Aura faint conjuration; CL 3rd
Slot armor; Price 2,250 gp; Weight 25 lbs.
The fine links of this +1 chain shirt form a pattern of roiling clouds. On command once per day, the wearer can transform it into thick fog that fills his space and provides concealment (20% miss chance). This mist moves with the character. Effects that disperse the mist or destroy it cause the armor to reform into its solid shape on the character's body, as does speaking the command word or entering a place where the fog-magic doesn't function (such as underwater). If the character tries to don another suit of armor while the Mistmail is in fog form, it reforms at the character's feet.
When it is in Mist form do you still get the AC bonus? Seems like you should be trading it for the concealment. How long does it last?
