Arcane Armor

3rd-Level Artificer Feature

Your metallurgical pursuits have led to you making armor a conduit for your magic. As an Action, you can turn a suit of armor you are wearing into Arcane Armor, provided you have Smith's Tools in hand.
You gain the following benefits while wearing this armor:

If the armor normally has a Strength requirement, the Arcane Armor lacks this requirement for you.
You can use the Arcane Armor as a Spellcasting 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 continues to be Arcane Armor until you don another suit of armor or you die.
