The armor is a gift from Tiamat to a hero in her service. It has its own sentience and is chaotic evil. It encourages feelings of anger and hostility towards Metallic Dragons. It grants advantage on social interactions towards Chromatic and other Dragonkin (Kobolds, Wyverns, etc). 

This armor grants advantage on saves against Dragon breath weapons and grants automatic saves against Metallic Dragon breath attacks. It also grants the weather the ability to speak and understand Draconic. While using any effects of the armor your eyes turn into the slitted eyes of a dragon.

The armor is fine with being removed. It insists it is cleaned and placed somewhere clean and dry when not worn. It has intelligence of 15 (+2), wisdom of 12 (+1), and charisma of 17 (+3). If the wearer upsets the armor it will either become inert or attempt to take over with a charm effect DC 15 charisma save or be charmed for 12 hours.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
