Bone Armor

3rd-Level Artificer Feature

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 armor 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.
