Spirit Release: Spirit Core

Spirit Release: Spirit Core is the fusion of the user and one of their summoned spirits. Being fused with one of the spirits grants the user the ability to Perform any jutsu they know how to perform including spirits, but with their own bodies. A user can not have any spirits active while fused with one. Their bodies become almost limitless just like a spirit but do not have the ability to become intangible for 5 seconds every 20 seconds.
