I was browsing through the shop and noticed a 3 Body Binding and it appears to be fairly similar to a triumvirate, which, from what I've read, cannot be undone, or at least not easily anyways.

Does anyone know if the same is true for the 3 Body Binding?

Also, what differences has everyone noticed in interactions with their spirits since getting a 3 Body Binding or Triumvirate?

What I have noticed about everything from the shop is that getting it to work is the problem. Stopping it is as easy as forgetting you have it.
