With this discovery, I had decided that I was still going to eat it until some of the others thought that it would be best to hold onto it and sell it later. The money gained could be of great benefit. With everyone else adamant on this end, I placed the Lord Stone and several other materials from the Jade Eagle in to my item box.
While I was still picking off the jade-green feathers to finish skinning the Jade Eagle, my exoskeleton wore off. After eating several feathers, I got the weird desire to activate my exoskeleton again. This time, my shell was more bird-like in appearance. This must be the influence of the bird's feathers. I tried flying as a test and this change made flying far easier than it had been before with even my speed being drastically increased.
