Banshee Whistle

Blowing the whistle creates no sound.  Instead it summons a  living skeleton.  The skeleton knows only what happened to it while in possession of the current owner except for the first blow when it changes hands.  You can ask it questions about its previous owner only until it goes away.  Once it is used again it only knows or remembers you.  It will reamin summoned for 12 hours or until you release it.  A long rest is required before you can use it again.  It is one bonus action to summon the skeleton.
