You gain the Mending cantrip.

You gain proficiency with all Artisan's Tools, Martial Weapons and Heavy Armour.

You may choose to throw a warhammer, maul, or smith's sledge as if it were a ranged weapon, with 20/60 range.

Light hammers can be thrown twice their typical distance.

You may use your Channel Divinity to call a hammer that you have bonded with back to your hand, the distance this hammer can travel has no limit, but if someone bonds with your hammer, or if the head becomes separated from the handle, you lose the ability to call it.

Bonding with a hammer takes a day's worth of work in or as a blacksmith (or a similar role) with the hammer. You may only bond with one hammer at a time.

Once per day as a bonus action, equal to your Wisdom modifier (atleast 1), you may summon to your hand a Light Hammer, Maul, Warhammer, Smith's Sledge or a set of Artisan's Tools from your celestial patron's forge.

This is a finely crafted "masterwork" item that will last until you stop using it, and then will fade out of existence, returning to your celestial patron's forge. The hammer must have impacted something within the last 30 seconds, else it fades from existence, if you conjure the Artisan's Tools, they fade after 10 minutes of not being used.

As you craft tools and weapons, you can bind part of your soul to the item that you craft, granting you certain powers that you, and only you, may benefit from. Typically this involves mixing your blood with metal as it is being cast as an ingot, or using your blood as flux for the forging.

Normal rules apply for crafting items.

You may permanently reduce your Intellect, or Wisdom by 1 to give a set of Artisan's Tools advantage on all rolls with them.

You may permanently reduce your Strength, Constitution or Dexterity by 2 to craft armour or a weapon that has a +1 bonus and everyone else that touches that item will be the target of a Bestow Curse spell as if you had cast it.

If the item is destroyed, you regain the parts of your soul that you gave, returning any sacrificed stat that was inside that item.

Level 14.

You may craft Artisan's Tools without having to sacrifice Intellect or Wisdom, and any sacrifices taken previously are returned to original levels.

You may craft weapons and armour as before, but with only a sacrifice of 1 instead of 2 (affecting any stat sacrifice you prior gave), also any new weapons or crafted this way now gains a +2 bonus.

You are immune to cursed aspects of an item and you can gain whatever normal or magical beneficial ability that they posses without any risk of harm or injury. The item still possesses its curse but it will never affect you.

Any intelligent items also pose no threat to use them as you bend them to your indomitable will.
