I thought just like necro, that it was my turn in IP 2. But as you said, it doesn't matter.
So we have a bound spirit. Well, time to take out the old reliable stand-by: the stunbolt.
Or even better, since most people are out of the concealment, have my spirit do it.
But until I do that, I still have the concealment going on and if that enemy spirit wants to see me, it still has the penalty.
EDIT: spirits on the material plane only have 2 IP, so it is done for this round.
