simple melee weapon while you aren't holding anything in it, and it deals 1d8 bludgening damage on a hit. A creature hit by the gauntlet has disadvantage on attack rolls against targets other than you until the start of your next turn, as the armor magically emits a distracting pulse when the creature attacks someone else.
Inbuilt Crossbow: A small crossbow appears on one of your armored wrists. It counts as a simple ranged weapon, with a normal range of 90 feet and a long range of 300 feet, and it deals 1d6 piercing damage on a hit. Once on each of your turns when you hit a creature with it, you can deal an extra 1d6 piercing damage to that target or another target directly behind them.

This will require the cost and materials of the superior armour or weapon as normal. But the magical nature or enchantment will be preserved in the process.

This process will also not work on daedric artifacts.
