The Spiritualist's Devoted Servant Ability for the Dedication Emotional Focus reads thus:
Devoted Servant (Su): When the spiritualist reaches 12th level and is caught unawares by an attack (such as an attack made in a surprise round or while the spiritualist is asleep or an attack by a creature using Stealth), if the phantom is not fully manifested, it automatically fully manifests from the spiritualist's consciousness to protect its master. The phantom stays manifested as long as the spiritualist is unaware and in danger. This ability requires no action from the spiritualist.
The way I'm reading it is that if the Spiritualist is walking around without the Phantom summoned and gets jumped by enemies, the Phantom will manifest itself for the Surprise Round and then dismiss itself as soon as combat proper starts. Or, for another example, that if the Spiritualist gets attacked while asleep the Phantom manifests so long as she's asleep but disappears as soon as she wakes up.
I just wanted to double check with the community before I rule one way or the other on this for my player if I'm reading it correctly.
On a related note, if the effect is that the Phantom dismisses itself as soon as the Spiritualist wakes up or starts getting regular combat turns, would houseruling it so that it doesn't dismiss itself upset some balance with the class I'm unaware of? I haven't yet played with the Spiritualist in a game so I don't know how big of a deal that would be.
