While wearing this armor, you gain a +3 bonus to AC.  You have +2 bonus to AC when attacked by a fiend or devil; however you have a -2 penalty to AC when attacked by any good alignment.  You have advantage on saving throws against the Frightful Presence and breath weapons of dragons, and you have resistance to cold damage.  

Also you may levitate and fly around 3x per long rest with the command phrase "I am soaring virtue."  

If the armor is worn while wielding the companion 'Xanthriel's Imperial Bow of Virtue' then any attack made directly against you causes 1d6 cold damage against the attacker, provided that it is not a spell or ranged attack (melee attacks only).

Additionally, you can focus your senses as an action to magically discern the distance and direction to the closest silver dragon within 50 miles of you. This special action can't be used again until the next dawn.

The wearer has no disadvantage to stealth checks while wearing this armor.

If the wearer initiates an attack against a good aligned creature/entity then the armor reverts to a normal dragon scale mail of silver.

 

This armor consists of a coat and leggings (and perhaps a separate skirt) of leather covered with overlapping pieces of metal, much like the scales of a fish. The suit includes gauntlets.
