I watched a video not to long ago, about Bone Callers and the different things it can do or supposedly able to do.

In the YouTube video, some thru the bone caller at the mast and the skellies kept the sails in the wind until they timed out and then it showed you can throw it in the bottom of your ship and the skellies will patch holes for you.

I gave it a try today for the first time during a HG battle and the skellies just walked around on deck when thrown at mast and when I threw one in the bottom to fix holes they walked to the top deck.

Has anyone successful used them for any of these or other situations besides for repelling boarders?
