Specialty of the Bonesmith

Bonesmiths are Artificers that use necromancy to empower their infusions. They specialize in using their artificer training combined with necromancy to create a suit of Bone Armor that can be augmented with the remains of the dead. Generally, they use the remains of the dead and their own life essence to fuel their magic, but some powerful Bonesmiths are able to imprison the souls of the fallen to feed their creations.    

Tools of the Trade

When you adopt the Bonesmith specialization at 3rd level, you gain proficiency with heavy armor. You also gain proficiency with smith’s tools. If you already have this tool proficiency, you gain proficiency with one other type of artisan’s tools of your choice.    

Bonesmith Spells

Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Level	Spells
3rd	Bane, Inflict Wounds
5th	Spiritual Weapon, Ray of Enfeeblement
9th	Animate Dead, Vampiric Touch
13th	Blight, Evard's Black Tentacles

Bone Armor

When you adopt the Bonesmith specialization at 3rd level, you learn how to use your artificer training combined with necromancy to create a suit of Bone Armor that can be augmented with the remains of the dead. Your Bone Armor serves as a conduit for your magic. As an action, you can augment any armour with a corpse of medium size or larger or a pile of bones of equal size, turning it into Bone Armor, provided you have smith's tools in hand. You gain the following benefits while wearing Bone Armor:

The Bone Armor takes on the properties of the armor you augmented.

If the armor normally has a Strength requirement, the Bone Armor lacks this requirement for you.

You can use the Bone Armor as a spell casting focus for your artificer spells.

The armor attaches to you and can’t be removed against your will. It also expands to cover your entire body, although you can retract or deploy the helmet as a bonus action. The armor replaces any missing limbs, functioning identically to a limb it replaces.

You can doff or don the armor as an action.

The armor grows a pair of skeletal gauntlets that count as simple weapons with the light property that deal a 1d8 of necrotic damage when they aren't carrying anything. You may use your Intelligence modifier instead of Strength & Dexterity for your attack & damage rolls.

The armor continues to be Bone Armor until you don another suit of armor, or you die.

 

Necrotic Sacrifice

When you adopt the Bonesmith specialization at 3rd level, you learn how to use your own life essence to empower your damage dealing spells and your Necrotic Infusions, using sacrificial dice.

Sacrificial Dice

You have 4 sacrificial dice, which are d6's. A sacrificial die is expended when you use it. You regain all of your expended sacrificial dice when you finish a short or long rest. You gain another sacrificial die at 9th level and one more at 15th level.

Necrotic Spell

Whenever you cast a spell that does damage you can expend a sacrificial die to add necrotic damage equal to the sacrificial die. You take damage equal to half the sacrificial die rounded up.    

Necrotic Infusions

When you adopt the Bonesmith specialization at 3rd level, you learn how to customize your Bone Armor by infusing it with the remains of the dead.

You can choose infusions from the Necrotic Infusion list instead of the Artificer Infusion list.

When you gain this feature at 3rd-level you can replace any amount of Artificer Infusions you know with Necrotic Infusions.

Here follows the list of Necrotic Infusions:
