Sarrow Soul.
My idea is to follow a path of bone look like mini monsters as a path for a cacoon/egg on the sealing, once it glows white, a big soul fall to the grown, destroying it, just to fight the player. As i did the 1st one as a comic i enjoyed how it look and i figure it out fast how the Gear whould look like, as a stealth armor full of bones. Then at the lat one, i tryed to do a simple turnaround with movement, im not happy with the result of that one, i will retake a new pespective idea for it later.
