Alloy of the Undivided

This grey mercurial liquid, shimmers with an iridescent light in its glass bottle. When attuned, a creature can use an action to open the bottle, releasing the living alloy to cover the creature's body, granting it a +2 to AC. If the creature has a natural weapon it is enhanced with blades or spines made from the mercurial alloy. Your natural weapon attacks deal 1d6 extra slashing damage.
