Shards of this shiny reddish-gray substance adhere to the outside of its container. The potion has three doses. It may be consumed in one action allowing a Medium or smaller creature to immediately transform their skin into iron for one hour. This duration may not be shortened.

While transformed the creature weighs 65 pounds heavier than normal. They also have an armor class of 18 (as plate) but they do receive their full dexterity modifier. While this is similar to a Potion of Invulnerability, it does not confer any immunities or resistances. It does not provide the ability to breathe under water. The transformed creature is however appropriately vulnerable to rust-monster attacks.

Wearing other armor (beyond a shield) provides no benefit but may limit dexterity modifiers as normal.
