I haven't seen the end result of Unchained yet, and have only read the bits and pieces here on the boards, but I was wondering if anyone who has the book has compared it with the Spiritualist from the Occult Adventures playtest? Does the Spiritualist sort of resemble the changes that were made to the Summoner in Unchained?
The Summoner itself is largely unchanged, but the eidolon has moved a bit towards the Spiritualist's phantom, with archetypes that progress with specific powers as you level up. They still have an evolution pool, so they're much more customizable than the playtest phantoms.
