Quick question about Vaylen jumping bodies

Hello to everybody!

My second post and I’m still making a great show of my dullness :frowning:

This is the question: When the Vaylen jump bodies, the Will- and Perception- rooted skills remain exactly the same as they were in the previous host or you factor the new root and then add the advancements (if any) made while in the previous host?

I suspect I’m making some kind of basic mistake here…

Thank you in advance!
