Bethais, Silver Dragon

Bethis had been entrapped in a magic item.  But The Right Fist found this item and broke the item in order to free Bethis.  Bethis eventually took his leave, but he left behind a gift of two scales for The Right Fist.
One is a Silver Dragon Scale of protection from cold.  It does not need attunement.  But if you attune to it, you receive the additional benefit of immunity to cold.  It is a 4 inch diameter roughly round disc and is one inch thick.  
The other is a Silver Dragon Scale of free action.  It does not need attunement.  But if you attune to it, you receive the additional benefit of immunity from being petrified.  It is a 4 inch diameter roughly round disc and is one inch thick.
