Master Of Metal

You have trained yourself to be a master of handling, controlling, crafting with, and wearing metal.

• While wearing armor that is made out of metal you gain an extra +1 to AC with that armor.
• You gain proficiency with smiths tools.
• And you can attach metal onto your skin over a time span of 1 hour provided you have enough to cover your entire body, wearing metal on your entire body grants you a -15 to movement speed and vulnerability to bludgeoning and fire damage, but gives you resistance to piercing and slashing damage from attacks that aren't Adamantine and advantage on all Con saves.
