Spirit Island's expansion spirits require genuine understanding of the core game to use effectively. Playing Lure of the Deep Wilderness without understanding standard presence placement creates confusion. Playing Many Minds Move as One without understanding the basic combat sequence creates chaos.

For established Spirit Island groups adding Jagged Earth spirits for the first time, I recommend introducing one new spirit at a time rather than replacing the full player set. Keep one experienced player on an established spirit for stability while one player tries the new spirit. This gives the new spirit player support while the new spirit's design can be appreciated in context.

The spirits in Horizons of Spirit Island are designed to be the most accessible expansion spirits, making Horizons the correct first expansion for groups not yet comfortable with the base game's eight spirits.
