Did Viking warbands bring Sami Shamans with them on raids?

/r/Norse sent me here for a better answer.

I read that when going on raids, vikings would bring a Sami Shaman (who were respected in many Scandinavian societies) with them for any magic related needs, are there any credible sources of this?

This seems like something from a fantasy book or movie why not bring there own shamans that spoke norse and worshipped the asatru aswell?
